Thanks...I sat glued for 40 minutes awaiting a response fron the dB boss.
I just bought 4 pretty cheap 12" 'DJ' speakers for providing sound in satellite rooms. Tough thing to be prepared for almost any scenario without going in the hole for 10 years.
Don't like used speakers. They can be ruined so quickly.
I had two 12" Rockford subs w/500w two channel amp before and they didn't sound as good for bass as when I downgraded to 125w single channel with one 12" sub. I've heard others say the only advantage of two subs is loudness, at the sacrifice of sound depth/tightness.
