I know that Graz a few years ago was offering pure aluminum (not plastic or kapton backed) ribbons for Duetta midranges, to give them a bit of that pure magic compared with Scinnies. I think I remember individuals saying the result was very nice, but of course, required crossover modification and I can't remember how they affected impedance.
I remember you could walk by Scinnies and see the high frequency ribbon wave around from your body's air movement.
