These are my first attempted to make DML speakers that sound AND look good. I should probably experiment on cheaper materials first but once I have the idea I tend to be a bit impulsive...
My panels are made from 2.5mm thick carbonised bamboo plywood, and I've coated them with danish oil to bring out the natural grain a bit. They're hanging on customized bamboo clothes racks I found on Ebay - I didn't want to hang them on a wall as they really need room to breathe (like most speakers they sound better when you move them away from the wall) for best results.
The panels are powered by a single 40w Dayton Audio exciter per channel, with no fancy electronics needed. They run full range, although due to the limitations of panel size and other factors, really need to be accompanied by a subwoofer - in my case a Canton 10.3 powered unit that rounds out the sound nicely.
I've started to experiment with bracing the panels for less flex (stiffness is desirable) and my next steps will probably be to progress this aspect of the build further.
Overall, while they're not perfect, I'm pretty happy with my first DIY audio project and in fact I already have my next DML speaker project underway!

I haven't read through all the comments, however, hearing the bad acoustic echo in the room makes me question all of it.
What I find funny is that the 2/5th 3/5th rule almost perfectly matches the golden ratio. Don’t know if that means anything I just find it to be a funny coincidence.
There's a reason he used the foam board and not bamboo. Sound.. you have no base because your bamboo is too Ridgid and dense. They look amazing, but they sound.. blah. The foam on its own may look blah but sounds amazing. It's finding a happy medium between looks and functionality.
Turn it up crank up the music.
Plywood as a resonant material is not the best idea. Example the cheapest guitars are plywood.
The bamboo messed it up man...
Before you buy any PARTICLE board,tap your finger nail side and hear the vibrations, it should have low,mid,hi put your ears close to check again, exiters work differently in low and high volume,use Separate amplifier to control other speakers and woofers 😎🤜🤛📚📕📒📖
I think it's probably a function of your room. Because you have a ton of echo and reverb, the speakers don't sound good to me. Impossible to tell with the way the room itself sounds.
Can't really get a good idea of the resl sound from these for obvious reasons. People of a certain age,like me, might think they look a bit like Corby trouser presses though 😊
That's not the 2 fifths 3 fifths. You need 2 fifths from the side 3 fifths from the top
Real nice setup you made, thanks for taking a time to make this video !
Very nice use of TechIngredients work. I have watched all of their CZcamss on these sort of speaker, and it’s nice to see a more presentable version. Thank you for taking the time to produce this CZcams.
Stumbled onto this video researching DML Speakers for myself.
Sounds nice. I would not shy away from this design. Thanks for sharing.
Thank you bro, now I can further improve my DIY Speakers project.
Even without sub, panels sound great!
They look great ! 👍🏼
Clothes racks are an excellent idea for stands
Resonant points come from sustained reflections on physical spacings at specific frequencies. Reflections are caused by sudden changes in density (impedance changes of material and air) at the edges. Parallel edges guarantee resonant points. There are very good reasons why violin outlines have progressive curvatures with both convex and concave. They have evolved such that no one note is more resonant than another. They even have curved "S" slits on the interior to break up transit distances.
I dig that whole eastern vibe you got going on that setup.
