Soundstage and explosive dynamics?

Spatial Audio’s new reference speaker would certainly be worth a look if you are interested in open baffles. I heard the prototype at RMAF this year and they are pretty special. Right around 10k I think... 

kosst_amojan, you are correct. In a 2 channel setup, you don’t want to call attention to any subwoofer, if you can hear them, you don’t have them setup correctly. They should blend in.
For more on subwoofer setup, check out Jim Smith’s articles on this subject. 

How about the GoldenEar Triton ones for $5k (or $8k if you want to spring for the new Triton reference).

I have them in my living room, with the built in subs they have dynamic range, and they certainly seem to disappear from the soundstage to me.

+1 for ATC's specially their actives, but all ATC's "can" sound a bit cold for some.
Or for something a bit warmer yet still very dynamic with great depyh and sound stage most Wilson Watt/Puppy's, series 7 are my favourites.

Wrong. I just don't fund the claims people make about them to appear in reality. It's like shadorne said; you pretty much have to drive the hell out of them to get the dynamics. No thanks. One of the things I love about my Focals full of 6.5" drivers is they're just about as dynamic at background volume as they are going full bore. To image well a speaker needs to express balanced dynamics at all kinds of volumes, not just screaming loud. 
The OP seemed to demand a very high level of imaging quality, and again as shadorne pointed out, narrow baffle speakers do that very well. I believe it's entirely possible to have excellent dynamics and quality bass in that kind of form factor.
