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.
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?

No, I believe diamond tweeters are superior.
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? |
@erik_squires , I agree that this could end up being something big if glass diaphrgms make their way into midrange drivers. Personally I'm hoping to see glass diaphragms in prosound compression drivers, which are sort of like midrange-sized domes with really strong motors. If glass really is (or becomes) a viable alternative to Beryllium, imo that would be huge. |
