[@v000000000000v]

tech ingredients' original video has like 3 parts and goes way more in depth into the material usage, room treatment, ways to hang the panels etc

[@CoRDSau]

you really need to minimize anything attached to those panels, having four mounts on each one will ruin their sound, i recommend using the smallest possible attachment method you can, i used some nails and twine and only had them mounted to two points, also i would recommend using much thicker sheets. the wall of sound i go out of just two rather large thick sheets of XPS was stunning.

[@abdulhfhd]

I swear audiophiles will never be satisfied with anything.

[@CoRDSau]

@@abdulhfhd This is true. But with these stype of “speakers” you have to think of the panel as the driver cone so you want to minimise anything that touches it as the whole thing vibrates so any additional mass or anchor points actually stop it from being able to move air

@@abdulhfhd your not wrong, but i think thats kinda the point. Forever exploring, looking for more, and how to better the things that you already have. Its the other end of the musical spectrum.

Dayton themselves have an excellent guide to building and mounting DML speakers, and some of the suggested mounts make a lot of contact with the panel. Tech Ingredients put them on the map for me, but Dayton know more about how to do it right.

[@vrgo3812]

Hi please try this: 2pcs of 40x60x1cm 70 grade EPS(not XPS) board in 2.1 channel. Sand the surface then brush coat with 50/50 PVA/water. XO with a sub at 250hz. Cut off the exciter's frog legs just use the voice coil ring to attach. Free hanging the panel instead of mount. Or welcome to diyAudio there is a thread over 300 pages about DML.

This is highly specific, technical, absurd, and amazing. I’m only a novice when it comes to audio, but this is the kind of stuff I like about your channel, DMS. Prior to this, I never would have even thought this could be done. I can’t wait to see what other shenanigans you get up to.

[@xxjjgdrgn]

I tried this in late 2019! Fun little experiment that took forever to get right. After a lot of tinkering I had my tiny concert hall. I took it apart and went back to my triangle speakers 😂. It was 100% worth the 80$ and time invested.

[@fiddlix]

Hell yea do a part 2 for this show.

[@fairisfair]

Hey, DMS, have you ever thought about how to create great sound in a camper van? Your designs of unconventional, budget sound system make me think this might be an intriguing problem for you. I'd love to hear your thoughts and put them to good use! Thank you for providing such excellent content!

[@DeltaNovum]

Attach the exciter right to the walls? And let the camper itself be the resonance chamber :D.

[@VIDEOAC3D]

If they were different sizes you could use the different resonate frequencies of each S/M/L panel to favor bass, mids, and highs before crossing over and DSP'ing.

[@3rdHalf1]

There is no need for different size of pannels. The way DML speakers work is that there is no advantage of smallers panels. A bigger panel can acchieve lower frequencies, without compromise in high frequencies.

[@VIDEOAC3D]

@@3rdHalf1 Thanks, that's interesting. I guess I assumed that the added mass would impede the action in the highs, but add surface area aiding the lows. I'd like to get around to experimenting with them someday... but I have too many concurrent eccentric projects in motion. Lol 😆 And I think my next audio project will most likely be planar oriented or even maybe a hybrid planar-linear driver.

[@3rdHalf1]

@@VIDEOAC3D Fundamentally DML’s work diferently than cone speakers. Cone speakers move air with the cone moving back and forwards. To get lower frequencies - you need bigger speaker cone. But bigger speaker cone has more mass, that is harder to move in higher frequencies. DML speakers vibrate the surface of speaker in all frequencies at once, that total average the frequency you hear(This is why DML speakers don’t have feedback with live microphones). To achieve lower frequencies, DLM speakers need bigger cross-section of surface(example: 1 square meter panel of 50x200cm. will be able to reproduce lower frequencies than 100x100cm panel). With the right materials(best materials are honeycomb cardboard, and carbon fibre panels) , there is no difference in high frequency reproduction between big and small panels. The bottle-neck is that to achieve lower frequencies the size of panels have to increase exponentially. And for sub-frequencies this becomes impractical, hence you need a woofer with DML speakers. Another quick note: To get mo-powa out of DML speakers you don’t need more powerful exciters - you just need more of them mounted on same surface.

[@gung-hochang9573]

I've actually listened to such a DIY wall speaker and I love the wide sound they make. They need tuning, but they reproduce the frequencies in an unsaturated way while it feels like normal speakers become overwhelmed and is so narrow in comparison. Regular speakers simply cannot make this sound, at least none of the ones I've heard even come close to coming close. Like I said, they need tuning and might benefit from complementary speakers, as well as a different material for mid-range, but it's pretty cool stuff and I feel like there's a lot of potential here if it's done right from start to end. The experience is just so satisfying. It also lends itself well to certain instruments that it reproduce quite convincingly. They have this ring to them that certain instruments have as well. I want to see what the actual potential is. The ones I heard had issues, no DSP and no mid-range companion wall speaker means it's far from perfect, but still pretty exciting to listen to. I just can't stop wondering how they'd sound if they were tuned and not mashed together for a quick fun project without DSP etc. Part 2?

[@ABDLLHSDDQI]

Sounds awesome, would love to compare this to a full Magnepan LRS setup in terms of cost and sound quality. If it costs half and sounds good, then awesome. If it just gives that type of sound and is better than anything else at the same price, then still amazing. This is the type of audiophile maker project that very few creators can do, you being one of them. Would love more content on this, I wouldn't even mind paying for the detailed plans if its a reasonable cost.

