Space : I can get the 2 P-12's for $317. Will this be too much/over powering for my setup? Or will a single PL-200II be better? I've read everywhere that dual sub is better. My setup : Klipsch R-16F Floor Standing x2 Klipsch R-41M Bookshelf x2 [I'll be selling these, they came in a bundle] Klipsch R-52C Center Receiver : Onkyo TX-NR626
