I should have paid more attention to this set of requirements. Given these plus your narrow listening area, I think Nola Boxers would be the way to go. A mini is going to be easier to place given the narrow room boundaries than a tower. You can use the $500 saved for stands and cables, or toward a powered sub if desired.
My wants in order of preference are:
-Resolution
-Neurality
-Imaging
-Sound stage width
-Good highs
-Not so slow mids that it'd make listening to heavier music unenjoyable
-A decent amount of bass or even slightly weak on punch is fine
I did, however, remember one more $2K speaker worth checking out, the Atlantic Technology AT-1. Available at $2K/pair, it's a tower with an MTM (D'Appolito) array backed by Atlantic's own H-PAS bass loading system that produces meaningful bass down into the 20s. Stereophile's review and measurements indicated an unusually flat response overall. The MTM array helps keep ceiling and floor reflections out of the image that reaches your ears.
