To be honest I have no idea! But I will say they are little thin on the bass, so without a subwoofer there is definitely something missing. Thanks for the comment!
I've been using a couple smaller dayton exciters with foam core poster board for over a year now. Works great, and takes no space. Plan on using more exciters for a home system when I need one.
There’s a paper called “A critical review of bending wave loudspeaker technology and implementation” that calculated the optimal (practical) ratio to be ~0.95:1, while equal side lengths are the worst 😮
You did a great job but the fabric does harm the sound. You are increasing the weight of the vibrating surface, decreasing the stiffness of the surface. This means you will get a worse frequency response and loose volume. Still nice work. I'm not 100% sure about my theory tho
Saw a comment on a different video about how you can coat the foam in a 1:1 wood glue and water mixture to increase the hardness of the surface. I'll try it on my pair and report back
According to what I've read, this setup is actually harming the quality of the sound xP The speakers should be like 3in from the wall and have a lot of freedom to vibrate. The best results seem to be when hanging them from the ceiling and a bit farther apart from the wall, and the wires coming from the exciter shouldn't be so stiff. This can make it harder to make them look good, but will improve the sound.
I built these out of end-grain balsa and another set out of insulation foam. The result was 'OK' but zippo bass. Good fun to trial, but I do not use them
I want to try building these. I've watched numerous videos related to the building of them. There's only one peeve I have and no one addresses it. One exciter on one panel is centered. The other panel has the exciter offset. It seems to me that addresses the combined frequency range of only one channel. The way I think it should be is to have two panels for each channel if a complete frequency range is desired for each channel. I honestly get needing a sub-woofer for the set. However, trying to divide frequency ranges across two channel stereo doesn't seem to be correct.
You're correct. The fix is actually for each channel, so for the finished system there should be 4 speakers total, each side with a centred and off centred speaker. One way to clean this up is use 2 exciters on one panel per side
Yeah I love my transducers/exciters..can make the insignia fire tv connect and play sound.......CANNOT make them work WHILE the soundbar is lol. Soooo not so much "surround"...oh well, they're neat. My search fir making them ACTUALLY surround speakers continues.. Sidenote- I used commercial ceiling tile 5-2/3 rule. And a 2x100 amp..all in like 90$...worth it
Hi bro, I built the same speaker using Dayton audio 25w speaker (stereo) frequently response is 80hz-12khz. The output was not expected, the mid is really poor wit voice is sounding like echo. I suspect I did something wrong of the following the caused this issue. 1.)Painted acrylic painting on the panel, like art work. 2.)Using Dayton Audio DAEX58FP Flat Pack exciter. 3.)Sticked the speaker using silicon past. 4.)using wuzhi audio amp. Cheap one. Please let me know what could have went wrong.
The paint will definitely affect the frequency response. I'm not sure about silicon but I guess it depends how much you used. Was the adhesive on the exciter not working? Did you round the corners on the foam? Did you use the 2/5 rule for placement? The biggest concern I have is how it's mounted. Is your mounting method restricting the vibration of the foam panel at all? Including the speaker wire, is the weight of the speaker wire pulling down or did you create a strain relief? The goal is to, as much as possible, have the material just floating in air. Otherwise it's like pushing your thumb on the cone of a speaker. Maybe the ones you made could be artwork, if you painted them nicely and you could use blank sanded ones and see if they sound noticeably better.

Made it in the way to avoid the he weight on the xps board.
Is your panel material the same and is it extruded polystyrene? Painting does not change anything, I've made a dozen versions of these things some with paint, some with fabric, some with frames, some round, some triangles - hard to make them sound any difference. Overall size is the biggest thing, not paint. We didn't even sand some of them, very hard to tell any difference. Check out AmplifyDIY and the variations he made, we did what he did but you can see him do it - very hard to mess it up. Maybe your exciter is too small or defective, or maybe the amp is too weak.
There simply are no speakers of an Ultrabook that are fine! ** ... ... ** Currently that is. Look if you can turn the surface of an Ultrabook into a speaker (which is close to the subject of the video), it could sound really good :)
i've build these speakers and they need to be in high distance from the wall (on the wall they are worse) and lack both in high end and in low end, pretty horrible sounding
Acoustic transparent fabric is probably more ideal and not very expensive. But honestly unless you're an audiophile you're probably not going to notice much of a difference. And I doubt an audiophile would be caught dead with these speakers. Not that they're not good, audiophiles are just kinda elitist and these speakers aren't made of enchanted spider silk and black magic.
I made portable version so of these so that i can move them to backyard or camping ..here is my build link ua-cam.com/video/c9Wn3s_-QSE/v-deo.htmlsi=YkYHWrT_DtlwbwNk

I'm considering adding some to my living room as well!
Can they work as a surround system and can they use dolby atmosphere or 360audio?

Tech Ingredients said the same thing in their later video.
That's kinda nuts that it's so close to 1 with 1 being the worst

Most people show these flat panel speakers with music. How well does it work for vocals/movie watching?
Very very interesting, I didn't know such a technology existed.

What a good project. Good job again. Thanks for this amazing project

if you get 4 exciters with 2 same layout with 2 per panel, its amazing but twice the cost

I am considering making some of these speakers. I was thinking of spray painting stencil images on the panels.
That’d be sweet! I think that’s turn out awesome as long as you keep the spray can far enough from the foam panels 👌🏽

Hi. Thanks for doing this but the background noise makes it unwatchable for me.
Hi is it xps please ?
Can you tell which of the two delivers better low frequencies - the centered exciter, or the one that's 2/5-3/5?
Para frequências baixas é interessante que o painel seja grande e fino, como um 100x30 cm por exemplo.
Buy a cheap klipsch 2.1 thus solves sub and amp.
Ooooh that’s a good idea!
sir its very good I am planning my full setup home workshop and channel from india
Thanks! I'm glad you liked it!
Would you be open to making more of the custom 3d printed wall mounts and selling them?
Thanks for the comment! I typically don't do that, but I have posted the mounts on Thingiverse: www.thingiverse.com/thing:4971907
@@ModernHobbyist Are they measured in mm, cm, or inches?
@@adamteplinsky6722 Should be mm.
i've build these speakers and they need to be in high distance from the wall (on the wall they are worse) and lack both in high end and in low end, pretty horrible sounding
It's important to soundproof the wall behind the panel if you get nasty resonances.
Seend It.
why are you sanding it if you going to cover it with a fabric? )))
The surface is denser than the foam core, causing more of the sound waves to reflect back into the foam, reducing volume and clarity.
And you know how to wear a baseball cap properly 🙂

Hahaha every negative video I've seen on these speakers was a audiophile that praises the cone gods haha
you shouldn't have placed the exciter in the center of that panel, as this will lead to excessive harmonic resonance

maybe an upgrade for your spekers.
U lost me at fabric. You keep quoting tech ingredients but completely misunderstood 😂
