what is best sub enclosure material ?
Would 1/2" birch plywould make a good vented sub enclosure, or should i stick to the normal 3/4" mdf.
the half inch birch ply seems to be more rigid than the mdf, so i would think it would make a better box.
i would like to know because the box is going into a small space and i need to make up for the lack of space in any way that i can
thanks

I use 5/8" MDF for 90% of the boxes I build. It's only 1/8" thinner than the usual 3/4", but a full sheet weighs about 20% less. Until spans get to 18^2 inches unsupported, it works just as well. Whenever I get to bigger panel areas (which is seldom), I just internally brace.
Birch plywood is an excellent material, but not the birch veneer stuff they sell at Home Depot, etc. That stuff is 7 plies at most, and tends to splinter when you screw/nail it. If you're using Baltic Birch (which can be 20 or more hardwood plies in a 19mm panel) then go for it. It's an awesome material, and can weigh 50% less than common MDF (not including ULMDF or all softwood MDF).
Rigidity is only part of it-- birch will resonate much more than MDF, which is about as acoustically dead as you can get without going to concrete. MDF also has the big leg up in cost factor-- a sheet of 5/8" is $23, and that's at Cali prices. A 5' x 5' of Baltic Birch can go $60.

def flexes a lot more than mdf. mdf is awesome and you can't go wrong with it. you don't get the boom from different materials but honestly i like tight clean bass.
also if fiberglass is done right it can sound really good but is much more expensive and a pain in the ___ to use
