I bought my first pair of magneplanars the other night they were going great and then i went to play a movie and one of them started making a rattling noise at very low frequency. I'm brand new to these but from my limited research i believe you can repair them yourself-I read something about coil wires at the bottom of the speaker coming loose and was wondering if anyone had successfully fixed a problem like this on a speaker of similar size to the magneplanar 2.7qrs
