I'm told that I need a subwoofer to round out the bass and pressurize the room. I have Defitive Tech 2002 w/ 12" power subs, C/L/R 2002, and BPX rears. Denon 3808 drives the system with a PS3 for movies/games. It's been recommend to get Rel T2 for (music) or SVS SB12-Plus or HSU VTF-3 MK3 for (Home Theater). I'm not a tech person and need some input!!
