New NS-10 woofers

[mullan12]

I bought a pair of NS10s about 10 months ago now and i looked for ages for a pair that were original (wood pulp woofers) and didnt have any signs of wear and tear (white woofers), theyve been going great but just wondering what people know about the newly made woofers that yamaha are putting out. Theres a heap of them on ebay and just seeing if anyone knows what the difference is?
Im in the market for replacement woofers (just incase they ever blow) and just seeing whether I should spend my time finding original wood pulp ones or just get a bunch of the new ones off ebay.

Cheers
