I have the KSW-12 Powered Sub I just purchased to accommodate my JBL ND-310's and to be honest with you, the dual 10 inch woofers put out more bass than this does. It seems I have to turn the volume up to 2-3 (7-8)sometimes higher to get the "BASS" feeling or the "THUMP". I am using the Monster Subwoofer cable with the "Y" connector and all the other good stuff. I adjusted the Hertz or Line Level input with still no success. Do I need to turn this unit back in for a new one? Or is there something I am missing. The location of this speaker is right next to my Main Speakers with the bass side port facing the wall. Thanks
