Maybe because current coil formers are good enough. The heating aspect is probably only an issue in pro sound (drivers with baskets that have cooling fins) and the benefit of Be over Kapton et.al. might not be worth the huge extra expense.
And a 6" midrange with a Be cone could be too light and using an expensive metal and setting up production to make something stiff and light for a huge cost just to weigh it down later to meet Fs specs that sell might not be worth it.
It most likely isn’t worth it and thank you for something substantive on the too light idea which does make sense. I’m still interested in the idea of having a former that is literally the same piece of _______ (fill in the blank) as the diaphragm, and how that might have any positive effects on sound.
Has anyone had the luck to listen to several Be tweeters from different brands as ScanSpeak, Bielsma, SBacoustics and has a subjective preference ?
Idem question for the compression drivers with Be diag. ?
I feel for the best, some threads focused on the baffle layout and perhaps rated better drivers that were not Be material, but that were guided, horned and maybe worked as well if not better ? Like some alumin tweeter diag. wave guided, playing with the size both of thz WG and diag. size !
Are there few people that had the luck to benchmark the for real and subjectivly prefer one. The official sponsorised or not or half hided ones, rate a lot the SBacoustics, that is mid priced between ScanSpeak and Bielsma !
thougths and experiences ? (I am to trigger on the more realistic priced SBacoustic ADC to benchmark it with a polymer compression (stupid game, I know !), but who knows ? Should one subscribe a mortgage (better to buy one than several averages ?)

I have used ScanSpeak beryllium dome tweeters. But these are long gone and I have never been too happy with any ScanSpeak drivers. Since a couple of years my main speakers work with Goto SG-160BL tweeters with beryllium diaphragms. And I am familiar with the TAD ET-703.
Objectivity alert: I like the Goto much more.
It seems to be the hot deal with TAD mid drivers to run them all up in two way systems, as is propagated by the maker but I never heard them sound good this way. That always brings that infamous "TADs are grinding my nerves sound". Crossing to a tweeter around 7k5 relaxes things a lot.
