Kef Blade or Kef Blade Two for bigger room


Hello all, I am thinking of changing my old bw 800 matrix speakers for the Kef Blade or Blade two.

My living room is 4.8m by 9.3m, with partially sloped high ceeling, and also in the middle going over into my open kitchen adding another 2.5m by 6m... 
Logically I would go for the biggest Blade to get the most and deepest bass response, as most speakers I have tried are too bass shy in my room, except for the big bw800 matrixes, which I set up in middle of the room, and sofa against wall to get bass...
Amplification are Rowland model 9T, so they should get the job done with both speakers.

However I heard from a dealer that the Blade two are better, more coherent sounding, even for bigger rooms; he claimed the big Blade sounds less coherent, with bass floating in the air somewhere and a bit disconnected from the rest...
In my personal experience I heard a Blade two driven by Electrocompaniet Nemos on a music show, im a large rectangular room, and they were brilliant, also in bass.
  i heard the big Blades at a dealer with my model 9t s and they were great as well, but strangely bass shy... room was large enough, but had sloped ceelings to the sides, and the speakers stood on small transporting rollers, so 10 cm higher then normal... Is it possible bass is better from the small blades after all??
Advice would be greatly appreciated! Maybe anyone heard them side by side in same room and with same amps?

mzkmxcv you can't compare the Vivid B1 with a set of Blades, we had the B1 and they were very good they didn't compare to the Blades which just sound bigger with much more deep bass and are much more effortless.

The B1 decade is good for people looking for extreme resolution and don't have giant rooms, we were looking at  the Giya 1 or 2 but felt that were too similar to the Blades at twice the price, the speakers are acutally very similar.

Audiotroy, Kef Blades and Vivid Giya indeed both use the side woofer vibration cancelling arangement. Hower the coaxial midrange tweeter horn loaded in the blade vs the multiple domes in the vivid giyas are very different. Also in crossover topology I think the blades use lower order crossovers then the vivids, which would make for less fase shift to compensate in the blades...
I like the giya 1 and 2, but I was never moved the same way the blades emotionally swept me... and the vivids cost more indeed. 

Thank you for your suggestion mzkmxcv, but the vivid b1 would be lacking in bass for my room.

Audiotroy what do you think in terms of system matching of my set with the blades?
Do you think both blade models sound good on low level listening? I do love a speaker that puts out good bass at low volume levels.

Very few current speakers do that, they all want to win the megawatt race, but forget about low level late night listening, like many of us do, or even normal listening levels. The old matrixes are brilliant at filling a room at low levels as well, I ditched the newer BW 800N just for that reason, no bass at low levels...
" I like the giya 1 and 2, but I was never moved the same way the blades emotionally swept me." Your statement is proof that we all hear things differently. I've listened to KEF Blades and Vivid Giya 1s and to my ears that Vivid's are on a totally different level. They should be due to the cost difference. 
Have to agree with @ricred1  the Blades never wowed me but OMG the Vivid Giya 1 or 2's made me sit up and listen. 
Hey we all listen for different things and hear differently. Granted it's sometimes what we want to hear.
