(33,546 posts)The "high tech one" sounds pretty good, but why not a round box? It seems to me that a round box of fairly thin material would create the musical whomp they seem to be after. That heavy, rectangular 3/4" plywood body with rigid, full-height legs is likely to dampen the sound, rather than help it. The box resists the vertical impact due to the height of the sidewalls, not their thickness.
I'd be looking at bass drums, cellos and stand-up basses for inspiration on the shape and thickness of the box. The guy doing the talking in the video you posted has a good idea, imho, with the maple strike plate (although I'd make that round, too) and tuning the thing for specific frequencies (I have no idea how to do that).
That rectangular box has sharp corners with complete interruptions in the surface of the wall at each intersection / corner. That would seem to me to be a good way to kill all the long waves (low frequencies) that appear to be what they're wanting. A continuous, circular sidewall of thin material should resonate with those low frequencies and help move them out the bottom, toward the floor.
