i own a stf-1 , satisfied with it as i live in aprmt, 12x15 living room. But if your room is gonna be bigger i would really recommed a bigger sub, and since you listen to more music than movies, STF2 will b the way to go. if u can stretch a bit, vtf line is the best u can get.

Bottomline, Stf1 may make u feel wanting more.
