Just want to announce that I set them back up in the living room today after a few weeks without them. Whilst tuning them, "Rain (Female Vocal Version)" from the Cowboy Bebop OST started playing. I haven't cried to that music in a long while. But I did. F
Just ordered the Heresy III brand new.These were hard to find here in EU. Everyone was only offering the IV: Dont want the port and too expensive for me. Currently running KEF Q900. Haven't heard horns before, at least here in my apartment. I also have.a SVS PB2000 subwoofer and minidsp + Audyssey XT 32 (Denon X3500H). I think i will be fine with the "lower" base. I wanted the III because its sealed. Should get them in a week, will be planning on raising them about 40cm. Main reason and the "aha" moment to get these was the appreciation and realisation of the importance of a tight mid base slam and the "speed" these should give. I usually listen pretty quiet during the evening, around 75db + dynamic EQ at -15 offset. (about 8db hot). Hey Z, what do you think? Will i get an improvement or a paradigm shift? 😎
Z Reviews Most current Denon multi channel receivers let you use unused channels in biamp mode. Would that work well with these speakers? I think you can adjust and set the levels individually.
I have had mine since 1979(grandpa) Always sat on the floor. Look brand new, never had any issues at all. Still sound great. I have a amaha sub woofer and a Yamaha RX-A770 receiver.
I have the Heresy IIIs, and use them as maxi-bookshelves with a sub. They work great. They will go to "death ray" levels if you ask them to, but they are pretty amazing. I find that they portray acoustic percussion in an incredibly realistic way. I run them full range, with the sub coming in to boost up the low frequencies. The sealed version certainly rolls off below 60 hertz, and needs a sub to get the slam we'd want as modern listener.
Yes they are built-in Hope Arkansas. In the early 70's I was the east coast rep for Klipsch knew Paul Klipsch personally quite a character. If I recall Klipsch Cornerhorns were about 3000 a pair back then. I wish I'd kept mine they were in Rosewood, hell today the wood alone would be 10K.
I own the original Heresy's and I'm well versed in the heritage series from Klipsch. Take the speakers down off the ridiculous pedestals for starters, Next situate the speakers each in a corner and utilize the room dynamics acoustically as Paul Klipsch had originally intended, as with all the heritage series speakers all you need is two separate corners and the wedges you had under them originally trust me on this you will rediscover those speakers.
I would totally recommend using a tube amplifier for those Klipsch Heresey IV speakers. I have the same speakers in black ash, With a Black Ice Audio F-35 tube amp and a Black Ice Audio SS-X sound stage expander that alows me to boost the bass and expand or shrink the sound stage. I have enough base that the downstairs Neighbor complains often. I do want to add a subwoofer, though. The best part about these speakers is that no matter where you are in your living room they sound amazing. You don't have to sit center stage for these.
To answer the question at 30:18, assuming the drivers behave like a linear non-deforming piston (they don't exactly but it's close enough for small excursions), the volume displaced by one is given by: V=(1/4) h pi d^2, where h is the driver excursion distance, and d is the driver diameter. Equating this volume with the volume of a second driver, d_2, that will have an excursion of h_2, we can simplify to: (h_2)/h = (d/(d_2))^2. In other words, the relative displacement of two drivers is equal to the inverse of their relative diameters squared. In the case of a 12-inch vs a 4-inch driver, this means that the 4-inch driver requires 9 times the excursion of the 12-inch driver to achieve the same volume displaced. Obviously, you could plug in any driver diameters to that formula for quick calculations.
skizzlemane1 Well, using the formula, we can find that a 4-inch driver would need to move 54 mm to displace the same amount of air as a 12-inch driver moving 6 mm. As for the other sizes, A 5.25 inch driver would need to move 31.3 mm. A 6 inch driver would need to move 24 mm. An 8 inch driver would need to move 13.5 mm. A 10 inch driver would need to move 8.64 mm And of course these are all only approximate; the larger the excursion the more error there is in the number, since in reality the driver does not deform perfectly linearly. Hope that helps!
Originally. the Heresy was intended as a center fill speaker for use with a pair of Klipschorns. As such it was designed for low distortion from the mid-bass up and to let the big folded corner horns do the heavy lifting for the deep bass. The Heresy [I] to III were sealed boxes, acoustic suspension/smallish infinite baffles. The story is that when Paul W. Klipsch was designing this speaker with a direct firing woofer without a bass horn it was heresy, hence the name. Yeah, old dude here.
@@wa2368 Tektons are an incredible value. However, once you become accustomed to the astonishing detail and transient response of horn tweeters, it's hard to be satisfied with any direct radiator.
Came to comments to say the same. No reason to go through all the trouble and expense to add subwoofers (to do it right and match the quality of the Heresy, it will take two subs and a DSP or active crossover and multiple amps - as he scratches the surface on) - which is a hole not worth going down and will be a source of endless frustration and constant tweaking for Z. By the time you've properly figured out your subs, you are taking up more physical space and spending more money than if you just bought better speakers from Klipsch. As he said, these are the cheapest Heritage Klipsch speakers. They were originally designed to be a center channel speaker! Yes, they've been redesigned a lot, but these are still Klipsch's bookshelf models. Get the damn full size already. Get the Cornwalls or even better, a pair of Chorus IIs (used - because they don't make them anymore), which replaced the Cornwalls before they brought them back with a re-design.
It isn't truly Heritage until he covers the fully horn loaded Klipsch Heritage line. Of course, I mean the K-Horn and La Scala. That's where the Heritage series shines, try 1 watt, I dare ya.
I own a pair of Klipsch Heresy H 100 speakers from 1975, still the best sound around with my other equipment, no intensions of upgrading or selling the speakers, hope my kids realize what they are))
My boy is growing up 😭 Now he knows.... The team that designed these in Hope Arkansas have captured his soul and La Scala's and Klipschorn's will invade his dreams ......
@@itsme-ri5mw I understand the request, but clearly youre not a frequent watcher of Z, his reviews are always full of his personality. And thats a major part of this channel is that he apologetically reviews things in exactly the way his brain forms the words. And along with that is what he chooses to be interested in, hes not making the video for his personality, you just happen to get all of it with the review anyways. If you stick around youll find hes just a dude whos enjoying what he loves, and theres nothing wrong with that.
you hit the nail on the head I've noticed all the speakers I have owned from klipsch with dual wire post have benefited greatly from removing those cheap jumper clips and bi amping them but hell just removing the clips and replacing them with good wire makes a difference
This might me be the wackiest/greatest review I have yet seen.. It's like all of Zeos' time testing gear has come full circle.. With the same goal we all have and that is, audio bliss. It seems like, for now, he has found it!!
in general all speakers need subs. They do a solid 40hz in room, for most subs wouldn’t be needed so Robinson’s not wrong, but if you want to listen to dj shadow three Ralph’s or experience leftfields swords in all there glory yep subs are need
Last summer I spent a nice chunk of that time repairing/refurbishing a sansui sp-5500x that I got for pretty cheap. The cross over needed new caps, the woofers needed work before their surrounds were completely gone and the all of the horns were blown. Caps were an easy fix spare the horse glue holding down the old rubicon and the woofer was salvagable even though they used While I was able to find replacement parts for the squawker/tweeter horns I could not find an original replacement part for the super tweeter horn but I found a set of super tweeters that uses the same driver material found in the larger horn and the super tweeter and normal tweeter have matching sound signatures so it worked out far better than I ever anticipated in the end. Anyways I have to agree, there is something to three-ways and large speakers like this. Those drivers simply do not move as much as you expect them to move and having each driver doing less just leads to the whole thing sounding so clean. I can see why klipsch makes these style of speakers still as does JBL in their synthesis line.
