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.

Very carefully with a hair dryer set on the lowest setting and moved around quickly.  Don't hold on the same spot for very long.

I've used this method on Maggies, Acoustats, Martin-Logan and Sound Lab speakers with excellent results.
