I recently acquired a rather rare pair of Yamaha FX-3 speakers, luckily all the beryllium drivers still work but the surrounds on the woofers don't appear to be original to me. Does anyone here know if the speaker surrounds on these woofers were made from the same material (rubberised cloth?) as were used in most of their other woofers from that period? Secondly, where would be the best place to order new surrounds from? I doubt Yamaha would still have replacements after all these years? I am based in South Africa so ideally a place that can ship overseas.
Here's what they look like:
