The listing is for one gasket. I have them in multiple quantity if needed. Please ask if you need any other used B&W genuine parts. I might get them for you.

This is a gasket which is used under the tweeter (ZZ10111, ZZ13137, ZZ12939, ZZ11541) in any B&W DM601, DM602, DM602.5 S3, DM603, DM604, DM605 Series 1, 2 or 3 speakers.

Might have some signs of use. Please ask if you want to see anything in details. I will try to make more close-up photos upon request.

Will post it by Express Delivery Service. You are welcome to collect if you wish.
