3/4" MDF, two layers, interlocked corners, if you are using a panel saw
you can get airtight without caulk, and it will be heavy enough to sit
still, and dense enough that LF sound doesn't just ignore it like it
tends to do with plywood.  Obviously mids and highs don't need the nasty
double layers, especially if you do mids and highs with a compression
horn, (in which case they don't even need a box).

My cousin does concert type audio for a living, and last time he was on
this end of the country he brought this really sweet 10" driver with
him, it almost looked funny, because the voice coil was 4-1/2" in dia.
The magnet assembly on it would just fit in the hole it mounted in.  I'd
love to build a set of speakers for the house with drivers like that,
you can make them sound good just with a good equalizer and a lot of
power, don't need to spend as much time trying to get the maximum
efficiency out of the cabinet.  

Just throw a couple hundred watts at it, and equalize out the bad
sounding parts.  Of course that is sacrelige(there is something wrong
with that spelling, not sure what it is) to an audiophile, but it is an
amazingly effective approach.  Of course, that is the approach Bose has
always used, hence the special equalizer box required to make the 901s
sound good.
