Does anyone know how a pair of klipsch rsw 15 subs would compare to a pair of svs-cs ultras? I read a review at the svs site and a comparison was given between the two, but they compared a pair svs's to only one rsw-15. I own an rsw and it kicks some serious ass, but I'm still looking for some louder, lower bass and am wondering if I should sell the sub I have and buy a pair of svs's or keep the rsw and buy another one. Any help here would be greatly appreciated, especially if you've had experience with these two brands. Dan M. P.S. Also, I would want to use the Crown K1 amp with the svs subs.
