Maybe I should add that there are good coaxials out there but no one can buy them for DIY purposes?
There are plenty of coaxials on offer:

I'd say a few of them are available and quite nice.
I have hands on experience with TB W6-2313, which a very nice driver and a beast at imaging. Quite impressive.
I did not try the SBA SATORI MT19CP-8 myself yet, but I am quite sure it is a wonderful driver as well. SBA doesn't have many duds in their lineup. It's on my very short list of drivers to try.
The new W6 and W8 TB line of coax is very nice. Another set has been used in X's TL design and has the owner liking them very much.
SBA, I'm sure, is just as good. I should be able to prove it soon.
So, yes, there are good coax out there.
The TB drivers are exceptional as far as coaxials go. I would love to hear a comparison of their coaxials and their full ranges. That would be interesting. I wish I could come up with a couple grand to do that experiment.
Here is the typical Coaxial FR from the Satori MT19CP-8 Coaxial with Papyrus Cone. This kind of data scares me away from attempting to build a coax system. The frequency response above 2K is horrible.
I think there is a lot going on there that an average hobby hifi guy like me can't fix. The coaxial TB graphs are much better.
Here is a somewhat over-smoothed but much flatter looking frequency response from the W6-1916 6.5" Paper Full Range. Interesting to note that the TB coaxials also 'measure' very smooth. The TB frequency smoother is well known. This speaker is something the average guy can plop in a box and have reasonably good sound straight away.
This doesn't take into account the difficult to measure aspects of "cymbals appearing in the speaker cone" and "sound stage" that people can hear but modern machines for some bizarre reason can't measure. I think illusion and psychology are stronger factors than measured data. That's just my observation, don't go losing your mind and tell me I'm ignorant and don't understand physics.
My experience with several SEAS coaxials I admit is dated, the new designs from different manufacturers show promise, especially the TB offerings that seem to be well designed. They appear to be a system, not a tweeter stuck on a woofer. They appear to resemble other 'high-end' designs.
One last point before I hop on my tractor, there are planar loudspeakers that produce wide frequency response and are quite remarkable when you think about it. There are some rather large geometry differences, but I don't see why a cone can't be a good full range too.
