    My Genz Benz shuttlemax 6 went nuclear one night while hooked into my UL410 and made an increadibly loud squeal when I tried to adjust the mids. GB hase been fixed, but since then the tweeter adjustment on the 410 is unresponsive. I can hear a hiss in the tweeter when the amp is turned on but no sound comes through it when playing. Also noticed some slight distortion on our last gig that the rest of the band said they could hear too. Is my crossover toast? If so, will Epifani sell me a new one?

    I also fear one or more speakers are blown. B&C has a new 300watt version out, will this work in my cab if I replace all four. Believe the cab to be a version 1.

    How do you test a speaker to see if its good. Sound is coming from all four when in my room at lower levels & sounds fine. Dont see any loose insulation.....

    The coil on one of your speakers is toast. The same thing happened to me. It was hard to isolate which speaker coil was shot. We had to check each speaker individually until we found it.
