For that size room a monitor is what is required and if the OP loves the sound of Magneplaner, his best bet is a similar sounding box speaker.
The Jantzens are fantatastic we were a dealer when David Jantzen was trying to figure out the direct vs dealer model. We are no longer a dealer so no conflict of interest.
His Monitors would work great in that size room. The floorstanders have way too much bass.
Guys a 11 * 12 room is tiny and you really can't produce good bass nor would a diapole work well in that size room without a lot of work.
