Late to this party…just wanted to thank you for confirming what I’ve been experiencing with zero baffle. You have a tremendous amount of experience and knowledge compared to myself. Good luck to you!
The best baffle is no baffle. Took you a while to get here, but welcome to the club. Your bass is still subject to distortion, but it is better than a lot of other methods being used.
In many years I thought I had seen everything in hi fi .. but this is the craziest pair of speakers ever! I can't think of another adjective! Congratulations just for thinking about it ...
I applaud your persistent efforts to achieve the best sound possible. Transparent, open, uncoloured, and with realistic body and weight is basically what the goal is; you are not far off with these speakers. Perfection can never be achieved in my view, but that should not stop the true audiophile from aiming to get as close to it as is humanely possible.
Very nice! I started building my own speakers many many years ago. For a time I would listen to high-end speakers in the high-end stores and think, "I need to go rework my DIY design to try to match this". For well over twenty years now however I go into the high-end stores, listen to 5 and 6 figure price tag speakers and think, "why would anyone buy this crap". I started building open baffle in the mid 1990's and haven't looked back and I have zero interest in any high-end commercially available speakers, especially box speakers. You have done a great job on this system, I would love to hear it in person, I bet it sounds fantastic! I'm looking at the Dayton Ultimax myself at the moment and will be ordering one within the next couple weeks for evaluation and distortion measurements. My application for it is actually to use several of them in infinite baffle for 30 Hz down to single digits in my new home theater. There will also be sixteen 15" drivers in open baffle in the room to cover about 80 Hz down to 30 Hz. A lot of people praise the Ultimax but all too many might be too easily impressed, I get the feeling you are more of a purist so when you say it's the best bass you have heard it builds my confidence that I will find them to be acceptable. Btw, I notice you have everything soft mounted...floating. Have you been talking to Brian Elliot, the guy that taught Siegfried Linkwitz about open baffle? Brian is big on soft mounting and he's right to be so and so are you. Thanks for posting this video!
good for you. wish i have the knowledge to build my own speakers. but i tell ya. making your own is WAY MORE REWARDING, & you get a lot of enjoyment out of them than buyin' em from the store.
@@ColocasiaCormBrian Elliot is the guy that taught Siegfried about open baffle. Unfortunately he has no internet presence, not even an email. He's 94 years old so he's pretty old school. I haven't been out to visit him since before Covid, I'm hoping to get out there while he's still with us but right now my job is keeping me everywhere but the Bay area and of course home in TX.
These look amazing i would love to actually see how they are built, and some better detail, maybe a description on how you did everything….. they look really nice thanks for sharing
Very cool setup. I found your stuff just recently when I was looking for open-baffle sub designs. I've been a fan of open baffles for a while, but now I have to try this baffle-less design I think!
I've read too many horror stories about the surrounds coming unglued on the Ultimax line. I had three HO15s in my car and they all had issues; Parts Express replaced them but, damn, the amount of QC issues is scary.
Thank you for all you have done by expressing your creativity through experimentation and implementation. I lament not being able to buy a Salvation/Terminator rig while you were still in business. For the money I can't think of a comparable player that could compete as I still read of positive comments from still enthusiastic owners. Wish you could come up with something new based on everything you have learned so far.
Hi. Thanks for sharing all of your buildings and tests. I spent a great deal of time checking everything that you did. I have finally built similar bass unit's and can confirm it's amazing. I use 18" RCF drivers. Many many thanks for sharing. I have the 18" on behringer as you to 95hz then two sets of 4 x 8" scanspeak isobaric traditional sealed towers from 70hz to 800hz passive on traditional xover then a pair of original Heil AMT tweeters from around 750hz. Not sure if you read these comments but if you get a chance to hear ESS Heil amt's try them i am sure that you will love the sound.
What a great and clever design. Through my headphones it sounds fantastic. You mention Celestion using that type of configuration. I think that Linn used that as well and called it Isobarak, back in the 80's too. Of course in a box though. I did hear a pair and they sounded pretty good for the time. It seems things have advanced beyond them now. I too love open baffle designs because they sound more realistic. As I am a drummer and bass player I listen to those very closely in recordings and open baffle speakers done well, just seems to capture the dynamics so much better. When a drum is hit I can almost tell what type of head is used vs box speakers seem to mush things together and don't let the separate freq.'s transfer to the listener like the OB's do. Well done and perfect music for the industrial looking speakers of the future. Regards.
Isobarik design speakers still in a box. The bass detail occurs with open baffle as box not absorbing, reflecting or loading bass driver. Only issue is volume lower in open air.....but the UM18's using in this configuration give plenty!
@@TransFiAudio I agree your set up as heard through my headphones sounds marvelous. very realistic sounding bass. Also you had me looking for my old copy of Man Machine could not find it and not able to buy it these days , apparently.
Infinite baffle or open baffle give the most clan crisp bass I know of :) If you have a house with for example a loft with big enough volume inside you can make a infinite baffle array and use many 12 to 18" subs arranged in a manifold so they cancel out their rocking motion (if not you need a extremely solid brick wall to be able to stop them from rattling your house). You need more woofers because open air and infinite baffle loose 6db pr octave from 70hz and down and you very quickly end up with very long strokes that will bottom the magnets and get destroyed if you do not have many biiig woofers :)
Hi very excellent video indeed I was really looking for something of the kind First of all my sincere congratulations I have some comments Two actually 1) i really think that a high pass filter should be applied to the arrays If you send to them also the low Hz the IMD will increase for sure 2) have you considered a D'Appolito arrangement for the drivers in the arrays ? i mean with the smaller drivers placed in the middle of the arrays ? disclaimer I love D'Appolito concept immensely Thanks again and kind regards gino
Nice speakers. Thanks for sharing. That music does not tell us much about their ability. I see the bass units running to the limits of their excursion but I just don't know if I hear it. If you play a natural well recorded acoustic piece with full range covered, we might know what these can do.
HELLO ; KIRK HERE. THANK YOU FOR SHARING THIS AMAZING "DIY" SYSTEM. I'M ALWAYS TRYING TO IMPROVE SOUND FIELD AND SND. DYNAMICS. I TRULY THINK YOU SHOULD ( PATENT) THIS DESIGN AND CONSIDER RETAIL MARKET !! THANKS A ZILLION ; KIRK'OUT'PEACE
OH MY! I was just speaking with some of my car audio friends and competition audiophiles about open baffle systems. Even line and Bessel arrays. Mainly about how to possibly incorporate them in to a vehicle. If it could be done or if a type of aperiodic membrane behind the wideband drivers would help. I've already became a huge advocate for widebands in the car finding that a 3 inch driver is more capable of reproducing the highs with the loss of bottom end of course. Smaller drivers can move fast. But I back them up with a 7 inch midbass that play down to 40hz and up to 300hz easily. This lets them catch to the 3's in my dash. The widebands also do better firing up into the 45 degree glass boosting the highs. Of course I run a capable 31 band DSP and all drivers are actively playing. The sub is infinite baffle though. True IB as the back waves of the 15 are routed out of the car in to the atmosphere. This gives me a response down into the low double digits. But now I'm wanting to experiment with a horizontal array using the glass for a horn effect. I hope. It's just very nice to see this video and the well written thought process and documentation. Thank you so much!!!!
What's the purpose for woofer face to face? Wouldn't the back wave of the first woofer just cancel out with the front wave of the 2nd woofer? Doesn't look like the isobaric load either. Does this improve sensitivity?
Hi. The link isn't exist anymore. Awesome speaker and awesome result! Edited: I found the page about the speaker in the homepage, but not directly to the above link. Thanks for your work inspired me

