I've got a pair of MTX AAL 1030B which play pretty nice. Problem is the other night I got carried away in trying to upset the SVS 20-39 and apparently upset the MTX midrange instead. The 10 year warranty is close but I can't find the receipt. The damn things still play at a considerable dB level but with a little more volume the midrange starts to "pop". Please help with any replacement part suggestions or even any other speaker replacements.
