Surrounds But Not LCR
Can I use SoundPower with my surround sound system?
Yes, you can. One SoundPower system can handle the surround portion of a 5.1 system; two can handle the surround speakers for a 7.1 system (RF, RR, LF, LR.)
Unless you have a very small setup, you should not try to use SoundPower for the main speakers (left, center, rear.)
