I am running a Trace AH350SM (350 watt) head into an Eden 210XLT and 115. The tweeter is producing all kinds of buzz and distortion at all volumes. When I turn the tweeter all the way down, that gets rid of that but then I am noticing some "unnatural" distortion - that farty sound - as well and I am not sure where it is coming from. The overload light on the amp is not lighting, so I don't think it's the amp clipping. It also seems to be happening at all volume levels. After an inspection of the speakers, I do not see any tears or anything. I've set all controls flat and plugged directly into the amp and the basses I've tried it with are passive (no dead batteries). Both cabs are 8 ohms and the head accepts a 4 ohm load, so that should be ok. Any suggestions?