Your frequency balance problems when you put them on stands was probably because you put them on stands. That put the horns directly on ear axis, for one, and more importantly, you lost several dB of bass because you were no longer getting floor reinforcement of those frequencies. They're voiced to be on the floor, with all the acoustic effects that has. When you put them up in the air, that's gone.
I love how you talk about your different speakers being different flavors of ice cream WHILE AT THE SAME TIME there's a neon ice cream shop sign outside your apartment in the background.
this reminds me of my childhood (80s) speaking of vintage my dad had a Marantz receiver with 4 12" Cerwin Vega floor boxes with the orange surrounds, to a kid that was the loudest thing in the world!
I loved the neon ice cream sign in the review. I've learned a lot by watching these videos . I've thanked and blamed Zeos tons of times for my jbl 305s , along with the aune x1, and headphones, and the new pair of Jamo c93 for my home theater, and the micca OoO that just make no sense on how such a small speaker makes such a great noise. Enough rambling me! Thank you for educating me on the complicated world of audio!
Their is pair of these in my parents basement, as wedding present in 1964. They look identical, I wonder if the mice has gotten to them? Still in the original box. Wonder if they are worth anything? 55 years old...
Been following reviews for the Heresy IVs for a while and this is the best review so far. Some reviewers said to match these with a tube amp to temper the brightness; Zeo's better, cheaper solution? DSP. Some reviewers have said it's not the best for modern music but good enough bass, and only excellent for the type of music they prefer; Zeo's solution? Cheap dual/sub. Efficiency discrepancy between horns and woofs at high volumes? Bi-amp w/ DSP and subs. Tells you exactly what you need (or what you don't) for what you want out of these speakers.. even numbers for dsp. All are affordable options too. Great fk'n review.. only criticism is no upside down demo lol. I really need to start saving up for these D:
A tube amp is on my list of things to try. But I want the volume. The Gain. The FFFF.. I will beat these with my magic stick until they are Thor's Hammer.
@@ZReviews Hook those babies up to your Crown. I dare you. I think that you will be happy with the control, and clarity that you get. I have a Crest ProLite 2.0 running my 590's, and a 600 watt Carver/Sunfire pushing an HSU 12" sub, and it kicks major ass. My Klipsch Chorus ll's will be with me until they go to my son in my will.
@@ZReviews IMO the move to make with these speakers is pure "Class A" baby!!! You love the RebelAmp for HPs so get the equivalent for these babies they deserve to be the pretty girls at the ball. Something like First Watt J2, used Pass Labs X250, used Krell, or something similar.
21:51 “Sofi needs a ladder” -Deadmau5 ...incase anyone was curious 45:53 what? 🤷🏻♂️ “I went to look at the temperature in kelvin for bulls of hue who don’t know”
. Zeos landed 'kinda in the middle of several different ways to accomplish a better sound here. He really sort of Frankensteined the chain I think, just because that was the equipment he had on hand. I'd be happy to answer some questions 'bout it. Acid Jazz, Funk & Brass 🔈🔉🔊
Enjoyed the review, years ago had the predecessor Heresy and had the dealer remove the floor mounts as well ,placed them at ear level and loved them with my Velodyne 15 inch digital sub.had them set up in a 5.1 config for home theater ,had original RF7 and just replaced them with the RF7 |||'s . I know they're big and heavy but after listening to your rave Heresy review would love to hear your take on the RF7 ||| , bad or good , personally I love the way these sound on music and movies .
The floor reinforces the bass (think of it as a built in corner) and reduce the highs because they're not at ear height beaming at you. I think you created problem three by putting them up in the air.
Zeos .... .... .... . . its the first time ive heard your voice manner in that level tone/excitement/disbelievement ... good for you ! they look fooking great !
Three weeks ago, I received my pandemic speakers, new Cornwall IVs and my sheer joy has been similar to Z's. One of the reasons I chose them was that I could save $1k on the amp. I don't need the subs either. I did raise them up six inches and put them on wheels so that they could be turned depending on the sound stage that I want. 16'x12' room.
Brandon Burr It’s nice to see Z reviewing klipsch heritage 👍🏼 a klipsch hereitage line review is incomplete without a tube amp imo though. Tubes and klipsch go hand in hand. Putting my pair of heresy 1’s on stands and in the corners made a huge difference in soundstage and bass in my living room. They were on the floor and against the wall before and they were uninspiring. But even in their new position you can still tell exactly where the low frequency cuts out and there’s just nothing below that point. So unless you’re ok with missing a significant portion of the information in your recordings below the cut off point, you need subs. But if you’re going to add subs, might as well get Cornwall’s. And if you’re putting Cornwall’s in the corners, you might as well get klipschorns. 🤷🏻♂️ which is what I ended up doing. Problem is my used klipschorns cost me the same as this new pair of heresy iv’s. Actually less when you factor in the subwoofers and stands. That’s the problem with klipsch. I love klipsch and have for my whole audiophile career. But the vintage heritage line are so robust and last forever. For me it doesn’t justify spending 10x more on a new pair. If you have the space I recommend used Cornwall’s or klipschorns. La scalas and belles run into the same bass problem as the heresies.
i picked up a pair of unfinished heresy 2,s at good will for $12 a piece grills were screwed on lol they have even less base as your new ones but with a sub they are great sanded them and finished them in dark walnut stain now they look and sound great
If there is a driver balance problem, you cannot fix it by normal biamping. You have to have different gain control for each channel. Using a dsp or AV amp is one solution otherwise you have to use separate gain controls or attenuators for each amp.
Z! I really like the direction you are going with the Heresy! Are you going to install two more crown and two 15" Subs? Klipsch makes them? The Klipsch guys say it's good to listen to them positioned so the horns cross in front of your ears? Did you consider the Cornwall IV? (short for corner wall ) It sure makes a lot of sound without moving, doesn't it?
Zeos, you could add a diy horn sub to get more closely matched sensitivity, and serious gut punch capabilities. Once you get hooked on horns, all else pales in comparison if you like to rock, and live for visceral impact.
I love the comments about the Klipsch, I'm also an owner of Klipsch, but I would say if you were interested I would get the SL-15 Cerwin Vega, they do not require subwoofers at all, or stands. If I would put these in a price category they are Klipsch La Scala, but even the La Scalas require a subwoofer. I know this because my friend owns a pair. My SL-15s are only $1000 brand new.
Hi my friend love all your videos please can you tell what those round looking crab things are on your window sill are please thank .. and keep the videos coming
Just wait until you raise them up 2 ½ feet. Much better height imaging. I also tried the extreme toe-in idea and that is better than straight ahead or minimal toe-in, in my opinion...way deeper soundstage and even better detail. I put mine up on end tables and I agree with you - can’t live without them. They bring the music to life, ESPECIALLY vocals. Good Lord, the vocals.
Beautiful Veneer. Simple solution. Put a volume control on the horns. You have the "straps", so put a volume control after the speaker and before the horns. Problem Solved. Much simpler and cheaper $$$$$ than a second amp. You're Welcome. Now I know what to do when I buy a pair of them. If i really feel the need in my listening conditions.
