Anyone ever have this happen to them before? I had two of this brand of speaker mounted in a 4x12 cab. The cab fell over, on its back, the alnico magnet feel completely off one speaker, and appears to be misaligned on the other speaker of the same model. I had 2 old Celestion speakers mounted in the can with these other speakers, that went affected. the manufacturer of the speaker said they have not havd this happen before and said it was going to cost me $80 to recone it, then when I get the bill, it is for $100. I mount the speaker in the cab and something wasn't right. I isolate the two speakers and test them individually and the other one, the one I didn't send in, has as issue also. Anyone ever have this happen? I have many cabs with all kinds of speakers, and have never experienced this, it heard of it before. I've had cabs fall over, fall out of trucks, get run into in the parking lot, but I've never heard of this. This is an expensive alnico/hemp speaker.
