Nothing is sturdier than a ring radiator

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.

This is the Vifa clone I have arriving next week.
91db. still too low = old school technology.

Here is a good explanation why AMT aka Ribbons will not work for delivering  high fq's  with high fidelity.
A mid priced  grade  compression tweet wll beat out the highest priced ribbon.
Witha  FR you  can cross high at 10k so you want the best voicing in this critical ambience hz's, which only leaves 1 choice : TI CH (Titanium compression horns). The super high sensivitity makes TI CH a  clean, clear winner.

Here is a good explanation why AMT aka Ribbons

AMTs are NOT AKA ribbons, therefore your premise is bunk. AMTs work on completely different principle, have different motors, vanishingly low distortion and stored energy and impedance characteristics and the conductor and the radiator are not the same material in an AMT. About the only thing they have sort of kind of in common is the effective radiating area is square or rectangular which makes them kind of similar in radiating patterns. If you keep saying AMTs are ribbons, it’s like calling every black car a Mercedes. AMTs are built differently, measure differently, perform differently and are far less delicate than ribbon tweets. Everyone who universally conflates a "ribbon tweeter" with an AMT really has no idea what they are talking about.

In addition to being built entirely differently, the top end Mundorfs have wildly better measurements, including frequency, distortion and lack of thermal compression than a ribbon tweeter. I mention this brand because there are many cheap AMTs which do not perform as well. I’m specifically talking about the high end examples such as from Beyma or Mundorf when I praise their performance.

Try again. And again.
