How do they sound? Can't live with it? You are right there are dispersion and distortion problems associated with that kind of problem. The trick above with the vacuum is well known and works but sometimes with aluminum dome tweeters it is not an answer. If you want more info on that trick search the audioasylum.com forum.
I took apart a Hales Revelation 3 some years ago and I think they used Vifa i inch aluminum dome tweeters. Nothing exotic. You can pick them up at speakercity.com. Pull it out and look for identification #s. Give speaker city a call. Lots of Vifa's stuff sells between 35-$60. Important to replace it w/ same tweeter!
Sincerely, I remain
