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!

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.
A year later but this is exactly what I have in mind.  Should I get the Blades, keep my Thiel CS3.7's and the Revel Ultima Studio 2's, or a pair of TAD Evolution 1's.  They are all great but my /our house can't handle the divorce payments

Hi paulb6666:

Almost a year later I am still thrilled with the Blades. Still in the same 14 X 13 room.  They are wonderfully coherent and detailed, with satisfying non-boomy bass response.  All 3 speakers are truly excellent but my preference is strongly Blade.  For those who might not be able to squeeze Blade into a budget, the KEF Reference 3 offers 85-90% of Blade's performance at much less cost.
Happy listening!
