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!

Thank you Soix and Larryi.....Raidho D1 or C1.1 and Gradients are indeed
worthy considerations. Although I find myself leaning just a little toward KEF Blade 2, I am planning to attend RMAF 2015 to listen to most of these contenders before moving forward..
And yes, the VAC Ren Sig 2A preamp and Clayton Audio S2000 class A solid state amplifier are a wonderful combination.... very musical and natural....Please note Clayton Audio is alive and well and now selling direct. Mr Shen builds wonderful class A amplifiers, is great to deal with and stands behind his gear!
Thanks again to all!
Audiobrian-

I will concur w/ Mattmiller. Look no further than Thiel CS 2.7 or CS 3.7 models. This is my reference loudspeaker and it is a killer bargain. Take the left over money and put it into better gear, especially, cables & power cords.

Keep me posted & Happy Listening!
Steen Quatro with carbon tweeter....
Ccherance and EQ bass plus minimal load on your amp.
I am pretty biased tho...last three speakers are from Richard...
You might give him a call and talk about the room..he answers the phone , press 1 and ask for him...
"Zd542, thanks, Vandersteens are wonderful loudspeakers and indeed very coherent, but in a small room with nearfield listening, IMHO a coincident design may make for better driver integration and ease of placement."

I don't see a problem going with a pair of Model 1's or 2's, but if you must have something smaller, look at a pair of ProAc Future 1 or .5's. They work very well in a small room. I'm from NYC so we have a lot of experience with small rooms. As far as coherence goes, the ProAc's aren't quite as good as the Vandersteens, but they are better than my Wilsons, JM Labs, Audio Physic and B&W's of similar price and design. They do a perfect job of blending the ribbon tweeter in with the rest of the drivers.
