Thinking of Kef Blade 2 to replace Revel Salon 2

Is there a significant difference between the Blades and Blade 2s in a room that is 20' x 26'. Does the Blades sound better and/or require a subwoofer? 

The two speakers sound very similar, the Blade 1 is the bigger of the two and has a bigger overall image and more deep bass. 

Image wise the larger Blade is going to sound more like the big image you get from the Monitors Audio. 

Our demo room is exactly 26 long 20 wide with a 10 foot celing the Blades sound fantastic in that room.

Back to the original topic.  I did get the Blade 2s and the Salon 2s are now sold.  Overall I am happy with the switch.  I was amazed to hear that the Blade 2s completely dominate the Salon 2s in the bass in my room.  I was a little worried that the Blade 2s wouldn't cut it in the bass.  Not the case, they are better over here.  To me the Blade 2s are as good in the tweeter as the Salon 2.  Just not the same transparency and air. That Salon 2 has a great tweeter!  Everything else about the Blade 2 I like better than the Salon 2 though so it's a trade up in my opinion and the looks of the speaker is better to my eye as well.  Such a cool and futuristic art piece that looks great in my room which matters to me a lot.  I can imagine that the Uni Q driver has many mixed opinions about it.  Overall I think the speaker plays music well and I've had many thrilling moments sitting in front of it.  

Please describe the differences between the Salon 2s and Blade 2s regarding space between instruments, the soundstage, imaging, tonality, and dynamics.

ejlif,
Sounds great!   That one brief time I heard the Blades I was blown away.    I really like a cool looking speaker, and the Blades ARE cool looking IMO!
