My basic system consists of the following: + Denon AVR 3802 + Klipsch RF3II mains + Klipsch RC3II center + Klipsch RS3II surrounds + Klipsch KSW-15 subwoofer I'm VERY disappointed with the output of the subwoofer. My old DCMs with 12 in. woofers kicks this systems butt for bass and overall throughput. Could I have set up the new system improperly? What could be wrong? HELP?!?!?!?!??!?!?!?!?!?
