Hello everyone! Apologies for the extreme delay, I had my repair guy look at everything and somehow some wires touched which blew all four output (drivers?) on my Denon. Switched to a new but crappier receiver and all seems fine. I don't think anything inside the speakers touched but can you think of anything in the speakers that could have caused that? My guess is somehow something in the receiver or my cables touched something somehow, but I wouldn't mind opening up the speakers to checkfor anything that might be loose. Is that easily done? If so, how? Again, apologies but I appreciate the patience!