SUCH A CUTE CAT!! Considering these speakers myself or Forte III. Thinking three Heresy IV to use as LCR channels for Home Theater since they low profile but I am considering alot of different floor standers. Too many good ones available right now is a pain in the ass! Appreciate the great reviews! Did I mention you have an awesome cat?
Nice seeing beefier more substantial speakers w/ larger drivers. Z this your best review ever, I hope you do a review of the Cornwall's next, wondering if you'll keep them too. ( Steve Guttenberg have those broken in too) This the most complete, best review I've ever seen for the Heresy's, good job Man .
now they have my attention. it took your review to make me even want to return to looking at these. my brother in law had a pair of these in the 80's and i hated them. he ran them with a old school Pioneer 100w/channel receiver that ran them to incredible sound levels but it was nothing but an assault of mid-range that nearly killed me. their clarity was incredible but there was no full-range sound to them. this could get interesting. thanks Zeos...
What sets you apart from other audio reviewers is that you improvise as your going through the speakers while reviewing... not easy to pull off the way you do... nice work...
Hi Zeos! Did you also check out the possibility and the upgrade option from GR Research for the crossovers? Very nice video and interesting approach to drive the mid-highs and lows separately. Perhaps one reason more to check out the xo upgrade from Danny 😉
That's why the PS audio exchange exist they have kits where you cannot rebalance the speakers where you can bring more bass out of them and cut back on the mid and I by her ex exchanging Parts off of the crossover just by changing certain pieces off of the crossover board you can change the efficiency of the speaker and they do sell kits so you can change them up and you won't have that problem anymore and you won't have to run two amps to one speaker
And I have been using their speakers for years and I have not only been using them I have been modifying their crossovers a years to get better sound out of them and there are kits you can buy to change the capacitors the block resistors and the coils on the crossover boards that'll give you more Bass and more highs and mids I know those particular speakers that you have there
Thank you for your review which helped me soo much after recently purchasing the Heresey 4, and was wery disabopinted AFRET REYING THEM for the firest 4 weeks the sound was thin and whed inreasing the volum was getting more thiner, after seeing your goog review, I placed them higher and adjester the speakers sound on my also new Marantz7013, but I still may be thinking about pre amp, and I 'm not sure if I can do that with connecting my old Onkyo656 with the new Marantz 7013? thank you appriciate it.
The JBL L100 which is similar in size also really needs to be elevated beyond the shorty stands they offer. Which may be why JBL classifies them as bookshelf speakers instead of floor standers. Anyway, the surround on the Klipsch is made of treated cloth and is known as an accordion surround. It's very commonly used in high efficiency pro sound drivers. The cabinet for these is now and always has been undersized for a twelve inch driver to produce truly deep bass. But it is not strictly a mid-bass driver as it will play well down into the 50 hertz range which is most certainly in the bass frequencies. However, in an elevated situation such as this you probably will see a dramatic roll off starting around 65 hertz. But as Z said the sound you get in your room will vary. In any event his assessment is accurate. You need a sub. But then to get the best performance from pretty much any speaker that doesn't have multiple large subs built in you need a sub, or two. Yes, really. You think you don't until you try them and then, wow, what a difference. Now, I know a lot of people think bass is the only reason to pay more than sixteen dollars for a speaker and will think these are a rip off. Other folks will fuss about the lack of extension on the Klipsch but then pay five thousand bucks for a pair of bookshelf speakers that roll off below 150 hertz and claim they don't need subs for them. Okay. Truth is these speakers have a lot of competition at three grand. But just as each of these competitors can do something the Klipsch can't. The Klipsch's can do scale, dynamics and realism in a way that I've only heard from one other speaker at the same price point.
I had a set of 1990 Klipsch Chorus II speakers. Fabulous all of these years. Just lost them to Hurricane Ian storm surge flooding. Will probably replace them with the Klipsch Heresy IV with a similar set-up that Z Review has in this video!
Every time I watch a Z Reviews video and hit blinds are open. I really wonder what people are thinking when they look up and see a guy walking about pointing and yelling at things in a room with GoPro on him.
Good point on the woofers, I think there is some sort of Doppler effect when you try too much bandwidth on drivers. Did you consider mounting the Klipsches on top of the subwoofers?
Been looking forward to this since I first saw you had them as I have Heresy IIIs, missed 10 minutes of it working out the volume of a cylinder for the 4" driver extension question. It would have to move 54mm FWIW.
Actually the name says it all ,the second meaning to heresy is "an opinion profoundly at odds with what is generally accepted "as an audiophile speaker which is why some love them while others can't believe someone could love them.
. . . all that is not necessary, my Bra. Utilize a high pass filter between your subs output, and the Heritics, buy it set at 100hz. No freqs below 100 enter the Hereseys . . . the big 12” instrument speaker, then becomes an excellent mid-base/lower-mid driver, with the subs crossing with a 3d order, 18db per octave roll off, doing the down an dirty . . . try it, puts nothing in the signal path . . . you need powered subs, though. Parts Express sells the filters 😊.
Oh man I love this video but I gotta know how well can this raised up dual amp approach work with the cheaper end Klipsch speakers. How satisfying can that be for the money?
It is rather ironic that many people think that Klipsch speakers sound so 'effing great and there is a whole industry of folks out there making modifications for Klipsch speakers.
Yeah, a tad misleading. People aren't modifying brand new, modern Klipsch. The industry you speak of is there to keep 40+ year old speakers out of the landfill. New crossover, replace a blown driver, not a problem. I get it, some people don't like horns...... Some people love them!
Alot of people don't like the horn speakers but love the look and design of the Klipsch. I know some people see the price and realize with a mod, they could get the sound they want for less than buying a higher end speakers as well. Klipsch makes pretty good cabinets for their price and they're extremely flexible in audio performance.
@@Trogdor204 Perhaps, although GR Research does a lot of modifications on newer Klipsch speakers, but yeah, the Bob Crites upgrades are more for the older ones.
Most are factory replacements with parts that no longer exist from the Klipsch. Some mod the crossover but that's like changing out the ecu in a car not tossing out the engine. The Engine runs just fine with a little tune-up.
redstarwraith Just like a good American muscle sports car. There’s always a bit more you can squeeze out of it. Unless you want Tesla but where is the fun in owning that?
Have a 1970's pair of Altec Lansing speakers (complete re-build), duel 10" woofers, same design wrinkle paper, turn them up and that mid horn just takes over. What happened to mountain bike, replaced with paintball guns.
You should definitely try the Solaris with them (in you new home I guess). The Solaris is such a great amp. Loved my Yamaha 3000 combo but in a reasonably sized room or with very efficient speakers the Solaris adds so much to the music that makes you emotional. Try it. Seriously. Trust me 😀
Saw a video where a designer said higher efficiency ( Klipsch law) reduces distortion and you get more sound from less cone excursion. That’s why that huge cone barely moves when rockin Think of Bruce lee’s three inch punch that sends the guy across the room. The big cone is hitting harder and faster so it doesn’t need a three inch throw... bro
I am interested in high sensitivity speaker (I have 92db German horns) but these are 99db like the Fort III.for an extra grand but the Cornwall IV is 102 so it's like doubling your power.I'd like to have something that could run off a 1 watt amp (LTA's MZ2).Heresy and Cornwall IV need a sub so I am hoping that maybe the Forte which can be run close to front wall even with that 15" well hoping that they update the Forte from a III to IV and get improvements wrought in the Heresy and Cornwall.I wish you could get a pair of Tekton SET15 which can be run off 1 watt.But this was great review though I have to digest the bia-amp option with its presumed degradation of sound unless you have some very expensive analogue x-over.Great Review Zeos
in the 70's and early 80's there were several 12 inch-woofer speakers like that Heresy that were usually placed on 10-15 inches stands and tilted back; i can recall models from Advent, JBL of course, Avid and KLH, to name a few.
