Never done it myself but there's lots of good info on other forums (audio asylum and audiocircle) and Google.

Magnepan Mylar Repair
One of my MMGs has started doing the bass slap and I think the issue is the mylar has stretched. I took off the sock and visually nothing looks wrong. Does anybody know how to re-tighten the mylar? I contacted Magnepan and they are only doing warranty repairs for the foreseeable future.
