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?

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.

Very cool tech.  Would like to hear real world pros and cons from those who've used them.

Ceramic is a sound tweeter glass is silica made with other components 

diamond by far the most rigid , you internal Xover and capacitors will dictate the tweeter sound have modded Xovers for over 20+ years you want something with a little body for a neutral or bright tweeterlike a Mundorf supreme silver oil which is excellent on top but a little expensive
