Fountek NeoCD2.0 or NeoX3.0 for 3-way with 8" mid?

Hello forum,

I'm trying to decide which ribbon tweeter to buy for a modification of my current 3-way speaker. The mid driver is a B&C 8NW51. Crossover is handled by software (Acourate by Audiovero with linear phase 200 dB/octave filters and time alignment).

NeoCD2.0
NeoX3.0

While I do favour the higher (claimed) SPL of the NeoCD2.0, I am a little worried about the vertical directivity from a 120 mm high tweeter. NeoX3.0 looks friendler here with 80 mm height, while its width is still a narrow 12 mm. (8 mm for NeoCD2.0).

The speakers are currently playing with a Ciare 1.38TW2 dome tweeter. Sd is 1135 mm² for this 38 mm dome. Both ribbons have 960 mm2, so would be equal to a 34 mm dome.

The 8NW51 can handle 2 kHz without problems, and an even higher crossover point might be possible - but I have to listen to that with a bunch of different filters for a final decision.

Could anybody even compare both ribbons?

Thanks in advance!
