Good article, thanks! Great material he's using, its stiffness is = to (27) lamination/~1.422" thick BB ply!

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.
Excellent stuff, thanks for posting it!
Looks like density wins, for sure. Also liked the horizontal vs vertical bracing.
And I learned a new word "Adiabatic" It's a gas!

For large panels I was thinking that 3/16" cement sheet could be used for the rigid centre layer to minimise weight. Whole panel coverage may not be essential. Treating the front baffle would probably much reduce driver induced vibration transfer. Weight will always be a limiting factor in large enclosures.
So by polymer composite any idea of what he is referring to using?
e.g. Carbon fiber, some sort of fiberglass/resin, ? (My knowledge is lacking here)
Something we can get at the local home center - and if so, is it workable without 'special' tools?
