Have a look at this ebay shop:
http://stores.ebay.de/audio-loeistan_W0QQssPageNameZl2QQtZkm
I just received a couple of the 6 in. JBL Kevlar membranes, supposedly for a JBL GTO 150 driver.
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&category=75779&item=7504522373
Does this driver exist? I couldn't find any on google.
The membranes (or rather: cones) are pretty good quality. I would guess at carbon fibre rather than Kevlar, coated on the back with some sort of (thermoplastic?) black polymer. The surround is definitely not rubber as stated in the offer, it is foam with some glossy coating, and it is not perfectly formed (flange somewhat warped). One has a price sticker from "King Elektronik" and a price in Rupees.
I also received a couple of spiders. They are very, very stiff, and the medium and large ones are extremely poorly centered, with a miscut of up to 2 mm.
I have made some pics but need to find my micro USB cable before I can play them onto the computer for posting.
The cones might be nice for experimentation, the spiders were kind of a flop.
Regards,
Eric

hi
havent been here in diy for a few days - the cones you have got are from kings electronics in delhi - the spiders are stiff as they are intended for driver with a very high total q for use in car audio or cabs which a regular person can build on any size facination he has
