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?

The bigger Blades do sound bigger and pressurize the room better, the specs on Kef's website are very conservative. 

The big Blades having higher woofers give you less floor bounce which may be the reason they sound less over ripe.

The Blades are really special especially if you drive them correctly. What is the rest of your gear and what part of the world are you in?

Hello Audiotroy, rest of my system consists of Halcro DM10 preamp, and T+A MP3000 HV cdplayer, audioquest wild wood speaker cable.

With this system my BW800 matrixes sound more detailed and effortless louder then before, but much less warm as well (mcintosh mc1000s before with audio research ref40 pre or mcintosh c2300 pre).  

I live in Belgium.

Apart from the cdplayer I heard the blade one with these exact Halcro dm10 and Rowland Model 9t at a dealer, where they sounded good apart from not much low bass... which is the reason I got doubting, since the blade 2s with full electrocompaniet system did produce good bass on the same song but other location; as said big blades in room with sloped side walls and on rollers, blade 2s in huge hotel conference room at high end show and demoed by Kef leading man.

Simce that is based on frequency response and dynamics, they will be practically identical in terms of how good they are at low levels.

My suggestion to demo the Vivid B1 Decade is still in effect. Besides also measureing well, it reviews well too, the SoundStage reviewer stating it’s one of the best he’s ever heard.
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.
