Well, just one relatively small sealed sub in 2800 cuft (assuming sealed room and 8ft ceiling) probably wouldn't do it, duals are a better goal. What's the complete room situation, was I right on ceiling and being sealed from other rooms? Is this mostly for movies? I'd be looking for more potent ported than the BIC (altho have not experienced the BIC think I have a fair idea). I probably wouldn't consider the SB1000 at all, but that's me.
No diy interest, eh?
