Yesterday I purchased a barely used Synergy Sub-10. I went home and hooked it up, and the woofer appears to be blown. It powers on, has a quiet buzz with no signal, and when given a signal it's reproduced with EXTREME distortion. Volume increases with gain, which leads me to believe the amp is good. I called the sellers (seemingly very honest couple) and these are the facts they gave me:
-Purchased 2 years ago.
-Used for a couple of weeks and worked fine.
-They decided they didnt want a theater.
-It was disconnected and stored in a warm, dry climate up until now.
Its a tough situation because I can tell they're being honest.
So....If what they say is true, how could it end up blown? Any idea's?
