Do you have some sort of beefkabob with me? I'm just stating the observations I made with me ears. Not claiming any scientific merit behind these observations though others seem to share similar favorable of opinions of the speakers in discussion. In any case very sorry I offended you with my meaningless vocabulary.
I posted this in another thread, but seems more appropriate here:
I used to have the Thiel CS6 which used a coaxial driver arrangement (tweeter mounted in mid). It was generally effective. However I seemed to notice slight interference issues/suckouts if I moved around.
Later I owned the updated Thiel CS 3.7 flagship and currently have the slightly smaller CS 2.7 using the same newly designed coaxial arrangement.
I found the design Thiel achieved with this coaxial fascinating, especially the fact they managed to "flatten" the mid driver to, among other things, reduce the usual reflection problems with a tweeter mounted in the middle. Image here:

Here's Jim Thiel explaining the design at the beginning of this video:
I certainly can't speak to the objective success of the approach. But subjectively both the 3.7 and the 2.7 seem to have hit it out of the park. The mids and highs (and lows!) are the most coherent I've ever heard. I can not "hear out" the tweeter or tell-tale signs of separate drivers or frequency exaggerations at all in the mids/highs and acoustic sounds are just amazingly natural sounding. Image precision and density is the best I've heard anywhere. They also maintain this coherence and even frequency over a seemingly wide range of seating positions. Thiel was a smart dude!
When you look at the amount of effort in development to which KEF and particularly Genelec go to remove all diffraction inducing ridges and obstructions from their coaxial units one would expect this one would be "diffraction city"
I see that from your signature.I am a fan of my Thiel CS3.7 and I have no plans to part with mine for a long, long time.
Such a shame no other company continued the Thiel legacy properly...

I found this review online that has measurement of different coaxials from Fyne/Kef etc:

So far I was interesting in the F502; but its on and off axis (or directivity index) does not look too good:

Any suggestion for a good coaxial loudspeaker in 1-2.5k range?
So far Kef R3 and F502 look interesting.
Thanks for the heads up. Indeed the m106 measures pretty well, but is 3 times the price of the f500 if i recall. F502 with their large 2x8" driver is appealing, cone reaking seems well damped, but frequency response ses a bit ragged
From the new breed of pro coaxial I can recommend the Beyma 12XA30Nd and 15XA38Nd. They don't measure well but they sound very good. It's a diffraction-based tweeter to achieve wider dispersion for a larger sweet spot.
Hi. I built a pair of simple wall mounted open baffles using the C18s, crossing to sealed bass units below 300Hz.
Very nice sounding (and decent measurements too).
Interesting parallel, Have you found something in between the 2 extremes; Studio monitors are fatiguing. Coaxials have their problems.Mostly, the effortless dynamics and the texture detail (some of which might be artificial), apart from the pinpoint yet wide soundstage and quite wide dispersion (due the the diffraction-type of the HF-section). I always compare listening to that kind of coaxials to riding a motorcycle, say, a vintage Harley Davidson in this case. A bit rude at times, but a big joy most of the time, there is a character I can enjoy very much. Whereas a perfect studio monitor like a Neumann KH420 is more like a "precision" touring bike of today. It takes you from A to B as perfect as it gets but alas, not much vibe....
