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?

Very nice measurements.   I have my reservations about the DXT waveguide (it's deliberately diffractive), but that has nothing to do with the diaphragm itself.

I would agree with Eric that more attention should go towards the mids. Especially like the dome midrange I see implemented. Mids are the area of sound we hear the most. Tweeters of Ribbon, planar, dome, can all sound good enough when implemented properly.

Agreed w/ Eric on the lack of much new midrange driver development. Much of the good designs today have been around since the 70’s without much change; ATC dome, ESS or similar AMT, planar magnetic, electrostatic, compression w/ horns etc.

No, I believe diamond tweeters are superior.

I wish I liked Accuton sound.  The tech is really interesting.  I just never "warmed up to them."  

My Vimberg Mino D uses Accuton drivers, which was a AXPONA demo purchase. Does Accuton drivers have a “house” sound?  I’ve always thought of Accuton as having increasingly neutral+better performance as one goes up their product line.

@audiokinesis  - AFAIK, the diaphragm itself is made by a 3rd party, so we could be on the verge of several makers producing glass dome drivers. 

Would also be really interested in seeing glass mids. :)  

A major reason I'm pro-glass is that it's not toxic and brittle the same way Be drivers are.  Also, perhaps with advanced molds/processing techniques distortion and ringing could be optimized?
