I currently have the Klipsch KSW-12 and I am not very happy with it. I was looking at subs from SVS like the 20-30pci(the cheapest compared to the PC-plus,cs, and ss series) that sells for $600.00 and I was wondering if going for this sub would make a big difference. The Klipsch has 105 watts into 4 ohms and a peak output of 441 watts. The SVS has 320 watts. I also wonder if the 320 watts on the SVS is peak or continuos watts?
