12' 2" x 11' 4", speakers on the 11' wall. There is a guest bed lengthwise in between the speakers, so they are fairly crammed into the corners. They are a couple feet from the back wall, and flush with the front side of the bed. Imaging is still pretty good, although far from perfect. My chair is backed up to the opposite wall, with a throw blanket on the wall behind me to mitigate reflections. Again, far from perfect, but quite good.
