If your maggies are 8+ years old, the adhesive has probably broken down. I had to send mine back for repair to both panels. Call them. They are very helpful
Blowing Magnepans
Has any one experianced blowing out the base panels. I know the tweeters stretch. it seams like the more power you feed them they just absorb it and become more full. if so what did happen? did the mylar stretch or did the wire just come loose from the mylar? (I realize there are fuses but).
