Anyone doing home theater needs to see these videos. A wealth of information.
I freaking love Anthony. This guy is truly an experienced gentlemen.
He is quick thinking (knowledge and experience) and I can tell he is rushing through and displaying the most information he can for the time period he has and not make it to “physics” talk and I know enough that there are some many aspects for general so just to be able to explain to follow as close as you can to a model. It’s awesome.
I freaking love this guy. Thank you Audioholics for getting him on the team with his knowledge.
I really really want to hire him (but I feel like I couldn’t afford him)or just apprentice him for a year or more or just apprentice. Hire me please.
Anyway, at the least - thank you so much to be able to hear his voice speak on it.
Thank you so much for this series guys, I've been waiting 50 yrs for this level of knowledge on speaker setup and especially room nodes and sub information, absolutely awesome.
This is EPIC! This is the gold standard of bass information. I definitely will be watching this again, and taking notes.
I really appreciate you guys doing these for us!
Another home run!! These episodes are amazing! I’m in the process of redoing my theater space using these methods.
Friday morning…the advantages of working remotely. I can now dedicate my first couple hours to things that matter, like better understanding low end response in my room rather than dealing with pesky help desk type emails. Irresponsible? Yes indeed. Loving every second of it? Absolutely.
3 Questions:
1. Wouldn't you get phase issues in different parts of the room because if the time difference between the subs and your ears, and if not, why?
2. Would the ultimate be 8 woofers, 4 on the floor corners and 4 in the ceiling corners?
3. Does sub orientation matter, up and down the room, facing the width, or have them all facing the centre of the room on the diagonal?
Thank you! Thank you! Can’t wait for part 3.
This is by far the best video on base optimization I've seen yet. Not to diminish any of your older videos, but this talk and this awesome presentation by Anthony was the most informative for me, I really did learn useful things here. Even though I'm not going for multiple subs. Thank you very much, Anthony! You're a great speaker and presenter.
I had an idea for the person who asked the last question It would require quite a bit of luck but I have had times where I used LFE+Mains to deal with issues when I couldn’t move the subs to find any better placement especially when the mains can handle some lower end. It requires a little bit more time adjusting phase alignment and EQ but can be done that way sometimes.
awesome video! "are you guys to go on 5 more minutes?", "yeah". 25 minutes later, "ok thats it"
Another great session, thanks guys! The riser doubling as a bass absorber is a great tip! I will be making use of that for sure!
I am old enough to remember the mid-70's Sensurround and the mind boggling bass that system produced (120DB 15- 30 HZ) so when I put together my home theatre sound system that was my inspiration. Therefore, I am surrounded by subs, a left and right LFE, a center sub, and a left and right sub for the surrounds in the back corners. I get nauseating amounts of bass this way and you'd be surprised how much bass is in the surround tracks. I bought the Midway Bluray which has the Sensurround tones and it was pretty darn close to the theatre experience (though not 120 DB!).
I have a big room. Running all channels at full. Loving it. Almost perfect timing, effects slam in the listener :D + ofc. 2x18, 2x13 and 2x12. Cornerloading is my preference - eliminates a lot of nulls. All 4 corners.
I've been going about all of this with raw horsepower. Thousands of watts and 14, 18" subs later, the output is insane and smooth but I love love LOVE that this amount of information is now available because as good as things are, they can always be better. Having this level of knowledge to reference shows me how I can get to that next level!
Budget audiophile running 14 subwoofers 😆
@@fumpt It's a big ol space . . .gotta pressurize it a ton if you want 10Hz above 115dB!
Maybe everybody else can chime in, but personally, the longer the better. I'd listen to a 4hr one of these no problem.
But it nice to have the breaks to let it all set and be ready to expand on it with the next session!
Yeah!!! JL Audio and RBH on all my cars!
JL Audio is the KING of car audio.
RBH in my theater.
Amazing videos. Been my Friday morning routine and I’ve learned so much. When we’re talking subs in the corner, how in the corner are we talking? All but touching the walls?
