Nothing is sturdier than a ring radiator

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.

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.

Ok you and I are on the same page
JBL is replaced by the BEYMA Compression Horn tweeter. 
104db sens.
Yes sir, 
She's a  beauty.
any compression horn, does not matter (high fidelity type, not car audio crap) beats any dome, ribbon, etc etc tweeter.
This is what I am trying to get over on this board.
Im my book the only tweeter consideration is compression TI Horn tweeter,,all others do not even exist in my book.
Troels Gravesen is building <,dinasaurs >> in his lab.

Mundorf has requested I test their ATM's, I looked at price and scared me off.
I have no cash for high priced ATM's right now.
Tell ya what I;'ll ask Richard Gray tomorrow, he knows what sonics i am looking for
I'll ask him 
pros /cons of 
Compression vs Mundorf's ATM..
ohhh just cked
91db = dinasaur, its below the <<Golden Threshold>> 94db sens.
+ The price wayyy out my budget. 2 strikes ITS OUT.

<<Higherb Fq response>>>
~~~~~~~~~~
NOt even slight bit interested in the highest registers, My classical cd collection/LP collection has rarelya  few notes in the high fq register, 
Like Richard Gray mentions, 
<<<AMBIENCE>>>
This is the most critical word when discussing tweeters, or any driver for that matter.
I am more than confident to claim as my  mantra
~~~The higher the sensitivity, the superior dynamics = high fidelity will result~~~~~
Audiogon members need to confront the new technology.
Why live in old doctrines and dogmas.
The entire speaker discussion revolves around 1 central concern. 
~~~SENSITIVITY~~~~~
I do not wish to repeat myself over and over 1000 times on this board,
But here it is in a  nut shell
~~~Speakers are everything in a  system, = most critical component~~~~
~~~~Sensitivity rating is everything in a  speaker design/performance/voicing~~~
Speakers Most critical component in any tube system. 
Sensitivity Most Critical in a speaker design. 
My objective is to bring the audiophile community into the 21st Century  by making aware 
 as to what constitutes
a  true high fidelity sound system. 
FR/Compression combo is the 21st Century speaker. 
All else is dinasaur.
