I would say the tweeter is pristine. However if you look very close, there is a tiny barely noticeable faint mark on the dome. I tried my best to take a macro photo of it, but the camera refuses to pick it up.

The listing is for one single tweeter.

Part number is ZZ10111. This unit is used in all Series 1 B&W DM601 DM602 DM603 DM604 speakers.

The tweeter is fully working and sounds rich and juicy.

Please ask if you need any other used B&W genuine parts. I might get them for you.
