Soundstage and explosive dynamics?

@analogluvr 
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. 

There is a used pair of PMC IB2 is speakers on audiogon currently asking $9,250. 

Problem solved...Full stop!

+1 PMC iB2

Great choice for PMC IB2,
but seems gone now!
is well round sound speaker, tight and fast bass will surprise You.
the sound disappeared even in smaller room and that midrange,man.....kind a miss it!!!

Damn hard to find used at a reasonable price. I’ve posted a few ads over the years looking for a pair of IB2 and MB2 with no luck. Awesome speakers with the right gear!
