I can get 2 for 800$ not sure if they are SSI's or SSX yet im waiting on that response.. i was only told SS.. is it worth 800$ for 2 15's even if they are the SSI model? Are they underrated\and if so how much power to they really handle while still sounding nice? Good SQ from these? also... if you have seen the other thread of the few subs i was looking at... are these better\as good as those.. SI Mag.. Crystal Comp X, and some others i forget..