I can’t thank y’all enough.. y’all ROCK
@34:50 So if I'm understanding correctly you want flexibility on the internal side of the theater walls and mass/rigidity on the outer skin of the walls preferably decoupled with insulation between?
So an ideal wall would be double ⅝" fire code drywall or soundproofing drywall with green glue and mlv and on the inside just plain ½" drywall on hat channel with a double wall construction, 12 or 16 on center for exterior and 24 on center interior, insulate both with air gap between
Damn! Inspirational and excellent information!
I'm gonna make a use of it. Thanks!
I think the majority of ''Home Theatre's' these days are in the living room. I know I went from a dedicated room down to the living room then to another home where I no longer have the option. Considering how many people watch content on phones and tablets these days a living room 'Home Theatre' is a step up. Point being, it would be good idea to also try to address situations for the common man. I also think more AV receivers are sold for living rooms vs dedicated rooms, perhaps I'm wrong.
2 years later: @7:58 Yeah, quebec here!!
This is my version of that old show Cheers! Love it.
great information,thank you.
I love this video. I'm wondering what 8 subs would do, and how would you place that many subs?
Are 4 8” subwoofers better than two 12” if placed on all corners. Do we loose any output level?
I think whenever the SPL is discussed (especially for very low frequencies) the dB plot label on graphs (and maybe stated verbally ) should be more specific (e.g. dBA, flat, dBC, etc) as the layman may be confused. Great talk and thanks. GG
It's dBZ, which is unweighted. All of the other weightings you mentioned as an example apply heavy negative corrections at bass frequencies, in the order of 10 dB.
Great video guys. Is there a recipe for making an absorber inside the riser? Perhaps it would be great to have a video on this.
I’m running pure copper speaker wire in two home theaters in this house!
Quick question for anyone knowledgeable on YPAO;
One of three subs in my system is a 15” klipsch utilizing their wireless connection. When I run YPAO it judges the distance at 65’ actual distance is 12’
Should I leave it set to 65’ because it’s compensating for the delay or set distance to the actual 12 feet?
Yes, it is due to the delay.
Hi guys. If you want to have a good bass , clean and loud in every corner of the room, you should learn about single bass array or double bass array. You would have good bass with 12” subs.
Does Anthony offer a service where you would send in the dimensions of your room (with pictures) and what equipment you are using and he would cook up a solution?
Those dual 13" JL's retail here in Canada for $26,000.
Hello Anthony from Quebec! thank you for sharing your knowledge!
52:25 He's saying NOT to connect your sub to the sub out or the . 1 channel of the receiver? What? Please clarify.
I took a look at the THX site tool, and also looking at 18:20, don't all these depend also where u place the sub? I would think the location of standing waves would significantly shift just by moving the sub/speaker, no?
Using ashly protea 4.8 myself, awesome stuff :) my question is what about vertical placement of the subs? is it worth to put one sub near the ceiling if using 3-4 subs? I use jbl jrx225 mains standing on a sub so I can put another sub on top of the jbl and it will be almost touching the ceiling 🙃
Your wife must be an angel
So basically just start with four 12s one in each corner then just keep stacking whenever an upgrade is possible, 3-4 12” drivers in each corner should be enough for most rooms.
small and hidden suppwofer :) Which is a small good subwoofer which work pretty well for use 4 subwoofer?? i wantet to buy the XTZ 12.17 Edge, but i think its to big if i use 4.
UNBELIEVABLE INFORMATION!!! Thanks soooo much for the knowledge BUT I still don't have good bass at every seat in my theater. SO FREAKIN FRUSTRATING!! :-(
Story: I have been playing with audio gear for more than 30yrs, and recently I moved into house with a theatre room, with what must have to be the absolute most perfect dimensions for the worlds worst standing wave issue, no matter what I did, no matter how big the sub, no matter what EQ system I used, anywhere but 1 meter from any wall had all the bass and charm of a tweeter in a cardboard box, its been totally disgusting to listen too, have tried Bass traps and sound damping, heavy curtains..... nothing worked, had two subs, tried them apart, together, next to the listening area, under the cabinet, on the cabinet, firing up, firing down...., then I watch this video, and I see all the confusing math and calculations, and I almost stopped watching, then he says, the easiest fix is use 4 subs, 1 in each corner, this is the only thing I didn't try, and reason being, is most people are stretching the budget to buy 1, little own 2 quality subs, so I thought, I'm not spending big $$ to test this theory, so I went and hunted down 4 identical of the cheapest crap subs I could find, had to drive all over my city to get them, but in the end, I paid between $59 and $129 each :) I set them up in the corners, turned off all EQ settings, made sure everything was flat, levels were identical, and fired them up, well f&^%%*%k me, blew me away, those 4 El Cheapo's destroy my big boy subs, and now there is a huge bubble in the middle of the room where all the bass and energy is, and when I move near the walls and corners, they now sound like a tweeter in card board box, and I find there is less bass leaking out of the theatre room, unfriggenbeleivable!, so after wasting thousands, I fix it with $250 worth of second hand junk, I don't actually need anything more now, as those four are gut wrenching, Anthony, your a bloody legend.
How do we get your professional services ? Is there any commercial model in place ?
By the way I have that same microphone. The Aston Orgin is a great mic.
Yea I'm loving this mic. thanks.
I have a 30x12 long living room because I had to duplex and I took the center wall out so getting my sound rate is going to be interesting
Right*
And keep in mind my technology skills are basically zero! Lmbo
Two things I forgot to mention Florida ceiling is seven and a half feet high and I have two chimney stacks in the living room
You mention the minidsp can be used to integrate 4 subs from a single out from an AVR and that delay will help integrate them but isn't the delay meant to be to the mains to delay the speakers to slow down to meet the lagging subwoofers which have the inherent delay. Or are we talking about delay between the 4 subs?
Primarily the delay between the subs but you also need to get the 4 subs tike aligned with the mains too.
Great video
I have 4 of the Definitive Technology towers & 1 center channel each with a small powered amp and 1 Super Cube. Does this help with the dead spaces and what are the down sides?
I am a novice and I appreciate any guidance.
Vern
Us In an Atmos setup including two subs and full range LRC speakers, what would be the best speaker/ sub placement to start with. Can LRC be placed to cancel out rooom modes in combination with two dedicated subs?
what about two woofers in the back?
Where do the Golden Cube formulae come into play with regards to this, when building a room ?
I have a pb4000 and my plan was to get a 2nd in the near future but this pandemic and health issues won't let that come to fruition any time soon what to do? My living room is about 20 feet wide and 10 feet long basically almost a perfect rectangle were should I have my TV placed at? And 1 subwoofer
Hey love the videos got a question I have 4 sony ssc5 I'm purchased scs pb1000 sub in looking for a receiver in the 500$range in looking at the Yamaha 686 7.2 what do you think ?
Your videos are great! Though I am now confused about whether or not I should run LFE to my four subs? I am going to run four single subwoofer cables in my walls to four different locations (for four subs). Is this the proper thing to do?
Who is hitting dislike for these awesome videos !!!!
The Nulls

@@stevelovesgod lol 😂
Great video guys question I have one power sub and the other is a slave sub what is the best way to place my 2 subs?
Hey there, '4 is best' - does that mean having 5 is bad because it makes the number of subs uneven?
Good question.
No think of it like anything over 4 is overkill. If 1 sub is 100% and 2 is 200% better 4 might be %250 better and 5 might be 260%. I just made those numbers up but it should illustrate the point. Another way of wording it would be anything over 4 and you're at the point of diminishing returns and it would have been better to invest that money somewhere else or into better subs.
@@TylerStout cheers mate. Already have the subs from other project so I'll work them all in or take one out if no discernible benefit
@@BradleyAshley Theirs no set in stone limits to the number of subs in a room and given room size and sub size one may need more then just 4 subs to properly/fully load the room... near the end Don mentions working on the biggest theatre room he's ever done (4th largest home in America) and how he plans to use 8 subs in the large theatre room... Anthony jokingly states he'll likely need more like 16 subs, which was tongue in cheek but also truthful as Don agreed he wanted to go further but ran into restrictions.
