- CHR TOWER PART 1
In this video I report the first steps to build the CHR Towers. Intro, Main Idea, Goals, Test Boxes, FRD and ZMA files extraction, Material Selection.
The CHR Towers are a fantastic pair of powerful audio, low bass, high quality speakers. Made in Walnut Hardwood mixed with Euro-Ply and veneer this design relies on the Markaudio CHR-90 Full-range and the SB Acoustics SB15MFC30-8 Woofer. This is a two way speaker box that impresses by its power, SPL and High Fidelity performance, even using 5" woofer drivers and full-range drivers.

Great content! You have a eye for good looking speakers, and I can tell you are fussy which I appreciate! How bout building a nice down firing Subwoofer with granite base. I have a great design in my head that I think would look fantastic! Kinda like how the current Bose subwoofer looks. 🔈👍🏻
That’s right! It’s a good idea! I might use some concrete then. I like the look! Thanks!!
I like the keep moving forward attitude. You make the videos fun.
Thank’s for the input my friend!!
I love your truck! It earned that patina over many years! Like you! 😂 (Me too!👴) Keep posting videos!!
My wife often tells me I need adult supervision when visiting my hobby stores....
Hahah! That’s right man. We all need that supervision! I’m glad you like the videos!! Thanks for watching.
"Can't let me go to the hardwood store by myself... " 😂😂 no words more true
Hahaha! Right? I love it!!! Take care.
Hey brother, l just stumbled across this channel and am really enjoying it! I've been building speakers on and off since the early 2000's and am ready for my next project. I learned my way into DIY via the guidance of guys like Paul Carmody and Jeff Bagby. I played with full range speakers early on and was just so disappointed with the outcome. I would always have major spikes anywhere between 800Hz to 3KHz that just couldn't be tamed regardless of how much filter you threw at it. It looks like technology has come a long way. If you're ready to share plans I'd love to make this my next project. I look forward to hearing from you! I'll do you proud!
Hey Greg. Thanks for the input my friend. I really wanna upload the designs one day. For now there are some info on the video description. Check it out.
Jay, I love this story. These listening bars are beginning to pop up in Australia. I love South Korea having been fortunate to visit several times. I got the same emotional response listening to Pitt and Giblin speakers made in Tasmania, Australia. At some volume levels it hits you in your gut 3:55 and the emotions rise up. Happy days.
Hey Peter!! That’s right man! At the end that’s what we are here for right? It feels good to hear good audio!! Love it.

Hi Bernado is it? Somehow this comment was meant to go on a Jay Iyago video about vintage RCA Speakers in South Korea. LOL.
@@peterrabbitwarren strange! But no worries!

Awesome video again Bernardo! Looking forward to part 2
Thanks Adam! Coming soon.
Always enjoy these.
Thanks Robert!
Lookin goooood!!! Can’t wait for part 2!
Yeah!! Coming soon. Thanks
Great video as always, they look awesome, the more you build the better you can't have enough.
That’s right Nicholas!! Working on video 2 now! Those speakers are my faves at the moment!
excellent!
Waiting for video # 2
Thanks Arturo!! I’m working on video 2 now! Let’s do it!!
@Sonnora Design When You size the internal volume of the speaker do you substract the volume of the damping material you installed in them? Thanks
Hey Norbert. No I don’t. Just solid pieces like the braces and whatever takes volume.
I'd like to see you do something with either open baffle or horns. Or both together
Horns are cool! I’m working on a Más’s loaded transmission line at this time!
HAPPY NEW YEAR.
Happy New Year!! New projects coming.
I dig the ole Ford!
Haha! Right? It’s running. 1971
Can you describe the crossover you used? Thanks for the video.
Hello Mitchell. It’s a 1st order crossover. Pretty simple and the slopes are pretty smooth. Consist of a capacitor and a coil, you can get the schematics in the video.
I so want to build these speakers! I have a problem though, the Markaudio CHR line is no longer available in the U.S., as far as I can tell, since Madisound is permanetly closed. That wouldn't be nearly the issue if I knew how to build my own x-overs, but I dont. Are there, or do you have different speaker options that you have worked out?
Ops. Is Madisound closed? Website is working for me. They show the CHR still but maybe CHP would work well. I’d need the drivers to make the crossover. I have another design coming up which is the CHR 3 way. With super tweeter and 10 inch subwoofer on the side, maybe you could wait a bit.
Waiting for part 2🎉
It’s up!! Check it out!
That's why I used old furniture I found for the hard maple for speaker boxes. It's a lot of work sanding the finish off but it's worth it in the end. I building a new pair out of oak right now but they are heavy. 😂
Oak is nice! Pretty hard! You have a new design then? Hope it works well. Let me know how does it go.
@@sonnoradesign Thanks I will. They are.5" MDF and I used flooring adhesive and troweled it on and glued.75 " oak hard wood flooring I had left over from a job. They are just basic old school floor standing speakers 10" woofers like the 1970s style big heavy monsters.. You are right... It is a lot of fun !!!!! 😂 I will keep you posted. I made a short story so if you want to see the maple ones I built with the TCP 4 woofers.
That’s cool man. Sure I wanna check that!
Buddy your design attributes are awesome. Would be wonderful to see your execution of a powerful boombox one box with trolley that can be used on open terrace
Thanks Anand! I’ll make more boomboxes in the future. Not sure if I’d add the trolley but I get the idea!!
Ola, tudo bem? Sou do Brasil e admiro muito seu trabalho.
parabens pelos videos, eles me incentivaram muito, e em breve irei fabricar minhas caixas de som tambem.
por acaso voce teria videos falando da eletronica e corssover que utilizar em seus projetos?
Obrigado por compartilhar seu conhecimento e experiencia.
Fala Felipe. Obrigado por participar. Que bom que tem te incentivado. É muito divertido mesmo. Aínda não fiz vídeo de crossover mas vc não foi o único a mencionar! Quem sabe em breve!
Let me understand, because my poor English, but does it means no need high frequency speaker (twitter), some videos use three kind of speakers: two for subwoofer, one mid, one high
En esto caso el parlante dorado es un full range, el toca frecuencia baja e alta al mismo tiempo.
Hey my friend. I was looking at building tmm and mtm and I was reading about logging or combing with having the same drivers at the same frequency and I was wondering how you got rid of the issue
Hey There! It might happen. I usually work on the crossovers to check the phase and possible cancelling. I’m working on a new crossover for those towers for a more flat response. If they play without the crossovers the combing is visible on the graph and this configuration is challenging cause the drivers are similar and play the same frequency. I might post the new crossovers soon. Let me know if you need help with those.
@@sonnoradesign ok thanks I appreciate it. I just was watching a video about combing and I thought I would just ask thanks again
@@BostonMike68 sure!!
@@sonnoradesign I just scored a ton of free 🍁 hard maple.
@@BostonMike68 Check the Halcyon kit at Madisound. It’s the same concept with a series crossover. There is the whole design development on the link.
A hornspeaker would Be Nice to see🤔 Great vids btw!
Yeah! Thanks! I wanna work with the horns. Maybe some other fullrange drivers….
Hi, I'm about amplifire and I can see on your's video you bulit one. Will the video appear on you chanel I believe that's efficent and sounds amazing
That’s right. I made that. It’s an ICE power with a tube pre amp. I have one video on building a pre and power amp. Take a look at the Channel. It’s there.
@@sonnoradesign I saw your video of building the pre-amp but in your videos you’re using different one and I was curious and thought that you make new one with DSP or something
@@Chili_fpv mini dsp is a good one. I made one with tube pre amp and mini dsp once! Fun
The silver flute are probably the better driver in terms of low-end performance with a natural timbre. Maybe if you decide to revisit this theme again in the future, you can see how those work for you. I also just think that their satin, silvery-grey look is very sophisticated. Dayton Audio's Esoteric and Epique lines of speaker drivers are both beautiful and impressive in quality and performance. A shame they're quite pricey and blow the budget.
That’s right! They are good drivers but more into the high $$!! I’ve seen the silver flute but never tested, I might give it a try.
@@sonnoradesign They feature cast aluminum baskets and a treated paper and wool cone. Their sound quality is good and trends to the warm side and they have an impressive operating frequency range, particularly in the low end. Cross them over a little bit low, around 2kHz and you'll avoid any breakup or beaming entirely, though they can be crossed over higher if you require it. I'd recommend trying to design around the 8" model both for the improved bass response, but also because it will require less effort to find comparably sensitive tweeters. If I remember correctly, the 8" driver is around 91dB, which is right in line with most commonly available tweeters and won't require much work in the crossover to balance the sensitivity. I find that they pair particularly well with silk tweeters, with my personal preference being for the dual ring radiator ones from VIFA or Peerless, but conventional silk dome tweeters are also perfectly fine. I would avoid titanium dome tweeters, and probably aluminum dome tweeters as well. AMT tweeters are also not ideally suited for the same reason: they're too crisp and sharp for the warmth of those woofers, so they're not a great match. Beryllium or ceramic dome tweeters are probably acceptable, as they have fewer resonance problems, but silk is really where it's at if you want the best bang for your buck. Check AliExpress for VIFA XT25 and you'll get quite a good selection with some being very reasonably priced for a pair with oversized magnets.
@@mndlessdrwer hey! That sounds good. I really have to give those a try. People seem to like it a lot! I have a couple of pairs of the peerless XT25. I really like them and used it before. Maybe a MTM with 2 x 8”?! I’ll add to the most desire project list. Hehe
@@sonnoradesign That seems like a good way to build some pretty epic home theater towers. You really can't get the effortless impact you need from home theater speakers without raw volumetric displacement and a pair of 8" woofers per tower is a great entry point into that level of air movement. Should do great with music as well, though you'll have to do a little bit of tuning work to balance the SPL of the woofers and the single tweeter. A 4 ohm neodymium XT25 and a pair of 8ohm Silver Flute 8" woofers should be close enough that it won't require much extra attenuation. Obviously it'll be up to you at the end, since you have way more experience than I do at designing speaker and crossover networks. I would try to see if a rear-ported design could be avoided unless you have the space to really pull them out from the rear wall, since they're going to move quite a good amount of air through their ports and the room gain from speaker placement should be rather exaggerated.
