In my quest for a subwoofer (again) I stumbled across the Costco and saw that they are selling 10" Klipsch (I think Synergy series) subwoofers for $199. Now, being the thinking man that I am, i pondered if I get one $600 12" SVS box sub or I could get 2 10" Klipsch subs and save $200 for like a tv. Would I still be better off with a SVS or would 2 Klipschs do the job?
