Up for sale here is this set of 7 plastic parts, which appear to be the diaphragm mounts, from Klipsch K-77 tweeters.  Some have a voice coil in them, but the voice coils appear to be damaged and will not be usable.  I have no idea what the story is here, sorry.  There are also some small metal screens or whatever included.  Please take a look at my pictures, which are the exact item you will receive.

US shipping and handling is $5.  If you have any questions, please ask.

I have more speaker parts and other vintage electronics listed--feel free to take a look!