Stunning really,...bravo! Bass is enormous and very controlled and highs are very open and clear. Marvelous. Is this your own design or did someone else design the basic crossovers etc? Cheers.
What’s the theory Behind the placement of the sub speakers ?. Is it sort of open baffle isobarik placement and is it sensitive to the distance between them ? Or can you just grab which spacer you have .
Similar to System 6000 Celestion open air dipole bass I used to have. One problem is those I had did play in push pull making a lot of shaking. Figured out mounting them in a w frame to cancel the rocking movement would solve that. The spacing I think need to be correct in total open air like this, mine was made from factory. I never got around to try making the w frame for them, but I have seen one youtube video of professional car stereo builder do it that way and it worked perfectly :) .
@@UCNP9CfV-_hWihZRL0Hn4PMQ How specifically did you happen to suspend those UM18 woofers? Is there a strap underneath the magnet? Been contemplating a suspension build myself after checking out these videos and some threads on diyaudio. Thanks
Wow I remember seeing some of these open baffles on your webshite in DIY Audio forums. That is quite a journey! Have you considered line array or line source with air motion tweeters / similar technology?
Of course listening to an orchestra at a greater distance than any other type of music would reduce the higher frequencies. Your setup in the bass works well but there is a distinct muddiness and lack of transient snap in the midrange. Also sounds like there is nothing above 12kHz. You need either a robust tweeter set very low in level or better mids that go higher up in the range. Its a decent start but it would not convince me to abandon traditional speakers such as it is.
Amazing you can surmise all this listening to a YT video which has gone through several layers of processing. The video will give a rough approximation of what the system will do, and I can throw this back to you by reasoning whatever you are listening to this video on rolls-off at 12khz, and your system suffers from a bloated midrange. Quote from text above, if you bothered to read: "The idea of this video is hopefully to give you a taste of what these speakers will do. Of course, when you listen at home you are not listening to my set-up, but yours. Headphones may be more accurate, but bear in mind you are still listening to my recording taken through a Tascam DR-05x."
@@TransFiAudio Half of what I stated, is basic acoustic science. I have 29 years experience in that field and 40 years owning reference audio gear.

