Could glass displace (your fave) tweeter material?

I thought this was pretty interesting.  I do think we pay too much attention to tweeters and not enough to the mids but still I'm always fascinated by the innovation.  Seas has released a new tweeter using a glass dome, and incorporating new faceplate for very smooth off axis response, while maintaining the efficiency of a waveguide.  

I wouldn't be surprised if Joseph Audio was among the earliest adopters.  I understand the Kii range already uses them?

Mass, stiffness, self-damping. Tweeter designers struggle to find a balance between those qualities. I'm not sure glass has much to recommend itself over diamond, beryllium or doped fabric. But then, it depends on the composition of the glass since all glass in not created equal.

Come on Eric you are very knowledgeable about all things audio so I’m sure you know beryllium is only toxic when being machined , sanded or otherwise being physically worked with creating dust or fumes.

I'd love to see someone come up with a dome midrange that could play well throughout the whole vocal range.

At Axpona this year, I listened to some stand mount two-way monitors with both glass diaphragm tweeter and woofer.  I have no idea if the measurements are good but they sounded really nice.

I believe it was by the company GAIT. 6.5 inch glass woofer and 1 inch tweeter.
