Oooh, that's a good choice. They're sensitive and the OP has a big room to fill.
Here's another possibility, and I've heard this setup:
A pair of Magnepan 20.1's plus a pair of JL subwoofers.
The JLs are extremely fast and musical and can keep up with panel speakers. These Maggies have a lot of radiating area and can move a lot of air. The subs provide bass to 20Hz or lower and extend the dynamic range at both ends of the spectrum. This is about the most listenable, musically satisfying speaker setup I've heard. Great imaging and soundstage, great cohesiveness. No boxiness, no bass resonant hump, no screechy highs, no overly forward midrange. Nothing syrupy or slow, no exaggerated zing of a fast but underdamped setup.
