Hey fellas,
How many of you have built a DML panel speaker? Is there any DML panel love out there???
After reading about the Podium Sound panels and making my way through the expansive AudioCircle thread "NXT.......rubbish??....THINK AGAIN!" (http://www.audiocircle.com/index.php?topic=70541.0) many months ago, I have finally put together some quick test panels to see whether or not these might be an option for the living room were I could set up and tear down the system and carry the light panels away with ease.
The first panels I put together were small and simple. 1" thick Owens-Corning 2 ft. x 2 ft. Project Panels from Home Depot (http://www.homedepot.com/p/Project-P...-PP1/203553730). The panels are sanded on both sides with a palm sander with 100 grit. Both sides are then treated with a 1:1 mix of PVS white or wood glue and water; this dampens the panel and aids propagation of the sound waves across the panels surface. The exciters are from PE of course, the Dayton Audio DAEX25FHE-4 (http://www.parts-express.com/dayton-...4-ohm--295-224).
How do they sound? Different. Pleasant. Excellent transients. Percussion and plucked strings are probably the best I've heard. The harmonica sections on Cowboy Junkies "Trinity Sessions" has beautiful dynamic shading that makes for a very realistic presentation. Fast and biting without harshness. Didn't measure the response but think they sound reasonable played full-range. Response likely down to the 100Hz range with a laid back HF response that is quite good and not lacking for my tastes. A 2' x 6' panel is said to get down easily to 50-60Hz. Compared to my Tang Band W4-1879 in OB, they are noticeably more sensitivity; 91+dB range.
As I said... different sounding. You have to get adjusted to the presentation as the panels are distant sounding after switching from my open baffles. There is a lack of presence and a sensation that the music is emanating from behind the speaker, through the panel, then to the listening space. Once adjusted they are VERY ENJOYABLE and NATURAL sounding. I listened to Muddy Waters "Folk Singer" (on gold disk) and Cowboy Junkies "Trinity Sessions" into the wee hours of the night a few nights ago just enjoying the dynamics and naturalness. Very nice indeed. All from $30 worth of parts and 1 hours time. Amazing honestly. Would be interesting to combine with an open baffle bass panel. Lots of different configurations.
[edited Jan 4 - The panels have opened after the exciters have fully broken in and the panel treatment has cured (harder panel skin). The small panels are fast, detailed and considerably more clear than the time of the initial post.]
Curious to hear what others have built and their listening impressions. Anyone enjoying DML panels in their system at the moment?
