I used to have an 11'x13' room...best sound I had, after many trys (planar, stand mount, floor standing) were mid-sized, front-ported monitors (Paradigm S2) in a near-field (6' speaker to ear) setup - magical! ...although the Totem Arro was a very close second! Electronics were Naim.
The bigger the speaker, the more challenging it was to shoehorn all that sound into the room and not end up sounding "lumpy".
In the end, "smooth/even" sound won the day.
