How can they not effect the sound


I frequently see advertisements for speakers that say there are dents in a driver but it doesn't affect the sound. Considering all the work that goes into the cones, how can that really be true?

The effect of the speakers is to make the sound but the dents affect the sound!

Using a vacuum is a very good idea.  If all else fails, try grabbing some Gorilla tape and ease the sticky side into the indention.  Then a gentle (or not so gentle) tug.

This sounds a bit weird but I’ve seen it done easily & successfully for a dented in soft dome Morel tweeter: simply use your mouth  barely touching the tweeter & suck in like your drinking from a straw. Instant fix & sounded identical once again to the other speaker. 

I’m sure there’s a teeny tiny difference if there’s a dent on any driver, but I doubt very seriously that most anyone can hear the difference.
