Tear in magnetostat membrane: What to do?

Klimon · 26th February 2006, 07:35 PM

Hello,

I just made a small tear in the membrane (ultra-thin plastic sheet) of a magnetostatic tweeter - Now my question is if this rip will expand due to vibrations (what it's made for

and should be glued (with a fine hand and close to no glue) or can be left as is without causing further damage? I can't hear any difference between the non-damaged tweeter and this one so if the damage stays as is all is fine by me. Replacement membranes aren't available anymore btw (Technics TH-400).

Thanks for any replies!

The front (what you see) is a layer of fiberglass over top of the mylar sheet with the copper circuit on it. Have you sliced through the fiberglass into the mylar?

Yes, the hole goes right through the membrane.
