Another "Tell me what to do" question. But hey, it's a forum, why not! Peavey allegedly rates their speakers liberally. I've got a 300 watt tube amp I've decided I'm going to keep (I thought there was a problem, and got antsey!)... and I'm using a 215C cab loaded with BE 1504s. I have opportunity to pick up a 412 TXF for cheep, but the BW15s I have are rated 350 "rms" each, for a total of 700 "rms". The TXF is only rated at 600 "rms". I'm answering my own question, right?