I have a set from 1982 and raised them off the floor. I wouldn’t part with them. The box on mine is sealed. However I do have one issue. I think I have a driver going bad. No idea what I may do to fix it. I’m sure original parts aren’t cheap. I do want a Rel Sub and Marantz 1200 to pair with them.
I'm thinking about buying a pair of the Fives for my living room/movie setup, which subwoofer(s) do you recommend I should pair with them? (under £800.00)
Large woofers are the secret to star spangled awesome sauce! Why? Because beaming my friends! It's actually a good thing for frequencies below 1000khz. And big woofers help a lot to focus frequencies below 500hz. They won't achieve cardioid bass by any means, but they're much better than having 2 five inch woofers. Honestly, MTM designs have never made any sense to me. The center to center distance is never close enough to avoid comb filtering in the mid range (intermodulation distortion), plus they spread too much sound to all the side walls. MTM trades everything for a symmetrical vertical lobing pattern. Smh, It's so bloody stupid. It's a total failure, and I'd be glad if they chuck all D'Appolitos into the sea (not referring to center channels). Use small woofers and too much sound is hitting the side walls and floor and ceiling. It creates a muddied sound and is unclear. Small speaker drivers are best for very large rooms, or heavily treated rooms, because they're able to spread the sound far and wide. Oddly though, they lack the ability to move much air which won't fill a large room. So stacking small drivers in a line array configuration is sometimes good for large rooms. Physics affecting audio is quite peculiar, and the general public is oh so very lost and confused. If you have a small to medium room, a large 10 to 12 inch woofer which doesn't have much excursion is your secret weapon to achieve better clarity and sound staging. Small mid-range drivers are also a poor design choice for most homes. Go with a 6.5 inch (not a 4 inch) and harsh frequencies from 2 to 4khz won't be bouncing all around the room-- depending where you set your crossover point. Cardioid bass is the goal, along with a good directivity index result, especially for most home environments. Here's a good setup for increased sound staging, clarity, and decreased listening fatigue. A 3 way with a subwoofer. One 10 or 12 inch HiFi driver, just like the heresy's. High excursion not required. We want it to be able to play down to 60hz with ease, but below that is the job of the sub woofer! Possibly use 2 eight or nine inch woofers. Then a 6.5 inch mid range. Crossover region ~250 to ~4khz. Yes, moving the crossover point an octave from either of these points would still be fine and understandable. But those are general boundaries. A ~1 inch tweeter. And the sub. I'm not a fan of compression drivers. What's the point? Most people don't listen at high enough volumes to have a driver which typically doesn't measure as well. If going for a 2 way configuration. Consider 2 seven or eight inch drivers, and a ~1 inch tweeter. Focus on HiFi drivers without massive excursion or crazy bass specs. You want mid bass and mid range clarity. The sub can always pick up the low end. The crossover point will be ~2,000. Older speaker designs had a lot going for them and now with the better drivers of today, they've been perfected. Granted, they don't look like slim sexy towers. That's the only drawback.
looking at buying a pair and bi wiring them with my McIntosh ma6900 to the top section and an mc300 to the bottom n wonder if that ill work to keep up with the horns
Finish may just be sanding sealer without a true hard finish coat on top. That's a cost saving thing. Sanding sealer is much easier to buff out than a harder finish.
I bought Heresy III based on Gutenberg's review back then and no regrets. I got them for $1800/pr, seems like bargain. I live in a small place so I don't even have room for a sub or miss one too much, though I'm sure it'd be even better. I'd love to try the H IV
Hi! I tried to search through the commits and didn't find this question yet. However, I noticed that you were very impressed with the SVS Ultra bookshelf speakers. How do they compare to the Heresey IV's?
I was watching another vid about Klipsch and they stated that the Heresy was originally designed to be a center channel speaker to the Klipschorns. That explains why they don't need to go deep. The speakers that need to be looked at are the Fortes as they were designed to be stereo speakers.
I love the idea of legacy klipsch dpeakers. BUT everytime i see a review of one or the last time i spent the day at their engineering facility, i want to build new cabinets so that the driver acoustic centers are lined up and adjust the crossovers to take advantage of the increase in coherencey. After spending years designing pro sounds systems using speakers with woofers misaligned with the horns, i learned to digitally time align the drivers. The increase in coherence was revalatory.
@@ZReviews it depends on how you are doing it. Are you using the klipsch crossover or using a dsp for the crossover? The klipsch crossover parts are chosen to try to offset the time alignment by altering phase. When using the stock crossover, get a dsp with open architecture software. You split the signal, cross h.f., up, the l.f. down and add a delay to the shorter depth driver . Then recombine the signals. Use the steepest slope available. Slide the crossover points up and down together until you get as little frequecy response changes as possible. Measure physical offset and start with that for a time delay. Use a time alignment function on test gear like from parts express or dual FFT analyzer to fine tune the delay. Then adjust one crossover point, slope etc. to flattenn response.

Just ordered the Heresy III brand new.These were hard to find here in EU. Everyone was only offering the IV: Dont want the port and too expensive for me. Currently running KEF Q900. Haven't heard horns before, at least here in my apartment. I also have.a SVS PB2000 subwoofer and minidsp + Audyssey XT 32 (Denon X3500H). I think i will be fine with the "lower" base. I wanted the III because its sealed. Should get them in a week, will be planning on raising them about 40cm. Main reason and the "aha" moment to get these was the appreciation and realisation of the importance of a tight mid base slam and the "speed" these should give. I usually listen pretty quiet during the evening, around 75db + dynamic EQ at -15 offset. (about 8db hot). Hey Z, what do you think? Will i get an improvement or a paradigm shift? 😎
@@janj.5385 Yeah I swapped the Crowns to Stereo and run top and bottom off each one.
Z Reviews Most current Denon multi channel receivers let you use unused channels in biamp mode. Would that work well with these speakers? I think you can adjust and set the levels individually.

Hey Zeos I'm a Patron. I will give you $20 for them.
I have had mine since 1979(grandpa) Always sat on the floor. Look brand new, never had any issues at all. Still sound great. I have a amaha sub woofer and a Yamaha RX-A770 receiver.
I have the Heresy IIIs, and use them as maxi-bookshelves with a sub. They work great. They will go to "death ray" levels if you ask them to, but they are pretty amazing. I find that they portray acoustic percussion in an incredibly realistic way. I run them full range, with the sub coming in to boost up the low frequencies. The sealed version certainly rolls off below 60 hertz, and needs a sub to get the slam we'd want as modern listener.
. . . get a high pass filter, if you have powered subs . . . see comt above ^.
Yes they are built-in Hope Arkansas. In the early 70's I was the east coast rep for Klipsch knew Paul Klipsch personally quite a character. If I recall Klipsch Cornerhorns were about 3000 a pair back then. I wish I'd kept mine they were in Rosewood, hell today the wood alone would be 10K.
