I just picked up a pair of Beovox S35s at a flea market for 10 euros. Type 6311, but they have foam surrounds, not rubber. Not exactly rotten yet, but not much life left either.

Can old foam affect sound quality, even before it's actuallly falling apart?

Who can suggest a good (online) step-by-step guide to refoaming?

Or are these speakers not worth the trouble?

Elsewhere on the forum or look at ebay good_hifi - he has a stepped guide or if memory serves a video

I purchased a kit for a pair of S40s from here.  Kit comes with instructional DVD (20 minutes or so, very good), two surrounds, adhesive, two dust caps (multiple sizes available, you choose at checkout), 3 voice coil shims, a few cotton swabs, and a written instruction sheet.  All for less than $25 shipped priority.  He is in the US but appears to ship internationally.  Kit arrived about 4 days after order.  I have not started the project yet (as I just finished a refurb on a pair of S45-2s) so I can't speak (yet) to whether the kit worked.

The kit did work.
