I've only had the cab for a week and it's started buzzing on me today I'm not entirely sure why. I checked the speakers and I don't see any creases (i'm not 100% positive of what to look for, but I didn't see anything out of the ordinary) I also took off the grill and tighted the screws holding the speakers in place and that didn't solve the problem either. I running it with an Ampeg B2R. I can't imagine I'm pushing it too hard, I never had the Gain or Master above half, and I'd think a 700 watt cab could handle 175 watts (or so) of power. I hadn't changed any settings on the amp or my bass in quite a while. I never had a problem with the Avatar cab I had, and up until today the Eden worked perfectly. Now I get a buzz, mainly on the lower frequencies. Playing low D's and B's and such causes the most buzzing. It hardly buzzes on the A and happens less and less on the D and G. It doesn't seem to have too much effect, because playing along to MP3's I couldn't really hear the buzz a whole lot, but playing solo it was obvious. Anybody have a clue what the problem could be?