I own the original Heresy's and I'm well versed in the heritage series from Klipsch. Take the speakers down off the ridiculous pedestals for starters, Next situate the speakers each in a corner and utilize the room dynamics acoustically as Paul Klipsch had originally intended, as with all the heritage series speakers all you need is two separate corners and the wedges you had under them originally trust me on this you will rediscover those speakers.
Best audiophile RUclips comment I've read.
@@xxxYYZxxx And why use these speakers to listen to that kind of electronic music? Any $200 amplified studio monitors will hit you in the face enough.
@@zorglubmagnus455 The Heresys can play 100+db all damn day w/o breaking a sweat, using any old 50+ w/ch receiver.
I would totally recommend using a tube amplifier for those Klipsch Heresey IV speakers. I have the same speakers in black ash, With a Black Ice Audio F-35 tube amp and a Black Ice Audio SS-X sound stage expander that alows me to boost the bass and expand or shrink the sound stage. I have enough base that the downstairs Neighbor complains often. I do want to add a subwoofer, though. The best part about these speakers is that no matter where you are in your living room they sound amazing. You don't have to sit center stage for these.
To answer the question at 30:18, assuming the drivers behave like a linear non-deforming piston (they don't exactly but it's close enough for small excursions), the volume displaced by one is given by: V=(1/4) h pi d^2, where h is the driver excursion distance, and d is the driver diameter.
Equating this volume with the volume of a second driver, d_2, that will have an excursion of h_2, we can simplify to: (h_2)/h = (d/(d_2))^2.
In other words, the relative displacement of two drivers is equal to the inverse of their relative diameters squared.
In the case of a 12-inch vs a 4-inch driver, this means that the 4-inch driver requires 9 times the excursion of the 12-inch driver to achieve the same volume displaced. Obviously, you could plug in any driver diameters to that formula for quick calculations.
"C" wyrm so what’s the answer? 😃 I’m curious now and geometry is not one of my strong suits
skizzlemane1 Well, using the formula, we can find that a 4-inch driver would need to move 54 mm to displace the same amount of air as a 12-inch driver moving 6 mm.
As for the other sizes,
A 5.25 inch driver would need to move 31.3 mm.
A 6 inch driver would need to move 24 mm.
An 8 inch driver would need to move 13.5 mm.
A 10 inch driver would need to move 8.64 mm
And of course these are all only approximate; the larger the excursion the more error there is in the number, since in reality the driver does not deform perfectly linearly.
Hope that helps!
Originally. the Heresy was intended as a center fill speaker for use with a pair of Klipschorns. As such it was designed for low distortion from the mid-bass up and to let the big folded corner horns do the heavy lifting for the deep bass. The Heresy [I] to III were sealed boxes, acoustic suspension/smallish infinite baffles. The story is that when Paul W. Klipsch was designing this speaker with a direct firing woofer without a bass horn it was heresy, hence the name. Yeah, old dude here.
Thanks!
I predict that when Z hears the Cornwall 4s, the Heresy 4s will be for sale.
I predict Z will need back surgery after getting Klispch Cornwall IV up the stairs.
@@adambrown8867 You know, he leave all the heavy lifting to Pasta...
I believe he'll toss the Klipsch out that window after he hears a Tekton Double Impact or Moab.

Tektons are an incredible value.
However, once you become accustomed to the astonishing detail and transient response of horn tweeters, it's hard to be satisfied with any direct radiator.
You mean moved to Rear channel duty?
So when are the KLIPSCH CORNWALL IV showing up for review?
Might as well go all the way with the klipschorn .
Are you offering to carry them up the stairs for Zeos?
Came to comments to say the same. No reason to go through all the trouble and expense to add subwoofers (to do it right and match the quality of the Heresy, it will take two subs and a DSP or active crossover and multiple amps - as he scratches the surface on) - which is a hole not worth going down and will be a source of endless frustration and constant tweaking for Z. By the time you've properly figured out your subs, you are taking up more physical space and spending more money than if you just bought better speakers from Klipsch. As he said, these are the cheapest Heritage Klipsch speakers. They were originally designed to be a center channel speaker! Yes, they've been redesigned a lot, but these are still Klipsch's bookshelf models. Get the damn full size already. Get the Cornwalls or even better, a pair of Chorus IIs (used - because they don't make them anymore), which replaced the Cornwalls before they brought them back with a re-design.
I have Cornwalls I's with new caps. It's just *chef's kiss*...
Welcome to the Klipsch Heritage family. Took you long enough. But at least you arrived.
It isn't truly Heritage until he covers the fully horn loaded Klipsch Heritage line. Of course, I mean the K-Horn and La Scala. That's where the Heritage series shines, try 1 watt, I dare ya.

you hit the nail on the head I've noticed all the speakers I have owned from klipsch with dual wire post have benefited greatly from removing those cheap jumper clips and bi amping them but hell just removing the clips and replacing them with good wire makes a difference
This might me be the wackiest/greatest review I have yet seen.. It's like all of Zeos' time testing gear has come full circle.. With the same goal we all have and that is, audio bliss. It seems like, for now, he has found it!!
Robinson: They dont need a subwoofer at all
Zeos: TWO SUBWOOFERS! THEY NEED MULTIPLE SUBWOOFERS!
in general all speakers need subs.
They do a solid 40hz in room, for most subs wouldn’t be needed so Robinson’s not wrong, but if you want to listen to dj shadow three Ralph’s or experience leftfields swords in all there glory yep subs are need
Last summer I spent a nice chunk of that time repairing/refurbishing a sansui sp-5500x that I got for pretty cheap. The cross over needed new caps, the woofers needed work before their surrounds were completely gone and the all of the horns were blown. Caps were an easy fix spare the horse glue holding down the old rubicon and the woofer was salvagable even though they used While I was able to find replacement parts for the squawker/tweeter horns I could not find an original replacement part for the super tweeter horn but I found a set of super tweeters that uses the same driver material found in the larger horn and the super tweeter and normal tweeter have matching sound signatures so it worked out far better than I ever anticipated in the end. Anyways I have to agree, there is something to three-ways and large speakers like this. Those drivers simply do not move as much as you expect them to move and having each driver doing less just leads to the whole thing sounding so clean. I can see why klipsch makes these style of speakers still as does JBL in their synthesis line.
Your frequency balance problems when you put them on stands was probably because you put them on stands. That put the horns directly on ear axis, for one, and more importantly, you lost several dB of bass because you were no longer getting floor reinforcement of those frequencies. They're voiced to be on the floor, with all the acoustic effects that has. When you put them up in the air, that's gone.
I love how you talk about your different speakers being different flavors of ice cream WHILE AT THE SAME TIME there's a neon ice cream shop sign outside your apartment in the background.

That's a good analogy ,lots of choices and everyone has their favorite but it's hard to not like them all.
Perhaps the most insane reviewer On-Line? I love it! :-) Keep up the funny and very informativ vd's & stay safe. Cheers from Denmark :-)
this reminds me of my childhood (80s) speaking of vintage my dad had a Marantz receiver with 4 12" Cerwin Vega floor boxes with the orange surrounds, to a kid that was the loudest thing in the world!
