Nothing is sturdier than a ring radiator

You poke it with your finger. :D 

Be and Diamond tweeters are notorious for breaking apart, so don't do that.

Had that in my JBL 99s many year ago in the mid seventies,Did you know about that then?Also had ESS AMT 3s speakers in the eighties.Got you covered.

Yeah not poking my tweeters with my finger lol and I'm sure most silk domes are pretty sturdy.

OK now we are talking
rated <<94db>>> 
But at a  hefty price.
Tell ya what I have the Vifa clone made by DavidLouis arriving next week, paid like $50/pair.
Interesting tweet.
Vifa's are 91 db. these Scans are $325 EACH!!!!
Considering i will be employing the tweets only for 10k up fq's. , not willing to fork out $700 for top end.
I can geta  pair of compression horns at like 98db = beats Scans 94db
Right now i am all about db level.
db sensitivity is everything ina  speaker, 
93db is my cut off
= Scans' Ring is at 94db. = Compression TI Horn beats it by a  massive db sens margin.
= Scans Ring is borderline old school technology.
