If it's what it says it is, that should be really something. Price is high, but not as high as (true) beryllium

Hopefully we will see other compression driver manufacturers "step-up".
I'd like to see one from 18 Sound (..though I wonder if all their talent was absorbed by B&C).

Looks like Eminence has been working on this for awhile.
New High-Performance Cone and Diaphragm Technology | audioXpress
Article mentions a 3" compression driver in the examples.
This really does look like a nice development in value for large format compression drivers. You can get two for less than the price of a Radian.
Eminence isn't one for hyperbole. The standard version measures well in comparison to the competition and is fairly inexpensive for its category. Their new Tour Grade woofers also compare nicely to the best Italian drivers.

Diaphragm is "lightweight ply carbon".
Looking at the spec sheet you can see the patterns of carbon fiber.
FS 494hz, recommended minimum xo 800hz 12db/oct.
Looking at this driver, I was almost expecting to see xmax and xlim. According to the datasheet, the sensitivity is better than 107db's from 600hz up!
Wow! Could probably match this to a 18" in a two-way, and actually get a good sounding setup.

I just checked the May issue of Voice Coil and it contains a test of that driver by Vance Dickason.

Performance seems very similar to the Oberton ND72HB (another carbon composite driver):
Test Bench: Oberton ND72CT/HB 1.4” Compression Driver | audioXpress
for harmonic distortion and CSD. Bit better frequency response and efficiency though.

Wowzers on that waterfall.....thats Ribbon territory isn't it? I wish I could see the specs for my driver =(
Looks cleaner than this 4" Be driver:

Which horn did eminence use for their test? Their only 1.4 WG is the H14EA. But it doesn’t say exactly.
I wonder what a coat of Aquaplas would do for the standard Radian 745neo. Looks like it would be competitive from the measurements.

Thanks for sharing the tests! I knew it. Amazingly smooth and detailed. No audible distortion down to 490hz with high order crossover + eq at hi-fi listening levels. Dip at 16khz cant really be corrected, but I can't hear it anyway lol.
Not as good as expected, at least from the point of view of measurments, compared to this one, for example: Test Bench: Eighteen Sound ND3ST 1.4” Compression Driver | audioXpress
