Found these in my basement the other day covered in dust. I don't really know anything about speakers / tweeters but I figured some of you guys from this forum would know what was up. Thanks in advance for any help you can give me.

It's written on the back : ribbon tweeter ( super tweeter ) made by Decca
Super means super high frequencies, when ordinary (old) tweeters failed to give
substantial energy content ( SPL) above 15 kHz.
Probably there's already a crossover inside ( I guess ) so they can be directly paralleled to speaker's terminals, and they were meant to be placed on the top of the enclosure.

Hi there, I can be wrong, but as far as I remember, Mark Levinson used those Decca ribbon tweeters for his incredible audio system, (see here: DIY - HQD Decca Quad ESL 57 Richard Allan | Full range | AudiogoN - The High-end Audio Community), and at that time it was considered the best sounding machine in the world. It was the end of the seventies, long time ago, but I suppose your tweeters still worth something in terms of historic value.
