BP 9060 Sub Amp Failure
I've searched this thread and found some posts regarding built-in sub and/or sub amp failure, but no one seems to have had the unusual experience I've had.
I have a pair of BP9060s that I purchased only 2 months ago (on sale at Crutchfield), and over the last few days, the built-in subs and/or the internal sub amps on both towers have failed. I get sound only from the mids and tweeters; nothing at all from the low end. ( I haven't subjected these to any high volume abuse.)
However the "D" logo on the front base of both speakers is on; the power light on the back of the speakers is also on, and blue; the bass control knob has no effect in any position.
Because of this, I went through every possible scenario of what else could be wrong: AC power connections, other cable problems (I use the full range speaker connection only, not the LFE input), incorrect settings in my AVR (Marantz SR7012), etc., and everything checked out.
I finally narrowed it down to the 9060 subs or amps themselves by connecting my center channel speaker (a CS9080) to first the front left speaker and power cables, and then the front right. In both cases, the center channel worked fine, putting out plenty of bass.
I talked with Crutchfield tech support, and they were puzzled, but after suggesting a few other things I might try, they said to call back tomorrow, and they would set up a return/exchange.
I wonder if anyone else has experienced this with these speakers, or other similar models? Previously I owned a pair of BP2000s, purchased in 1995. They performed perfectly for 24 years. Hopefully the quality control on these has not gone down.
I am very pleased with Crutchfield's return policy, though, and I'm glad I purchased these new towers from them.
