NOTE-1 BELOW: This video shows how this mounting system works for panels with 2/5- 3/5 mounted exciters & panels with centered exciters. For best results, single speaker channels should have exciters mounted at the 2/5 - 3/5 location for each speaker (4:09). Dual speaker channels should have one speaker with a 2/5 - 3/5 mounted exciter and the second speaker on that same channel with a centered Exciter (4:07). Thanks to Tech Ingredients for The World's Best Speakers.

NOTE-2 BELOW: Like any sound emitter, these transmit quite different at surface contact than with more distance from surface. I noticed significant variations from 1 to 2.5 inches from wall surface to back of DML panel. Changes certainly continue at greater distance, but then we're no longer talking about wall mounting. I designed this wall mount system to save floor space & because I wasn't interested in displaying the mounts or the exciters (backs of DML panels). But you do need some distance from a surface.

Small changes make big differences near the surface. Against the wall had the highest coloration. A foot from the wall, not so much. My experience was that at closest (back of exciter 1/8" from touching wall surface) your ears can locate the exciter position on the panel from the front surface without seeing it. Individual preferences will vary, but I was happy with the back of the exciter about one inch from the wall surface. That puts the back surface of the panel 1.5 to 2-inches from the wall surface.
