Lots of good suggestions. What's your budget? I recently downsized from a 16x24x10 room to a 13x16x10 room. I had Peak Consult Zoltans that I sold and tried my YG Carmels, but wasn't completely satisfied, even with Tact room correction. I read about and listened to lots of speakers and ended up with Raidho D2, which sound fantastic in this room. They're designed to be listened to in the near field and far apart--farther from each other than from you. The D1 should also work well.
At a cheaper price I also really liked the Larsons, which as mentioned sound good up against the wall. Line arrays don't put out much vertical energy, but many would be rather large for your room. I used Apogees in a room your size with good results, but they'd need to be along the short wall. Also consider some ceiling diffusers that are visually benign. Even though it didn't work for me with my Carmels, I think the room correction route is worth a try. Good luck...
