Why does a dent to a tweeter not affect sound quality?

@tubebuffer , yeah, as sejodiren posted, that's got to be one of the wildest on topic posts I've read.

OMG... a dent in the tweeter doesn't have an affect on sound quality???
Good One...
Oh, you weren't joking?
Eh, sorry... gotta go now....

@ OP, it does affect the sound, never buy speakers with damaged tweeters. 

You can easily have a tweeter dust cap or “nipple” replaced, for aesthetic reasons. The Speaker Exchange in Tampa Fl does excellent work and this type of repair isn’t expensive. 

OP said dented TWEETER.

not a dust cap, the material of the tweeter's driving face, designed specifically, by computers, by sound analysis in industry designed chambers, to  push air at accurate infinitesimal frequencies, the surface creating the accurate specifically designed polar distribution pattern.

Ye that buy fuses, horribly expensive tweaks, and have the nerve to say, my ears aren/t aged like science says, I can hear highs, I can tell the difference between this and that, 

OMG, stay away from dented tweeters!