I loved the neon ice cream sign in the review. I've learned a lot by watching these videos . I've thanked and blamed Zeos tons of times for my jbl 305s , along with the aune x1, and headphones, and the new pair of Jamo c93 for my home theater, and the micca OoO that just make no sense on how such a small speaker makes such a great noise. Enough rambling me! Thank you for educating me on the complicated world of audio!
Their is pair of these in my parents basement, as wedding present in 1964. They look identical, I wonder if the mice has gotten to them? Still in the original box. Wonder if they are worth anything? 55 years old...
You are an idiot sir:)
GO GET THEM!
Been following reviews for the Heresy IVs for a while and this is the best review so far. Some reviewers said to match these with a tube amp to temper the brightness; Zeo's better, cheaper solution? DSP. Some reviewers have said it's not the best for modern music but good enough bass, and only excellent for the type of music they prefer; Zeo's solution? Cheap dual/sub. Efficiency discrepancy between horns and woofs at high volumes? Bi-amp w/ DSP and subs.
Tells you exactly what you need (or what you don't) for what you want out of these speakers.. even numbers for dsp. All are affordable options too. Great fk'n review.. only criticism is no upside down demo lol. I really need to start saving up for these D:
A tube amp is on my list of things to try. But I want the volume. The Gain. The FFFF.. I will beat these with my magic stick until they are Thor's Hammer.
@@ZReviews Hook those babies up to your Crown. I dare you. I think that you will be happy with the control, and clarity that you get. I have a Crest ProLite 2.0 running my 590's, and a 600 watt Carver/Sunfire pushing an HSU 12" sub, and it kicks major ass. My Klipsch Chorus ll's will be with me until they go to my son in my will.
@@ZReviews IMO the move to make with these speakers is pure "Class A" baby!!! You love the RebelAmp for HPs so get the equivalent for these babies they deserve to be the pretty girls at the ball. Something like First Watt J2, used Pass Labs X250, used Krell, or something similar.
Obviously Z's respects vintage technology. I would love to see a review of the Tannoy Turnberry GR's. Patented in 1947. I own both Tannoy and Klipsch.

What’s the final setup you had here? I’m considering getting a pair of these and want to set them up somewhat similarly. Thanks
. Zeos landed 'kinda in the middle of several different ways to accomplish a better sound here. He really sort of Frankensteined the chain I think, just because that was the equipment he had on hand. I'd be happy to answer some questions 'bout it.

Enjoyed the review, years ago had the predecessor Heresy and had the dealer remove the floor mounts as well ,placed them at ear level and loved them with my Velodyne 15 inch digital sub.had them set up in a 5.1 config for home theater ,had original RF7 and just replaced them with the RF7 |||'s . I know they're big and heavy but after listening to your rave Heresy review would love to hear your take on the RF7 ||| , bad or good , personally I love the way these sound on music and movies .
Enjoy my RF7ii's
The floor reinforces the bass (think of it as a built in corner) and reduce the highs because they're not at ear height beaming at you. I think you created problem three by putting them up in the air.
I like how they sound when they are on the ground with their stock tilted bases. For me, no sub needed in that configuration.
Seeing ice cream sign outside and then he says “ different flavors of ice cream “ synchronicity
Zeos .... .... .... . . its the first time ive heard your voice manner in that level tone/excitement/disbelievement ... good for you !
they look fooking great !
I can't wait to get them back up. I imagine a few months straight of these will calm me down.
Three weeks ago, I received my pandemic speakers, new Cornwall IVs and my sheer joy has been similar to Z's. One of the reasons I chose them was that I could save $1k on the amp. I don't need the subs either. I did raise them up six inches and put them on wheels so that they could be turned depending on the sound stage that I want. 16'x12' room.

It’s nice to see Z reviewing klipsch heritage 👍🏼
a klipsch hereitage line review is incomplete without a tube amp imo though. Tubes and klipsch go hand in hand.
Putting my pair of heresy 1’s on stands and in the corners made a huge difference in soundstage and bass in my living room. They were on the floor and against the wall before and they were uninspiring.
But even in their new position you can still tell exactly where the low frequency cuts out and there’s just nothing below that point.
So unless you’re ok with missing a significant portion of the information in your recordings below the cut off point, you need subs.
But if you’re going to add subs, might as well get Cornwall’s. And if you’re putting Cornwall’s in the corners, you might as well get klipschorns. 🤷🏻♂️ which is what I ended up doing.
Problem is my used klipschorns cost me the same as this new pair of heresy iv’s. Actually less when you factor in the subwoofers and stands.
That’s the problem with klipsch. I love klipsch and have for my whole audiophile career. But the vintage heritage line are so robust and last forever. For me it doesn’t justify spending 10x more on a new pair. If you have the space I recommend used Cornwall’s or klipschorns. La scalas and belles run into the same bass problem as the heresies.
i picked up a pair of unfinished heresy 2,s at good will for $12 a piece grills were screwed on lol they have even less base as your new ones but with a sub they are great sanded them and finished them in dark walnut stain now they look and sound great
If there is a driver balance problem, you cannot fix it by normal biamping. You have to have different gain control for each channel. Using a dsp or AV amp is one solution otherwise you have to use separate gain controls or attenuators for each amp.
Today is the day I've been looking forward to... Z Heresy IV review! I Love my Klipsch Cornwalls; hope you get a pair to review someday!
Me too!
Z! I really like the direction you are going with the Heresy! Are you going to install two more crown and two 15" Subs? Klipsch makes them? The Klipsch guys say it's good to listen to them positioned so the horns cross in front of your ears? Did you consider the Cornwall IV? (short for corner wall ) It sure makes a lot of sound without moving, doesn't it?
What a great review and set up. Not many reviewers out here that do what you do. Thank Z You da Man!
Zeos, you could add a diy horn sub to get more closely matched sensitivity, and serious gut punch capabilities. Once you get hooked on horns, all else pales in comparison if you like to rock, and live for visceral impact.
I love the comments about the Klipsch, I'm also an owner of Klipsch, but I would say if you were interested I would get the SL-15 Cerwin Vega, they do not require subwoofers at all, or stands. If I would put these in a price category they are Klipsch La Scala, but even the La Scalas require a subwoofer. I know this because my friend owns a pair. My SL-15s are only $1000 brand new.
Who else times videos based on cooking wings?!? God bless Zeos! Stay safe all!
Hi my friend love all your videos please can you tell what those round looking crab things are on your window sill are please thank .. and keep the videos coming
Just wait until you raise them up 2 ½ feet. Much better height imaging. I also tried the extreme toe-in idea and that is better than straight ahead or minimal toe-in, in my opinion...way deeper soundstage and even better detail. I put mine up on end tables and I agree with you - can’t live without them. They bring the music to life, ESPECIALLY vocals. Good Lord, the vocals.
Beautiful Veneer. Simple solution. Put a volume control on the horns. You have the "straps", so put a volume control after the speaker and before the horns. Problem Solved. Much simpler and cheaper $$$$$ than a second amp.
You're Welcome.
Now I know what to do when I buy a pair of them. If i really feel the need in my listening conditions.
This is simultaneously insane and awesome.
