Successful Repair

[JDeV]

I recently "undented" the dustcap of a speaker with a vacuum cleaner. It was quit easy, like this:
1st tried to suck out the dent with nozzle only. Did not work. Then cut off the neck of a plastic bottle and put it inside nozzle. Then closed "sucktion control" fully. Dent then slowly start coming out. About 30s later it was almost 100%.

Thanx for advice from walker, BAM and JOE DIRT®

you may be able to get rid of the remaning smaller dents using some sellotape. It's worked well for me in the past...

I've found that, as the plastic relaxes, it goes back to circular on its own...

Vacuums are great! I punched in the cone on my brand spanking new Audax HMs after mounting them in my enclosure. But, as I lifted the speaker (with screwdriver in hand), I noticed the the cone was popped in...F (fill in blanks). Grabbed vacuum that Mom had told me to put away hours later...and voila!

Moral: Don't buy new drivers if you put your vacuum away, you won't get the ingenous idea of using it. 😉

You could do the same to tweeters using a straw and sucking with your mouth🙄
