How to fix Klipsch rattle?

[TWiiii]

We had mounted some Heresys via aircraft cable in a small rec room and found ourselves having to take them down and replace the enclosures due to Klipsch's glue issues in the 80's. Also mounted some Chorus speakers to walls to get the tweeters up to 6 ft and the glue failed and the speakers just slid down the wall fortunately. We glued them back together and remounted them with support shelves. Repairing your speakers designed for home use is going to be a real challenge while maintaing an attractive finish. Good luck
