What the heck is a Linaeum tweeter? How they worked, their use in speaker systems past & present day

[@stonefree1911]

The Linaeum may be the best unknown tweeters around. I wish we could buy them for DYI today. Excellent driver.

I've seen just a couple of photos of Linaeum midranges, which were only used in Linaeum's own expensive speakers.

For the Radio Shack Linaeum line, there was also an Optimus center speaker with a monopole tweeter. They then rebadged (and slightly redesigned) many of them with the RCA label. It's also my understanding that the original Linaeum tweeters used a thinner (and thus lower mass) diaphragm than the RS speakers (which I guess in theory would make it more responsive). I don't know about the Kenwood and Toshiba models. We've discussed these tweeters quite a bit on Audiokarma.
