Soundstage and explosive dynamics?

Although they don't get much press, Lowther speakers set up well do everything you're looking for. They are a very dynamic speaker that absolutely disappear & through a wide deep stage. 

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.