One of them its polarity is reversed. See his homepage about his history about the building of this none buffle speaker. Really a consistent work. I doubt he retired from his building, he will find the best endlessly...
hi, I am very inspired by your bass, I tried a similar one with 4 AE 18, but experienced mechanical noise and sound from aeration magnet. do you hear anything like this from Dayton at high volume? What is the capacity of the bass system, I already have 2 amps like you, considering buying 4 Dayton.
Sorry for late reply. Your are right about vent noise. I have experienced this with my Dipole 18's. Very annoying. Daytons are totally silent, pleased to report.
What..!! Push-pull....? That can't be right... There's no reaction force cancellation in a push-pull configuration. In push-pull (isobaric) there should be a sealed box in between the speakers to maintain equal pressure. This awesome installation has an unsealed gap between them. The point with the open gap must be to let the pressure escape, like in an open baffle manifold...
The design of this speaker evolved over a decade. I went through many designs. The AE's did not give me the SPL's I wanted. There is further explanation at the foot of the video. Eventually, I switched to inefficient, heavy coned, large Xmax drive units, and I fared much better with them. I worked through the 15" Dayton IB395, RSS390, and finally UM18. The cone orientation also evolved from conventional facing forward baffle arrangement, to one behind the other, Legacy style, to face to face naked. This seemed to integrate best in my room. I didnt know why, but turns out other people had done more scientific experiments found this arrangement increased directivity. Dont forget, Celestion had the SL6000 system in the 80's, although it wasnt that great.
Interesting point, however with both sides of both drivers fully at play, typical HD lowering via physical asymmetries wouldn't result ... most likely.
Mmm :) The nice clean crisp bass you get from infinite baffle and open dipoles + the beautiful room feeling it gives when rest of the speakers is also dipoles :) You might try making a w frame for the dipole bass to make them play push push / pull pull to cancel out the rocking motion and vibration they get when they play push pull (I would think a lot of energy goes to waste like that and never got around to try that with my Celestion system 6000 12" x 4 dipole subs). But I see they subs seems to be mounted so they can freely move back and forward? That will make the rocking and vibration much less of a problem (but still waste energy).

......and I guess you would know....right?
Just curious - why use two 18"s per channel? I assume they are acoustically in phase? Is it just to reduce 2nd order HD?
The design of this speaker evolved over a decade. I went through many designs.
The AE's did not give me the SPL's I wanted. There is further explanation at the foot of the video.
Eventually, I switched to inefficient, heavy coned, large Xmax drive units, and I fared much better with them. I worked through the 15" Dayton IB395, RSS390, and finally UM18.
The cone orientation also evolved from conventional facing forward baffle arrangement, to one behind the other, Legacy style, to face to face naked.
This seemed to integrate best in my room. I didnt know why, but turns out other people had done more scientific experiments found this arrangement increased directivity.
Dont forget, Celestion had the SL6000 system in the 80's, although it wasnt that great.
@@TransFiAudio Waow cool speakers. Don't you get weird diffraction from your two subwoofers almost touching but with a space?
Interesting point, however with both sides of both drivers fully at play, typical HD lowering via physical asymmetries wouldn't result ... most likely.
Hi. My videos 4fe35 dual series port desing
This is out of the box design, very literally
Them Subs Jeez
oh sweet lord
The only flaw I see is that I wouldn't be able to keep my eyes off them when listening to music. 😂👀

"Cheese burger cheese burger cheese..." Awesome lyrics!
Mmm :) The nice clean crisp bass you get from infinite baffle and open dipoles + the beautiful room feeling it gives when rest of the speakers is also dipoles :)
You might try making a w frame for the dipole bass to make them play push push / pull pull to cancel out the rocking motion and vibration they get when they play push pull (I would think a lot of energy goes to waste like that and never got around to try that with my Celestion system 6000 12" x 4 dipole subs).
But I see they subs seems to be mounted so they can freely move back and forward? That will make the rocking and vibration much less of a problem (but still waste energy).
no tweeters?
Im pretty sure those dont need tweeters
How much is this kit?
Looks like about 700 a speaker, amp might be 200, dsp $100-500 depending on level of sound quality you want.
@@arande3 DSP is $6K retail.
@@craigcharlestone 😀 "depending on level of sound quality you want" is a key phrase in that sentence!

Too bad it requires a $6,000 DSP (DEQX) to make this magical.
not true, the only thing with DSP here are the subwoofers, and that DSP is built in to the amps. They cost around $600-900 a piece...
@@craigcharlestone im not the uploader, but everything is explained in the description...
@@FSXgta DEQX DSP preamp is $6K....add extra for the super cap supply. explained in the description
Need the DSP amps for woofer XO, but not the DEQX, which was recent secondhand aquisition....and working flat at the moment.
Garbage thing
