Is there such a thing? I just blew my EA's, then I went to my backup Genz Benz 210's, and they're blown now. I haven't changed anything in my rig. BBE SS pre, ADA Power amp. NOW, I did have issues with the EA's before (I think I just pushed them too hard for too long). So I'll forgive EA for that . BUT, the GB 210s I haven't had a problem ever! One gig 3 years ago, I did push them really hard that the light was going off inside. But that was it. Oh, yeah. The guitar player did tip them over on the sidewalk, and the the front fell face first on the pavement. :scowl: In all fairness, our guitar player is quite clumsy, and I really shouldn't have let him touch any of my gear... one time he actually fell off the stage... if that gives you any idea of the type of character he is... Could this have torn the cones?
