You would not believe how many folks we had actually done custom work with that had us create concrete or gunite enclosures. They were incredible though.
I personally don't agree with you on the idea of fiberglass being a no no... it all depends on the thickness... yeah, MDF is nice and dense and makes for a good enclosure, but when you compare it to a properly built FG enclosure, its not really the same. If you are running a single 12" in FG, the enclosure needs to be around 1/2" thick... most people lay-up enough to make it rigid, but not really so dense. Thickness for Thickness, a FG enclosure made of 3/4 oz matte and polyester lay-up resin is every bit as dense as a MDF box... now, as for concrete or gunite... thats gotta be a little overkill for most jobs... actually, I can't think of a reason to ever go to that extent... could be wrong, but I haven't seen the need for it... crazy idea though.

Anyway...