If desired one could do 8 subs in any room, just by stacking 2 subs in each corner... 4 has become the optimum number because thats that amount of corners/walls in a square/rectangular room and based on the average/typical room size/listening environment, 4 subs is all thats needed... in most cases, but thats not to say outliers dont exist... for ex. with a extra wide or extra long room, maybe you'd need the 4 corner subs, plus mid wall subs on the sides and or rear... which I assume is the approach Don will be taking in his large theatre job, he didnt mention specific details just that he plans to use 8 subs which im guessing means placement of 4 corner subs and 4 mid wall subs...
In your case since you already have the 5 subs you may as well experiment and attempt to integrate them all into your system... Im guessing a good starting point for placement of 5 subs, would be 4 corner subs and one sub mid rear wall.
How do you model a rectangular room where one end is the kitchen/kitchenette based on open concept?
you can't. It's a super room at that point.
I only got one word: YouGuysAreJustSimplyUnbelieavblyF%@CrazyAmazing. Thx a lot for making this happen Gene 😎
This is like having access to the goldmine of audio info 🥳
I am working now with 4 Audio Physic Rhea II subwoofers and Trinnov Amethyst in a pure stereo setup .... it’s about the most fun I ever had 🤣
How does owning def techs sts with built in subwoofers change the equation? Or does it?
Does it help or hurt to go from 2 to 3 subwoofers?
Bad ass video 👍
I have knee walls in my room. How do I calculate for this?
Can 3 subs be done or is even number of 2 or 4 preferred?
May your success always be, and your sound be abundant
Interested friends can check out our Home Studio Microphone comparison videos. Stay with the music.............
Is H10xW20xL25 size is good for dedicated HT Room? Need advice..
Since your height can be divided by the width I guess not. He talks about this at 13:32.
@@Raritytuber so how much the height should be since i can't change the room size. Is 9ft suitable?
One sub in each corner = no damping in corners ?
Good question.
What is the best for dual subs, 1/4 width on the front wall? or 1/2 wall on the front and back?
Experimentation is the name of the game, both placements are proven to work but one will likely be more optimized in your room environment then the other, not to mention that one placement will likely be more aesthetically pleasing to you then the other.
Your best bet is taking REW measurements which will help you see whats happening in the room that your ears cant.
Can't wait to be in a room with some people so that I can repeat this and sound clever
Nice work, friend, can we cooperate???
The biggest and most powerful sub I ever had in my theater provided terrible bass...multiple 8 inch subs are far better. With the big powerful sub, I could hear it really well in other rooms, just not the theater room...it was literally too powerful for that room.
Please, for the love of God and for your channel, announce or notify the guest when he has problems with the Internet/Sound...
3 hours of talking bass over these three video!! Amazing!! However I don’t see Don with much input?!
Don mentions at the very end of the video that integrators like himself, usually pay for these CEDIA level classes. So I figure he came to learn and to meet and interact with the instructor.
Don Dunn as debonair as ever.
Don Dunn head reveal
Anthony Grimani is making Don Dunn look like an amateur tweaker with his camera adjusting, off screen fiddling, inappropriate response to Gene and inability to just work himself into the mood and flow of the show. Most likely, it’s his enormous ego that’s responsible for his off putting behavior, and not an actual drug problem. But it doesn’t matter, he’s super slimy either way and his stimulant (nobody acts like that without being higher than a kite on SOMETHING) based schtick has suddenly gotten old. And his absolute amateursm in front of a camera is only worsened by his erratic behavior and inability to focus when he’s not the center of attention. Really not a good look for Audioholics.
Anthony, you believe in sound travelling in straight lines, the earth is not flat any longer. Don't compare sound to light. I take it you are not an engineer.
What is your point? At no time during these sessions are there any references to low frequencies propagating in straight lines.
