I can't see that it was mentioned here, so I'd just like to point out that the distances from the speakers and the back and side walls should not be the same. A ratio of at least 1 : 1.3 (measured from the front of the cabinet) is generally recommended to prevent wavelength re-enforcement.
Nice room, btw.
