I got a refurbished onkyo 5400 a while back and have upgraded the center and two fronts to bic america speakers. (Dv62 si and dv62 clr). Was looking at subwoofers next and curious what the recommendations are. I don't listen to a lot of music on the rig so i guess my use is like 95% HT and 5% music. The room is 20x14 with vaulted ceilings. Maybe 20x14x15. My max budget is probably around 500. Considering bic's subs pl200 or f12, seen klipsch recommended, stf-2, or pa 150. Any other choices or opinions about these subs for my usage?
