Hey everybody: I actually came across a more elegant (and cheaper!) solution. Fix the tweeter in place (accidentally) by loosening/tightening the three inner torn screws. The distortion went away! I called Madisound (who sold me the tweeters) and told them what I'd done, and they said it made sense in terms of the design of these tweeters. Seems I fixed it without having to replace anything!
Thanks, though, for all the thoughtful suggestions!
Larry
