An experienced audiophile friend uses the voice test on candidate wall treatment materials. This is done by speaking while walking up to a sample of the material, and listening for timbre changes in the reflected voice sound.

We were in a store one day when he showed me this technique. We got some very strange looks from other shoppers!

A medium wool felt gave the most natural sonic reflection.

Gr�f & Lantz,

I would suggest that you observe this worldwide internet audiophile forum post about a possible future product line/design option:

http://www.audioasylum.com/audio/tweaks/messages/16/169588.html

Many audiophiles worldwide have keen aesthetic interests (as well as their possible partners to please) concerning acoustic dampening of both home theater and 2-channel high-end audiophile listening environments.

Feel free to reply with questions.

Sincerely,

Al, if Gr�f & Lantz postures a positive reply, perhaps David Aiken and yourself (and others) might wish to colaborate in discourse with them about such an engineering-meets-art/design topic... Seems like a fun idea to me. RSVP

Regards,

Duster

  Hello: Somewhat off topic.... I've never considered felt , but it sounds promising. To help reduce inter cabinet resonance, I have considered (but not yet used), a thin cork or balsa wood
  layer on the inside of my speaker cabinets - the kind that can be found in hobby & craft stores. Does anyone have any experience w. this? Thanks,Vasil

    I've used balsa wood in platforms to reduce vibration, making a constrained layer construction by using 3 or 5 layers with the grain of each layer at right angles to that of adjacent layers as in plywood. I think balsa works quite well in that sort of use, you can construct a quite light but reasonably rigid platform quite easily. You should paint it with model aircraft dope to make the surface a little more resistant to scuffing.
