Just wondering: the other day I inadvertantly started iTunes music while playing through my EV PMP-12MP and it was sudden and VERY loud. Since then it seems fine but my paranoid ear seems to sense a bit of distortion or breakup at the end of a low string note. I am likely being paranoid but it sounds like the issue mentioned above, sort of at the end of a note or chord a bit of breakup. Do you think I damaged the speaker? Thanks!
