New Magnaplanar 1.7 delaminating and buzzing.

if these are new speakers, call your dealer from whom you bought them, or magnepan customer service

I have, it's been 6 weeks and one was shipped for repair and lost in transit in New York and the other panel unglued from the frame just sitting and waiting for it's mate to be repaired, in a heated house. I bought them brand new in January and the diaphragms just started buzzing and shrinking back. This is unacceptable for  a premium set of loudspeakers costing $3200.00. They sounded  amazing for a month though! 

Really sorry to hear about your experience. It must be really frustrating. Appearenty there was a manufacturing problem… you probably got consecutively produced speakers.

It is a real shame your dealer just didn’t give you a replacement the moment he heard about this. Mine would have given me his demo pair until I received my repaired unit.

Call Magnepan and ask about your repair and what you should do with the other one. I'm not sure how the new design can buzz but see if you can get them to clarify the issue.
