1" 15 ply birch plywood for speaker box

Just right.

If some if good, more is better and too much is just enough! :mr-t:

overkill = just right

walls will be one inch thick? naw not overkill.

depends on how much bracing you do

matrix style bracing with carbon fiber wrapped over it, then yeah maybe overkill. but **** cool at the same time! :brainiac:
