Well, i have used the coaxial 8cx with good results.
Welcome to Flickr!
The could have done a better job on the throat and the voicecoil is sticking up a little to much.
But for a battery drive partyspeaker they worked out really nice.
I used a minidsp+miniamp.
Then i used autoeq on REW to make them play as flat as possible way past the crossover point.
Applied a seccond order LR at and adjusted delay until the phase looked good.

I went through your results, and one thing that caught my eye was the lack of energy after 10 kHz. Was this a result of your implementation, or is there really nothing to expect after that boundary from these drivers?
I'm currently looking for a suitable 8-10 inch coaxial driver for my open baffle project, and the Oberton 8CX and BMS 8C250 are currently strong candidates for the "next step".
What I'm looking for is a coaxial 8" driver that's good for a project that's looking to destroy anything in the High End of loudspeakers under ten grand. The BMS holds a place close to my heart for anything like this for it's ring diaphragm compression driver, which I have some experience with. So I need much justification to go with the Oberton, which isn't that much cheaper than the BMS...
I can confirm too that Oberton are very good drivers, I used their 12" and 15" with very good results.
Adolf Corkscrew if you have REW installed you can inspect my measurement on the 8cx.

Haven't heard/measured one I still think the Faital 8HX200 might be a suitable candidate for your needs, at least it looks quite nice on paper and also has an annular tweeter diaphragm
Won't be cheap either, that is....
Thanks for the measurements, Nissep. I'll look at these once I get my REW updated.
That FaitalPro is an interesting option. Though this is slipping to the off-topic side of things... Still, I found some measurements that seem to back up the manufacturers datasheet. Expensive, though. Could get a pair of Oberton 8CX for the price of a single FaitalPro. And still have plenty of money for beer left.

I am interested in any data you might have on 12B400. On and off axis frequency response would be great.
Do they match with measured response shown in factory data ?
Thanks
Oberton 10MI 250, 12L Pro (similar to 12L 300) and 15B 450 measured on axis, in the box with front panel recessed so diffraction is present. Anyway, measured frequency response is similar to the factory data.
Sorry, it was so long ago, actually it was 12L Pro, not 12B 400.
