I am looking into the SVS PB10-ISD with great interest. My current audio setup consists of a Marantz SR5300 A/V receiver and a pair of Mackie HR824 studio monitors. These speakers are fabulous on their own, with a frequency response of 37hz to 22.5khz +/- 1.5db. mackie.com/products/hr824/index.html They have a monsterous low end for there size. Its only when I feed them the lowest power hogging frequencies, turn up the bass knob a little, and turn up the volume dial to way above average listening levels do they start blinking their overload LEDs. I am perfectly happy with my current speakers and rarely push them, besides I live in a townhouse with neighbors right above me. However, I've tasted the SVS flavor as I purchased a PB12-ISD for my friend, it was insane. It's just hard to justify for my situation, given the fact that my Mackies do such an outstanding job on their own.
