Ken,

Personally, I've never studied the properties of various types of 
closed cell foam on woven-head triggering, beyond basic density and 
stability, but I ran across this site 
http://www.efoamstore.com/default.asp 
a while ago and was intrigued. The foam store should be able to 
provide a nice foam sandwich for piezos under mesh heads. It might be 
worthwhile to call the place directly to discuss the best choices for 
the application (it might give them ideas about a new market). I 
assume that you've seen Beatnik's site and followed his two designs. 
For the cross-rail type, you can use air-conditoner insulation as he 
suggests, but I find that the tall cylinder with the flat circular 
ends--not the pointed cone or the trapezoid, which slopes obtusely 
from the top plateau--holds up better. The mesh-head drum companies 
tend to keep their suppliers a secret.
