For some interesting reading on a unique product using beryllium as the source material for a midrange/tweeter concentric driver (think highly evolved Tannoy), check out the TAD Model 1.

Ultra high-end, cutting edge stuff. The flagship Model 1 lists for $45K and has been met with RAVE reviews at all of the audio shows.
I'm not affiliated with them in any way. Just became aware of their products through meeting their Director of Product Development through an AudiogoN transaction.
Certainly the most unique cabinet and driver design I've seen in a LONG time. 50 layers of laminated 1" high quality birch. Pretty neat stuff.
