Help Identify this Grundig Speaker Part

Looking to see if any one can help me identify this 3 x 3 plastic encased speaker part that came out of a Grundig stereo console.

it's an electrostatic tweeter. ... a pair of them. If they don't work they can be rebuilt.

Those are Grundig's electrostatic tweeters. If they're not working, there's a fair amount of info on the web for repars.

Be aware that the leads carry a HV DC polarizing voltage in addition to the signal. Substituting a non-electrostatic tweeter without the proper amp mods will likely smoke it.

Thanks for the info.

I have no use for them nor do I know if they work.

If anyone is interested in them let me know.
