Need some advice on replacing a B&W tweeter

Well, I just picked up a used B&W LCR60 S3 center channel speaker. I'm a blind guy, and when I was taking it out of the box, I accidently pushed in the dome tweeter..and left a dent on it!!! First of all, I'm extremely pissed off at myself. And second of all, any thoughts on what I should do? I really do take care of my stuff, but when you're blind, sometimes it bites you in the worst way. So I would appreciate any help on this. Can I get buy with a small dent in the tweeter? Or should I order a replacement part? Thanks very much guys...
