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.

[jamesmorton]

The cost of the DSP is neatly not mentioned. A for effort, C for research. Two rather large panels
would serve just as well. You captured some significant DO NOT DO THIS constraints.
- panel stiffness
-panel resonance due to corners
- exciter placements
- panel "mounting compliance
- complex panel suspension

Other wise good job.

6:03 really scared the crap out of me xD
And a part 2 would be amazing!

Made these flat panel speakers with a 2x2 project panel and hooked it to a home theater system. The receiver when it did it’s auto tune showed almost completely flat EQ adjustment and had to turn them down. They are the best speakers I’ve heard when you pair them with a sub and considering they cost me <$40 to make it’s probably the best speaker period.

The more things you attach to the panel the worst the treble and lower mids will be. Mine is only hanging off a thin string with 2 small cotter pins in the top of the panel. Compared it to panels made similar to yours in the video and they sound really different.

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.

[vrgo]

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.

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.

[andrinschumacher]

These types of videos are so entertaining to watch, keep em comin‘!
Well done DMS

[ShaggyMummy]

You definitely haven’t fully watched Tech Ingredients’ videos on the sound panels, they described the exact issues you came across with different frequencies being more aggressive, and they recommend making multiple unique panels that specialize. To more evenly cover the frequency spectrum.

[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?

[officialpoa]

TRY THIS ON THE NEXT ONE! ... The panels that are for Treble, cut them in half, the long way and switch the material to foam-core or core plaster board. A smaller/Slimmer panel with a harder surface area, should yield a faster response and higher pitching, making the audio massively cleaner on the top side. ALSO, take your entire front wall and add a 2x6 framed wall, filled with mineral wool, so to deplete all of those early reflection from the front wall. This will in affect, give the audible illusion of having your panels 2 feet from the wall because of the sound absorption, which will in turn vastly improve image and resolution.... Lastly, try using an audiophile grade BEHRINGER AMPLIFICATION MANAGEMENT RACK SYSTEM with DSP and delay zoning. I think you might get better results with it.

Bruh when you talked into my right ear I almost went into fight or flight scared the bujeezus outa me LOL

[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.

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!

[VIDEOACD]

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.

[gung-hochang]

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?

[danascoles]

fascinating how warm they are. thank you

[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.

[JimHere]

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.

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.
