el`Ol, I assume you'd probably cross that BMS 12/horn at around 1kHz. I just wonder how good say the 500 to 1000Hz range will sound when mostly blocked by the horn in front of it.
The woofer response is more rugged in that drivers, but if you compensate it with a DEQX anyway... Real horns usually sound less horny than castrated stuff, so you are more free in the choice of your amplifier. Recently there was a a two way with the 15" version with 6 dB crossover in a German DIY magazine and they liked it. The 12" version is even more "closed", however. The Beyma version is more open.

You're welcome.
One thing I want to add: If you often listen outside the sweetspot I don't expect that perfect polar response from Beyma or BMS as from the Ciare. You will have to consider what's more important for you.

I looked up the test of the 15" BMS coaxial: The 30-Response is 5 dB shifted from 2 kHz on at 30 and the 45 response has nothing in common with the on-axis response from 400 Hz up. And why should one want a coaxial? To let the reflections look like the direct sound.

Oops. Didn't realize the Ciare pro drivers have titanium diaphragm. Probably not my cup of tea. What one could also think about is the 8" BMS. http://bmsspeakers.com/index.php?id=8cn552_overview I listended to the 5" (with a soft-sounding, but powerful amp) and found it tonally very good (Not the freedom of compression one would expect from a pro driver, however.

BMS drivers are difficult to get here and the EU stores are very expensive both for the drivers and shipping, or I would have had some of the 8CN552 a long time ago.

I'll look into that when the time gets closer. The EU stores I tried a while ago, when I was actively interested in this driver were about 2.5x the price of the 8CX21 when all costs were factored in such as shipping and exchange at the time.
