Von Schweikert Anniversary 5 Mk 1 Tweeter

I damaged the right tweeter moving my VSA Anniversary 5 speakers. The screen is slightly distorted & depressed.

Has anyone repaired/replaced this tweeter? Is it available only from VSA?
IIRC, the VSA uses a ScanSpeak 1 inch Revelator Ring Dome Tweeter. Not sure of VSA does any modification prior to instalation.
Does VSA use the stock tweeter w/o modification? I was also told that you should always change tweeters in pairs if they are not from the same production run. What did VSA say?
