Another pic:
I really don't know what the heck I'm doing with it though. Just lining the walls with that foam stuff from Parts Express and plan on leaving it sealed. I don't have a clue on how to "tune it", so guess I'll just have to leave it sealed.
Cabinet is a Parts Express 3.0 cubic foot behemoth. It is very heavy.
Anyway, I'll send a couple more pics along with the progress I make with it.
