I have a pair of JBL 2440 drivers (with aftermarket 2441 diaphragms) which need new damping material inside the back covers. Suggestions?

1/2" closed cell foam adhesive backed. Available in any major city. Use a piece of paper to create a template of the cleaned out back. Be very careful to get no magnetic material like a screwdriver anywhere near the diaphragm as the magnetic field is very strong, especially when unscrewing the internal leads. I paid $20 for a 3' x 6' sheet last year. Canadian, so almost free for you in US!