[@DMS3TV]

This build is about $200 if you don’t count the amps or DSP

[@ABDLLHSDDQI]

@@DMS3TV As I see it, the DSP device is pretty much critical, and amps we would need with a speaker anyway, though that amp would likely still be cheaper than a Schiit Vidar + a preamp that is the minimum good amp required for the Magnepans. So in the end, I guess this project would cost $500-900 cheaper than a Magnepan LRS setup after factoring in speakers + necessary amps for both options, and the DSP for this DIY option, with the tradeoff being it probably won't sound as good as the LRS, though maybe with more tuning of materials etc., it could MAYBE sound as good, and its not as easily to setup or move to another house. I'm still super interested in this project, and I'm still considering with this idea.

[@mhmnn]

Are the reflections from the wall behind the panels not interfering with the sound since the panels vibrate both ways? What would change if you put acoustic panels behind?

[@rhalfik]

So here's the thing. These things are not uniformly dipoles. The membranes jiggle like jelly so they have some monopole component to them. Either way there is a reflection and it does interfere, but their forward projection has already so much linear distortion, that it doesn't make them worse, just different kind of bad. However it's just linear so it can be fixed with EQ. Of course not all of it, but you can get it roughly to shape. This way you get a decent and practical speaker for not a lot of money. Just not decent in a HI-Fi kind of way. They have moderate to high nonlinear distortion. In a conventional hifi driver the nonlinearities mostly come from the motor and suspension, because the diaphragm is so well designed. Here you get distortion from the motor and from the panel. Luckily the pleasure from audio is not just hifi, but also from learning different kinds of sound and this method has it's own signature.

[@richpryor9650]

@@rhalfik Okay, interesting, what kinds of speaks are considered dipoles then?

[@haaspaas2]

If theres anything I know about Hi-Fi equipment it is that gold plating equals premium. Gold plate the foam boards, gold plate the rubber bands, gold plate the mount and dont forget to gold plate the drywall.

[@NeilBlanchard]

I would suggest that the two panels closest to the middle be the only ones to have the treble - they can carry just the treble but could also do the mids up through the treble. Then the panels above and below those two can do just the midrange - this acts like an MTM. And then I would do the outside columns for the bass. So, either a 3-way system, or a 2.5-way system. Either way, you'll need 3 stereo amps, obviously. The two treble panels can be 8 ohm, the two midrange can be 4 ohm, and the 3 bass panels can be 2.66 ohm - IF they are actually 8 ohms. This would make them louder, and the amp could be chosen to work with this.

[@andrinschumacher9503]

[@JimHere93]

This is cool as hell. The wall lives! I like the idea of messing with this. I wonder if pitching any angles to the outer speakers to tow them in would add a desired effect. Also, on a nerd level, would love to see the cable management/amp setup in more detail. This is cool. Would love to see more.

[@fredericnadon6428]

I've had the same idea years ago but I suck at building stuff. Good job! Now what I want you to do is to use this setup to RECORD something, maybe yourself playing a musical instrument, but using these panels AS MICROPHONES. Then play it back. Does the playback sound more three dimensional and accurate? (I'm talking here about having the musician be in the exact same place, with the exact same room acoustics on the playback as the microphone placement. The point is to have your speakers reproduce the placement of the mics, to give a, hopefully, better effect of realism.) Can you try that? Pretty please?

I have some Exciters. For pure fun. They are great. The sound they produce is about as good as it gets for creating a wall of sound, that somehow sounds extremely directional and omnidirectional at the same time. Its the same sorta intimacy you get from headphones, but from in front.

[@RenghisKhan]

After seeing many videos on this topic the main question to me is, what is gonna be their purpose? As a stand alone system (with a subwoofer) it probably needs a lot of tinkering and wall surface. As a supporting system with some decent speakers hooked up to a TV it may just turn your living room into a more cinematic experience without the need for an immense wall. Just trying to get the utmost out of this system might result in a setup that may be reasonably cheap but highly impractical for most homes. That being said, I'd still be very interested in the latter. The former use however would be something I can imagine many people would be interested in for more practical use. Soooo........YES, PLEAAASE do at least one other video on this. My brain is still flooded with questions about this system. I do still think attaching the system to the wall via the exciters should be beneficial to the output of the panels. And I wonder how a guitar shaped panel with dual exciters would perform.... Anyhow, I really enjoyed your video. Don't stop having fun!

[@torbsaudio]

this would be really cool to see as an atmos setup if you can use each panel as 1 source

[@the_nondrive_side]

Smaller treble focusing units in middle sections of a harder material would probably help.

[@thomaswachter7782]

Very interesting. What I really would love to see is the end result of the RB42 array. Even if fewer speakers. I would imagine some comb filtering issues would arise... maybe. I could see the RB42s lined up like a concert array horizontally.

[@willyouwright]

I think the placement of supports on the foam board would introduce modes . I'd say it was best to hang from string on roof. I'd also say driver placement needs to be randomise across panels? You'd have to do allot of individual matching though..

I would really like to see what you can do with the xps pink foam board. Starting with a single large piece per side and multiple exciters. THEN cutting down the large piece into smaller sections with 1 or 2 exciters per panel. Comparison of DSP settings and output along the way would be very interesting. I also have a theory that an oval would be the most ideal shape, so maybe thats the last test. Thanks for your exploration!
