Best loudspeaker with coincident/coaxial driver


I am looking to purchase preferentially a floor-standing loudspeaker with coincident tweeter - midrange for my smaller 14 x 13 ft listening room.
I believe this will enhance coherence and musicality over my Revel Ultima Studio 2, which are indeed quite detailed but don't sound as coherent as I would like in my room. I use VAC preamplification and a Clayton Audio S2000 amplifier.
Thinking about KEF Blade 2, Thiel 3.7, TAD Evolution One and Tannoy DC10A. (Not cheap but perhaps a final loudspeaker?)
Thanks in advance for your comments and reccommendations!

Excellent over-view Yyzsantabarbara.
The Thiel CS is my reference loudspeaker. The only (2) other speakers that I would like to demo someday, are the Sony SS-AR1 and Verity- both cost substantially more in comparison.

I want to read about your thoughts on the Sony SS-AR2 ?

Keep me posted & Happy Listening!
I love Tannoy and have owned some models over the years (Eyris DC3, Dimension TD10, Kensington SE, Canterbury SE), and heard several more. Lots of great speakers there, particularly the Prestige line. But I'd be wary of the 10A and recommend auditioning before buying. I've heard it a few times at my dealer, and the resolution and imaging are fantastic but the energy up top is just too damn much -- searing, in fact. I've heard Tannoys run the gamut from dark to bright and these were the only that were flat out searing to my ears. Yes, you can fight that back down with room setup and gear matches, but from my experience this once is well above the norm up top.
Not sure if they would work for the OP, but Cabasse has an ah hem interesting twist on this idea.
I just remembered that I used to have a pair of KEF speakers that had the tweeter in the center of the driver. Honestly, they were just OK. They were no more coherent than any other well designed speaker I've heard.
Thanks to all respondents! I was unable to attend RMAF but I did audition
the TAD Evolution One, Magico Q1, YG Carmel 2 and the KEF Blade 2, the latter two in my 14 X 13 listening room. The Blade 2 was my winner, in my room. Despite their physical presence, they acted as a small two way monitor as relates to coherence, soundstage, and speaker disappearing act, even in my small room. In this respect I agree completely with Yysantabarbara's post. The Carmel 2 was a very close second, with great coherence, but the soundstage was considerably smaller in comparison. They may not have the very last bit of detail as the Magico Q1 or Revel Ultimate Studio 2's, but in every other way, the Blade 2 bests these in my small room. And I enjoy a "large sound" without the boominess, at reasonable volumes, one might expect from a relatively large floor stander in a small room. There are so many great loudspeakers and I hope to be happy with the Blade 2's for some time! Again, my appreciation to all.