SUCH A CUTE CAT!! Considering these speakers myself or Forte III. Thinking three Heresy IV to use as LCR channels for Home Theater since they low profile but I am considering alot of different floor standers. Too many good ones available right now is a pain in the ass! Appreciate the great reviews! Did I mention you have an awesome cat?
i have a heresy iis and they are amazing!!! vocals and mids are so up front and smooth
Nice seeing beefier more substantial speakers w/ larger drivers. Z this your best review ever, I hope you do a review of the Cornwall's next, wondering if you'll keep them too. ( Steve Guttenberg have those broken in too) This the most complete, best review I've ever seen for the Heresy's, good job Man .
now they have my attention. it took your review to make me even want to return to looking at these. my brother in law had a pair of these in the 80's and i hated them. he ran them with a old school Pioneer 100w/channel receiver that ran them to incredible sound levels but it was nothing but an assault of mid-range that nearly killed me. their clarity was incredible but there was no full-range sound to them. this could get interesting. thanks Zeos...
What sets you apart from other audio reviewers is that you improvise as your going through the speakers while reviewing... not easy to pull off the way you do... nice work...
I'm debating between those and the Ohm's....hmmmm....if you had to keep one pair, which would it be?
That is a good question!
Hi Zeos! Did you also check out the possibility and the upgrade option from GR Research for the crossovers? Very nice video and interesting approach to drive the mid-highs and lows separately. Perhaps one reason more to check out the xo upgrade from Danny 😉
That's why the PS audio exchange exist they have kits where you cannot rebalance the speakers where you can bring more bass out of them and cut back on the mid and I by her ex exchanging Parts off of the crossover just by changing certain pieces off of the crossover board you can change the efficiency of the speaker and they do sell kits so you can change them up and you won't have that problem anymore and you won't have to run two amps to one speaker
And I have been using their speakers for years and I have not only been using them I have been modifying their crossovers a years to get better sound out of them and there are kits you can buy to change the capacitors the block resistors and the coils on the crossover boards that'll give you more Bass and more highs and mids I know those particular speakers that you have there
Nailed it! I am hearing the same character in my setup and strongly considering stands and adding dual subs
Thank you for your review which helped me soo much after recently purchasing the Heresey 4, and was wery disabopinted AFRET REYING THEM for the firest 4 weeks the sound was thin and whed inreasing the volum was getting more thiner, after seeing your goog review, I placed them higher and adjester the speakers sound on my also new Marantz7013, but I still may be thinking about pre amp, and I 'm not sure if I can do that with connecting my old Onkyo656 with the new Marantz 7013? thank you appriciate it.
Look, not bad for 1.4 cubic feet of dynamic sound. Originally in production from 1957, they rock.
Now that you have the DSP set up, let’s see if you can duplicate or better the sound with DIY. Maybe line array with some lite weight drivers
The JBL L100 which is similar in size also really needs to be elevated beyond the shorty stands they offer. Which may be why JBL classifies them as bookshelf speakers instead of floor standers. Anyway, the surround on the Klipsch is made of treated cloth and is known as an accordion surround. It's very commonly used in high efficiency pro sound drivers. The cabinet for these is now and always has been undersized for a twelve inch driver to produce truly deep bass. But it is not strictly a mid-bass driver as it will play well down into the 50 hertz range which is most certainly in the bass frequencies. However, in an elevated situation such as this you probably will see a dramatic roll off starting around 65 hertz. But as Z said the sound you get in your room will vary. In any event his assessment is accurate. You need a sub. But then to get the best performance from pretty much any speaker that doesn't have multiple large subs built in you need a sub, or two. Yes, really. You think you don't until you try them and then, wow, what a difference. Now, I know a lot of people think bass is the only reason to pay more than sixteen dollars for a speaker and will think these are a rip off. Other folks will fuss about the lack of extension on the Klipsch but then pay five thousand bucks for a pair of bookshelf speakers that roll off below 150 hertz and claim they don't need subs for them. Okay. Truth is these speakers have a lot of competition at three grand. But just as each of these competitors can do something the Klipsch can't. The Klipsch's can do scale, dynamics and realism in a way that I've only heard from one other speaker at the same price point.

Oh! You know, The Forte had a big Brother: The Chorus 15" sub AND 15" passive radiator.Senisivity 110 db
I had a set of 1990 Klipsch Chorus II speakers. Fabulous all of these years. Just lost them to Hurricane Ian storm surge flooding. Will probably replace them with the Klipsch Heresy IV with a similar set-up that Z Review has in this video!
Every time I watch a Z Reviews video and hit blinds are open. I really wonder what people are thinking when they look up and see a guy walking about pointing and yelling at things in a room with GoPro on him.
Good point on the woofers, I think there is some sort of Doppler effect when you try too much bandwidth on drivers.
Did you consider mounting the Klipsches on top of the subwoofers?
Hey Zeo you should review the jbl L100 classic speaker.

Been looking forward to this since I first saw you had them as I have Heresy IIIs, missed 10 minutes of it working out the volume of a cylinder for the 4" driver extension question. It would have to move 54mm FWIW.
CONGRATULATIONS! On acquiring the Heresys
Actually the name says it all ,the second meaning to heresy is "an opinion profoundly at odds with what is generally accepted "as an audiophile speaker which is why some love them while others can't believe someone could love them.
. . . all that is not necessary, my Bra. Utilize a high pass filter between your subs output, and the Heritics, buy it set at 100hz. No freqs below 100 enter the Hereseys . . . the big 12” instrument speaker, then becomes an excellent mid-base/lower-mid driver, with the subs crossing with a 3d order, 18db per octave roll off, doing the down an dirty . . . try it, puts nothing in the signal path . . . you need powered subs, though.
Parts Express sells the filters 😊.
"While my girlfriend weaves baskets"
Oh man I love this video but I gotta know how well can this raised up dual amp approach work with the cheaper end Klipsch speakers. How satisfying can that be for the money?
The bottom tier is the line of powered speakers. Then and now 😉
I've not heard this setup, but this review makes me want to sell my car. Well done Z!
It is rather ironic that many people think that Klipsch speakers sound so 'effing great and there is a whole industry of folks out there making modifications for Klipsch speakers.
Yeah, a tad misleading. People aren't modifying brand new, modern Klipsch. The industry you speak of is there to keep 40+ year old speakers out of the landfill. New crossover, replace a blown driver, not a problem. I get it, some people don't like horns...... Some people love them!
Alot of people don't like the horn speakers but love the look and design of the Klipsch. I know some people see the price and realize with a mod, they could get the sound they want for less than buying a higher end speakers as well. Klipsch makes pretty good cabinets for their price and they're extremely flexible in audio performance.
@@Trogdor204 Perhaps, although GR Research does a lot of modifications on newer Klipsch speakers, but yeah, the Bob Crites upgrades are more for the older ones.
Most are factory replacements with parts that no longer exist from the Klipsch. Some mod the crossover but that's like changing out the ecu in a car not tossing out the engine. The Engine runs just fine with a little tune-up.
redstarwraith Just like a good American muscle sports car. There’s always a bit more you can squeeze out of it. Unless you want Tesla but where is the fun in owning that?
I don't need a subwoofer. I listen to music not bass. Sorry 😢
Have a 1970's pair of Altec Lansing speakers (complete re-build), duel 10" woofers, same design wrinkle paper, turn them up and that mid horn just takes over. What happened to mountain bike, replaced with paintball guns.
