I have no experience with large coax drivers but thinking they might be a good solution for my need of a narrow dispersion hifi loudspeaker, but do they have a good midrange and treble?
I think all coax drivers i have seen has more or less poor frequency response linearity, this must be heard as coloration i believe, but can they offer good detail?
Eminence 12cx looks like a cheap and popular driver, but what about sound quality for a modest output level home hifi setup?

Why not just suspend a good Neo tweeter in the centre of your favourite 12" midrange?
Lots of posts about ways to suspend a tweeter, strong thread or thin wires or rigid aluminium bars

Not really cheap, but Beyma 12XA30Nd is great. Beta 12 CX is fine, my project with it is here: Eminence Beta 12 CX + Selenium D210Ti MLTL (huge)
Need to define narrow. If you want laser beam narrow you can array a bunch of small tweeters or tiny full-ranges in a square or circle. Then use an open baffle or U baffle 18" driver with thick cotton insulation behind it.

The Celestion is fine, I have it in my OB.

i have tried that but long time ago, with a small car audio size dome tweeter suspended in front of a 10" midwoofer, the freq response of the tweeter where horrible and the audible effect with tweeter output reflected in the woofer cone was unpleasant, did try with pink noise and listen to where to position the tweeter with no luck. but such tweeter with a suitable horn/waveguide could work though

thank you, i will check them out
A 12" coax isn't going to be all that narrow, is it? The woofer cone is a shallow waveguide.
maybe i am wrong but many larger coax driver seems to give a narrower dispersion then 6" mid + 1" open dome that i am used to
i guess a large midwoofer will beam more then a small midwoofer, and with a tweeter mounted in some kind of waveguide matched to the larger cone will, overall, beam more then what i am used to. i am not sure but i hope this will give me the effect that i am looking for

laser beam is not really what i need, your suggestion sounds interesting but i am not ready to jump on such a new project

Vance Dickason once tested the neo version of that Beyma:

I've used the Ciare 12" coax sold at U.S. Speaker. Sounds pretty damn good and easy to get a flat response out of it.
Just depends how much you want to spend.

Fane TC-250. FR, not coax and pretty amazing.
Perhaps not better than a decent coax, but they are extreme value for the money. Do not think you can find a better coax for that price. And any kind of coax requires more in terms of crossovers.

thank you for the link, nice with measurements and i will try to simulate a crossover for it to see what can be achieved

thank you, that looked very promising indeed, slightly highish qts-value, needs very big cabs as it looks, i will try find off-axis freq curves to see what can be done
