Hi John, Kapton can take temp tripling that easy, it's very stable, also the ali traces are a constant cooling mechanism, I doult you could get .002 elongation from it in either direction, just my theorys from working with it. Al
PS: Remember it's tuned, can't have that changing all the time.

What are you talking about? Maggies have one-sided magnets ... except for the bass panels on the MG-20 and the bass & mid panels on the 20.1 & 20.7.

Delta - here is what I have learned from watching the panels buzz...there are slight "bows" (bubbles?) in the diaphragm that you can see vibrate with more amplitude than a nice taught diaphragm that does not buzz.

Sagging or wrinkling diaphragms will surely have the buzz, and padding the edges with foam only helps a little. Tension-ing up the panel does little getting rid of a local "bubble", and trips up the tuning. Answer is getting those bubbles out...

Because of this flabbiness, I screwed metall bars in the back of my duettas.
3 bars screwed low, middle and high on the backsides onto the mdf board.
