I had to take the speaker fronts off to disconnect the woofer, there was nowhere near as much buzz with the woofer disconnected, (still some though) I put the appropriate coil on the woofer while I had them apart. This seems to have helped significantly. It is a el cheapo woofer I might add !!. I wish the guy who built them 4 years ago had known more back then ;-)) But they are still running, just getting used for something they were never intended to do. They were designed for just vocal and flute (100w 12") now they are trying to put percussion, electonics etc through them, I guess they have to expect problems. !!
Thanks Wayne for pointing the right direction.
