I have a dented tweeter dome, do I have to replace it?
We would recommend that if your tweeter done has been dented that you do replace it.
When pressed in, some soft dome tweeters can be pulled back out again using masking tape or the extension hose of a vaccum cleaner, however, even if the dome is pulled back into place, damage has most likely been caused within the tweeter and replacement is always the best option.

Or at least super duper conservative advice.
This happens all the time and the fixes they mention work just fine.

Says the company who would be happy to sell you a replacement. Try it. If you don't hear a difference compared to the other one don't worry about it. If you do, replace it.
Remember that dynamic drivers operate by putting energy into one area of a structure with the expectation that it will propagate in a predictable way. When you introduce dents and creases you may have a functioning speaker, but it won't radiate or measure the same so you just have to decide if you can live with it.
Yes, it's a dome shape for a reason...structural rigidity. A large
dent won't be rigid, it won't keep up the the outer intact section
of the dome. Funny things will happen, out of phasey stuff.. not good.

Show us proof.
Another audiophile myth.

Not so much a hard dome, but a soft dome will do it. Cones break
up all over, certainly a dented soft dome will.
Seriously, the masking tape approach has worked for me and my friends when the occasional "UH-OH!" moment happens. In my experience even before the fix it's hard, if possible at all, to actually hear a difference with a dented soft dome tweeter. I know that seems hard to believe from a technical standpoint, but I've tried really hard as have my friends and we end up shrugging our shoulders. We still do the fix out of OCD "just in case"-ness and visual appeal.