You should definitely try the Solaris with them (in you new home I guess). The Solaris is such a great amp. Loved my Yamaha 3000 combo but in a reasonably sized room or with very efficient speakers the Solaris adds so much to the music that makes you emotional. Try it. Seriously. Trust me 😀
Speakers good for Bar & Club music . Drinks at the BARR , perfect
Saw a video where a designer said higher efficiency ( Klipsch law) reduces distortion and you get more sound from less cone excursion. That’s why that huge cone barely moves when rockin
Think of Bruce lee’s three inch punch that sends the guy across the room. The big cone is hitting harder and faster so it doesn’t need a three inch throw... bro
I am interested in high sensitivity speaker (I have 92db German horns) but these are 99db like the Fort III.for an extra grand but the Cornwall IV is 102 so it's like doubling your power.I'd like to have something that could run off a 1 watt amp (LTA's MZ2).Heresy and Cornwall IV need a sub so I am hoping that maybe the Forte which can be run close to front wall even with that 15" well hoping that they update the Forte from a III to IV and get improvements wrought in the Heresy and Cornwall.I wish you could get a pair of Tekton SET15 which can be run off 1 watt.But this was great review though I have to digest the bia-amp option with its presumed degradation of sound unless you have some very expensive analogue x-over.Great Review Zeos
in the 70's and early 80's there were several 12 inch-woofer speakers like that Heresy that were usually placed on 10-15 inches stands and tilted back; i can recall models from Advent, JBL of course, Avid and KLH, to name a few.
These came out in 1957.
I have a set from 1982 and raised them off the floor. I wouldn’t part with them. The box on mine is sealed. However I do have one issue. I think I have a driver going bad. No idea what I may do to fix it. I’m sure original parts aren’t cheap. I do want a Rel Sub and Marantz 1200 to pair with them.
If one driver goes you would need to change both because they would never match after 37 years of use.
Z Reviews thanks for the answer
As the owner of a set of original Heresys from the 80s I can assure you that the speaker has always been a 3 way.
Between the Heresy's and the Forte III's I'm not sure which I will take, great review as always, now I have to watch the Forte review again. :)
The forte shared a lot of similar benefits and issues. Need to be a TOUCH higher and need a sub for the REALLY low stuff.
@@ZReviews A sub with the Fortes? Really man?
Mine sound great from on the floor. The key is to sit far enough away. 12 feet minimum. I'm at 16 feet and it is perfect - no sub needed.
I'm thinking about buying a pair of the Fives for my living room/movie setup, which subwoofer(s) do you recommend I should pair with them? (under £800.00)
Large woofers are the secret to star spangled awesome sauce! Why? Because beaming my friends! It's actually a good thing for frequencies below 1000khz. And big woofers help a lot to focus frequencies below 500hz. They won't achieve cardioid bass by any means, but they're much better than having 2 five inch woofers. Honestly, MTM designs have never made any sense to me. The center to center distance is never close enough to avoid comb filtering in the mid range (intermodulation distortion), plus they spread too much sound to all the side walls. MTM trades everything for a symmetrical vertical lobing pattern. Smh, It's so bloody stupid. It's a total failure, and I'd be glad if they chuck all D'Appolitos into the sea (not referring to center channels).
Use small woofers and too much sound is hitting the side walls and floor and ceiling. It creates a muddied sound and is unclear.
Small speaker drivers are best for very large rooms, or heavily treated rooms, because they're able to spread the sound far and wide. Oddly though, they lack the ability to move much air which won't fill a large room. So stacking small drivers in a line array configuration is sometimes good for large rooms.
Physics affecting audio is quite peculiar, and the general public is oh so very lost and confused.
If you have a small to medium room, a large 10 to 12 inch woofer which doesn't have much excursion is your secret weapon to achieve better clarity and sound staging. Small mid-range drivers are also a poor design choice for most homes. Go with a 6.5 inch (not a 4 inch) and harsh frequencies from 2 to 4khz won't be bouncing all around the room-- depending where you set your crossover point.
Cardioid bass is the goal, along with a good directivity index result, especially for most home environments.
Here's a good setup for increased sound staging, clarity, and decreased listening fatigue.
A 3 way with a subwoofer.
One 10 or 12 inch HiFi driver, just like the heresy's. High excursion not required. We want it to be able to play down to 60hz with ease, but below that is the job of the sub woofer! Possibly use 2 eight or nine inch woofers.
Then a 6.5 inch mid range. Crossover region ~250 to ~4khz. Yes, moving the crossover point an octave from either of these points would still be fine and understandable. But those are general boundaries.
A ~1 inch tweeter.
And the sub.
I'm not a fan of compression drivers. What's the point? Most people don't listen at high enough volumes to have a driver which typically doesn't measure as well.
If going for a 2 way configuration. Consider 2 seven or eight inch drivers, and a ~1 inch tweeter. Focus on HiFi drivers without massive excursion or crazy bass specs. You want mid bass and mid range clarity. The sub can always pick up the low end. The crossover point will be ~2,000.
Older speaker designs had a lot going for them and now with the better drivers of today, they've been perfected.
Granted, they don't look like slim sexy towers. That's the only drawback.
looking at buying a pair and bi wiring them with my McIntosh ma6900 to the top section and an mc300 to the bottom n wonder if that ill work to keep up with the horns
Great review 👍
Just bought a Marantz nr1200 and seriously considering adding these 4's to my room.
Finish may just be sanding sealer without a true hard finish coat on top. That's a cost saving thing. Sanding sealer is much easier to buff out than a harder finish.
I still have my original 1981 Klipsch La Scala's and they still Kick A**!!
Steven I too have my original 1980 La Scala’s. They were dormant for over 30 years and this “new reality” has me at home enjoying them once again
I bought Heresy III based on Gutenberg's review back then and no regrets. I got them for $1800/pr, seems like bargain. I live in a small place so I don't even have room for a sub or miss one too much, though I'm sure it'd be even better. I'd love to try the H IV
Hi! I tried to search through the commits and didn't find this question yet. However, I noticed that you were very impressed with the SVS Ultra bookshelf speakers. How do they compare to the Heresey IV's?
He bought them is your answer.
“Eight watts would kill ya” Lol 😁
I was watching another vid about Klipsch and they stated that the Heresy was originally designed to be a center channel speaker to the Klipschorns. That explains why they don't need to go deep. The speakers that need to be looked at are the Fortes as they were designed to be stereo speakers.
Saw this in 2023. Everything is peachy, Past Zeos. Everything is peachy. Nothing is wrong, no problems at all. *sob*
I love the idea of legacy klipsch dpeakers. BUT everytime i see a review of one or the last time i spent the day at their engineering facility, i want to build new cabinets so that the driver acoustic centers are lined up and adjust the crossovers to take advantage of the increase in coherencey. After spending years designing pro sounds systems using speakers with woofers misaligned with the horns, i learned to digitally time align the drivers. The increase in coherence was revalatory.
I was playing with delay between the horns and the woofer. Any pointers?
@@ZReviews it depends on how you are doing it. Are you using the klipsch crossover or using a dsp for the crossover? The klipsch crossover parts are chosen to try to offset the time alignment by altering phase. When using the stock crossover, get a dsp with open architecture software. You split the signal, cross h.f., up, the l.f. down and add a delay to the shorter depth driver . Then recombine the signals. Use the steepest slope available. Slide the crossover points up and down together until you get as little frequecy response changes as possible. Measure physical offset and start with that for a time delay. Use a time alignment function on test gear like from parts express or dual FFT analyzer to fine tune the delay. Then adjust one crossover point, slope etc. to flattenn response.
