Proper material for replacing dust covers on ESL-63's?

[240z4u]

Well I am a new owner of a pair of Quad ESL-63's

I was aware that a dust cover was missing when I bought the speakers. I'd like to replace it. The frame and all that jazz is there I am just a bit stymied when it comes to choosing a film. I've read that 3m window film is actually too thick.

What's the correct film to use? I found some PET on mcmaster carr of the correct? thickness at .0005" but am unsure if I can heat this stuff to shrink it the last bit required for a tight fit. The other dust cover seems kind of floppy to me too so it may need to be replaced as well.

Thanks for the help guys.

BTW, here's the McMaster link McMaster-Carr

I believe the dustcover film is 2 um Mylar

Thanks Rod.

2 um is impossible to handle. It must be 6 um IMHO. There is another thread in this topic, see:

Thanks for the link. I don't know how I missed that.

3 Um
for sure. its lightly stretched , 3 Um is easy to do just strecth it without wrinkles on glas and glue or use double sides tape, if you need you can use a heat gun to get rid of the last wrinkles.

its resoance must be way below the panels res, wich is easy its getting it high that is hard so no problems there !

This thread is a bit confusing... are you looking for material to replace the diaphragm or the dust cover?

 

[240z4u]

Dust cover.

OK....I'm still confused. And I'm not familiar with ESL 63 construction. Are we talking about the permanent grill covering or a removable dust cover that's only used to cover the speakers when not playing?

(Dayton Wright gas filled ESL's encased the panel in a gas-tight bag but you wouldn't want to do that otherwise, I figure)

There is an inner thin mylar dust cover that covers all the electrostatic panels. Unfortunately being as it's thin and clear it's hard to find a good photo online of what I am talking about.

Here's a super loose/wrinkly dust cover ; http://www.geocities.ws/quad_esl63/images/service/esl63_dustcover.jpg
