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!
