The sound of wires delaminating from the Mylar usually can be heard with deep bass notes.If you place your ear close to the panel you should be able to isolate the location. I have in fact felt the area in which the buzzing came from and with a lite touch of the finger was able to stop the sound from continuing.(never touch the ribbon though) This is how I was able to troubleshoot my issue and corrected it. This was on a 14 year old panel and the fix was simple as I mention in a previous post.
I have heard of a flapping sound that people have mentioned in other forums(audioasylum). I have never heard this myself on any of my Magnepan speakers. Your amp may be clipping causing this distortion. How long has this been occuring? Is the amp newly added?
Again post on the audioasylum as I mentioned. There are threads on this subject that you can review.
Good luck
