My son loved the music so much he..... has pushed in the centre dome of one of my speakers. It seems to be a plastic material and now looks like a table tennis ball that a finger has been forced into. Must admit that I can't hear any difference in sound quality (!!) but any ideas how to repair the damage.....?
Follow Ups:
If the sticky stuff or the vacuum ideas fail, then try this:Take small diameter sewing pin, and bend the first 1/16" or so into an L shape (down by the point). Carefully force the point through the dome and then pull gently on the shank to pull the dent out. You may have to do this in several places to restore the shape. Once you have the shape restored, you will have several small holes to repair. Clear nail poilish or polyurethane varnish can be used to seal the holes. Just a tiny dot is enough.
I have used this repair on several finger-poked domes with very good results.
thanks to all. I'm just off to try the bluetac, tape and vacuum cleaner - sounds like a post to another sort of forum......
dented parts.make sure the blutak is well warmed-up by kneading it with your fingers for a minute or so.
the tape idea is also good.
or you might try gently pressing at the points where the dent meets the undented section.
ive done these methods successfully on various dented dustcaps/tweeters.
but have also failed with a few.
If this is on a woofer or midrange driver, it is probably just the dust cap and will not affect the sound at all. You can get a vacuum cleaner and gently allow it to suck out the dented dust cap.

I have had this same problem recurrently with the soft dome tweeters on my Thiel CS2's. The imaging is clearly destroyed when this happens. I called Thiel and they recommended using scotch tape gently applied to the tweeter and pulled to restore the shape of the tweeter. Once this is done, all is well again with no noticable degradation. I don't know how well this would work with metal or plastic domes.
