I posted this in the speaker forum but I think it fits well here, too. I have a pair of Bang and Olufsen RL 60s. They have this "ABR" (auxillary bass radiator) and the foam that suspends the ABR has rotted away. I know that this has been discussed before, but my question is a little different. Does anyone who has experience re-foaming speakers have any recommendations for a substitute for speaker foam surrounds that I could get as a flat sheet? The prior threads kind of danced around this but I thought maybe someone would have an idea. The original ABRs were suspended by foam, so I'd like to use a foam of sorts, but I don't have a lot of experience here and am wondering if anyone has any ideas for what I could buy as a flat sheet that would pretty much mimic speaker surround foam. Any guesses? So far I have found neoprene foam "skin" but I am concerned that it might be a little too rubbery. The neoprene skin is 1/16" thick. Any thoughts?
