I have a pair of AR 30Bs a fellow wants to buy from me. Any advice on the best refoam kit for these, or the best method to refoam them?

Measure the maximum diameter that the new foam can have. This is the diameter of the speaker frame measured from flange to flange. Let's call this measurement "O".
Then measure the diameter of the cone and subtract 1/2". Let's call this number "I".
Post these values in this thread. The ideal foam should be a tiny bit smaller than "O" and should be very close to "I".
Also pay attention to whether the attachment of foam to cone is flat or angled. Post this detail as well.

There are a great many foams on the marketplace, and quite often a standard 8" or standard 10" will not work.

You will need to use shims around the voice coil. PLEASE do not omit this step.

At least one major foam retailer sells watered-down glue.

Thanks for the tips. I've used the "Buy the foam, center the voice coil, and go" method in the past, but since I'm actually selling these, I'd rather spend the extra dolllars.
