I just picked up a Klipsch KG SW passive sub(2 eight inch drivers). I would like to use a Carver m400a to power it and a NAD 7150 for the receiver. The NAD is rated at only 50w but seems much more powerful. My problem is that I know nothing about this subwoofer. Does anyone know anything about it or how it sounds? Would these components work good together. Any feedback or advice would be much appreciated.
