Magnepan 3.5R buzzing

i have the same problem with a pair of apogees duettas hopfully some one has help for us

Yo Audiableguy, I had a pair of MGIIIa's that buzzed. I sold them. To fix your speakers, you will need to ship them back to Magnapan for new socks. It will bring them back to "new" condition. The problem is that when played at high volume levels (expecially with power amps that cannont handle the transients and clip) the DC will overheat grid (wires)on the sock and deform an area of it. This area will be "loose" compared to the rest of the panel and it will show up as a buzzing noise during certain bass passages. As for the Apogees, the ribbons can usually be re-tensioned if not damaged. More info is available at http://audioworld.com/cgibin/sw/Ultimate.cgi which is the Apogee users web site.

The sock is just the fabric covering the panel. You must be discribing the panel when you are mentioning the sock. What you discribed may or may not be the problem. These are relatively new speakers. Send them back to Magnapan for repair.

The wires on the back of the panels can come loose, that´s probably what has happened. Are you listening at very high volume levels? Good Luck!
