After owning the PB-2000 now for over a month I can confidently say that I never had owned a proper subwoofer in the past. Getting the SVS dialed-in and through the break-in period took some time but I am now continually blown away by the tightness and overall focused rumble of this subwoofer. Incredible! There have even been times while watching a 5.1/7.1 blu-ray when there is literally no low frequency "sound" (that I can hear with the limitations of my human ears) but the subwoofer produces an amazingly "invisible" vibration that I can feel in my gut. Spectacular! I am now an SVS convert and wished I would have gotten one sooner. Who knew?!
