Don't know whether I am too late with a suggestion. However, I have a system in a room almost exactly the same size as yours, with similar constraints -- speakers must be close to the wall behind them, room treatments not an options, relatively near-field listening position, etc.
I was planning on Sonus Faber Cremona Auditors at a time when I was also planning Cremonas in another room.
I bought Zu Druids for the 22' x 12' room and Zu Definitions for the other system. The Druid uses a full-range driver plus a supertweeter. There is no crossover -- the signal goes directly to the FRD and the supertweeter is on a high-pass network rolling in at 12kHz as the FRD naturally rolls off.
Zu's speakers are 101db/w/m efficient and the Druids specifically are 12 ohm. They are an 11"w x 6"d x 50"h column on a 12" x 12" base-plate, so their footprint is about what a standmount would be. They can be used very close to the wall and even corner effects are quite limited. You get uniform transient speed, clarity, definition and punch up and down the range from just under 40Hz to 22kHz or so. The Druids can deliver true high-end sound from any of several inexpensive, low power amps, and yet fully justify amplification 10X their cost. Anyway, if you haven't committed, Zu Druids will deliver what you're looking for in a form factor you can assimilate. They are well worth considering.
