Best loudspeaker with coincident/coaxial driver

A lot of interesting recommendations. I have heard the Gradient speakers in a small room and they sounded very good. They are extremely flexible in the way they can be set up so that they can be placed closer to the walls and corners than most other speakers. I have only heard the YG Carmel and KEF Blade 2 in very large rooms (they sounded quite good), but I think they are certainly contenders. I also like the smaller Raidho stand-mounted speakers. I think all of these speakers can deliver nice, coherent sound, regardless of whether or not they rely on a particular technological approach.

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!

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...
