Mike;
That has to be the oldest set of speakers I have seen with a foam hinge/surround, most of the West German sets I have seen have paper ones just like the majority of North American and British sets would. I didn't think that foam became popular until the 70s, and almost ubiquitous with speakers of the 1980sm though some of the latter were actually a rubber. I'm often though that using leather from a chamois might work as a substitute, but then so would cloth.
Regards
Arran
