So something is seriously wrong with my Eminence Kappa Pro 12. When I hit a note it there is a "ringing", might be called a buzz but clearer, that goes away as the note gets quieter. It is *very* annoying. If I swap in a different cab it does not happen, so the amp and cables are good. It also still happens if I run straight to the speaker so it is not the jacks or the crossover. It also happens with the speaker out of the cab. It also happens with a different bass. Fhewww. It does not look creased, but this is to the very untrained eye. This speaker has about 50 hours of playing time on it. Except for a quick initial test, it has always been used in parrallel with a CXL-112. In fact, it was bought to give more of a "vintage" vibe to the CXL. When I used it with the CXL, the CXL dominated, so it would probably mask the problem Any ideas as to what is wrong?
