I have done the two drywall layers with a "a channel" between them. It works very well. However, bass waves are so long, it's pretty hard to keep them from penetrating and leaking into other rooms.

Soundproofing
I have an unfinished basement space, roughly 1000 sqft that I would like to convert to a TV and 2-channel listening room. The ceiling is open floor joists to to the first floor, any recommendations on soundproofing materials that I could use to rough finish between the joists. Floor/ceiling joists are 2x10's.
Thanks,
David