@@mndlessdrwer sounds good! The problem is always integrating the tweeter with large drivers because of the early cone break up. But I’d thought about an 8” project. I really like speakers that move a lot of air!
Good Job my bro , hay caramba
Ai Caramba! Thanks Bro!
How to make the best speakers I heard:
Make speakers similar to the speakers in this video...but don't have the FR driver in the box (and obviously you will have to make another crossover). Have the FR driver on top of the box @ about 45°. You can experiment with the angle. And here is a great option...
Get rid of the dust cap so there are no enclosed air spaces on the FR driver (or buy phase plug drivers, with the stationary phase plug). Now, w ith a razer blade or SHARP hobby knife, slit the cone like 8 mm long and right through, all around, with 4mm gaps that are not cut. Do it about 5mm out from the start of the cone near the center. Repeat on the dust cap (if you refuse to get rid of it). For the best treble you ever heard! Mine are $9 FR drivers 5" diameter and they SPARKLE with this mod! They are dipole with the cleanest med you heard! You can blend the med from the woofer to the FR driver so it won't sound "lean". You can control the lean and round sound ratio to get great medrange! If you do all of this, you might have a dipole heaven, holographic soundstage off the scale (like I have).They sound like panel speakers. 😅
Excellente
Thank you!!!
Modular construction Fruit Cake, like Wilson audio. Avoid the bass drivers shaking the Mark driver around, especially laterally. Minimize Doppler, intermod, etc. I use polypropylene bearings.
Can have a dramatic effect on spatial behavior. Put an accelerometer next to the Mark 9 on this build and witness the horrifying results.
Thanks Dave!!
I love to try to design my own designs but you nailed it with these and I might have to borrow your design if you don't mind.
Sure! Just do it. I’m upgrading the crossovers, so I might post it soon.
@@sonnoradesign I been looking at the silver flutes from Madison sound. They are inexpensive but look really good. I don't know if you have ever tried them. But I'm looking forward to a video from you. It inspires me and they are funny 🤣
@@BostonMike68 thanks man!! Yup, people like the silver flutes and they are affordable. I’ll have to give it a try at some point. I’ve been using SB’s now and they are really solid drivers.
@@sonnoradesignI looked at the graf for the silver flutes and they look like they just drop off at 5000 and I wondered if they even needed a crossover and I found out a lot of people just run them without anything . I'm going to give them a go . I will lyk if I like them
@@BostonMike68 wow!! That’s a good thing!! I didn’t have the chance to check them yet. New video coming soon.
Cool
2 of 8R woofer then parallel to 4R?
Right. 4 ohms at the end.
Can i change to CHP90?
I’d say yes but you might have a slightly different curve then. I’m using the fullrange with no filter now. I only have a 2nd order for the woofers.
Please part 2
Link on the description! Thanks for watching Eyam!
Allllllllll riiiiiggght guys, those speakers look gorgeous and sexy!!!!
Thanks!! You getta listen to them. Sounds really good! Allll right!!!
@@sonnoradesign looking forward to part 2 video. What does your elephant think 🤔
@@incarsound Chandler is so excited! Hah
Can't wait to Video Number Zwo (Zwo=Two), i like your standpoint: (make small ones not to big, efficient) i love it! Because it is small enough our "Lebensabschnittsgefährte" (Stage of life patner)
like it our than the big one! The like sound but no technical design. So make it small!
I doesn't know your final design use you the SB13..... or SB15....... ? but both look pretty, only what i doesnt understand you use 4 ohm on bass and 8 ohm on twetter, what is a little bit strange. but i know you have already the solution.
And i really love your attidude! Your standpoint, and make it 4 Ohms! I hate these amplifiers manufactors that make only 8 ohms! i want 4! i want want power!
And one tip! for another design or inspiration!
Look for the RFT BR25, BR26, BR25E all the same only the design is different! These are boxes from the GDR, east german. you can get them for "worked" in worked status for around 200 till 400 euros but i think, i have one! and i'm drive it with old nad amplifiers like 3045 or 3140 they sound amazing! realy amazing!
I know if a speaker is shitone or have it in seconds, i have two tracks to test!
Hell Bells to check the bell the bass! And Should i stay go or should i stay from kylie minogue to check can make the speackers sex? SEX? Can the sound sound like minogue penetrate there tongue my eardrum?
and a br25 can to that!
greetings from germany
Hey man!! Thanks for watching and all the info! I ended up with the SB15 and they sound pretty well. Loved the result. I’m making a new playlist with my test songs soon! Keep in touch!
Where is part 2??
Here it is my friend!!
You ask to much
Thanks for the input Larry!!
