If you look at the manual for the 2200 or 3300, there are examples of installing in a non-square room, particularly irregularly shaped rooms that are open to a hallway on one side. The picture that shows a TV diagonally placed in a corner is most like mine. Very high ceiling, glass french doors directly to right of TV and at far end where the left side bounces off.
When the family is out of town in a couple of weeks, I will run through the install program again to get it back to the settings prior to my tweaking it a little, then see if I can tweak it better by running through a lot of the options. When running the AIX Records Audio Calibration Disc/HD Music Sampler blu-ray (which I seem to recall came with the Elite TV) to check all channels, I can momentarily hear the sound behind me on the left side when the tone first starts, but then can only hear it in front left side. I don't hear that at all on right rear. Mostly just an increased awareness of a soundstage in the front with nice bass and voice clarity. Again, with my expectations of this rather than surround, I'm happy. If I can make it so I can actually also hear in the 4th & 5th pseudo-speakers behind me or beside me rather than just in an expanded front due to ctr, rt, left, & sub, that would be neat as well but not necessary. I need to find some source great for testing that. Currently, in Avatar when Jake comes off the transport after arriving on the planet, I do remember hearing one of the AMPS (Amplified Mobility Platform Suit?) nicely tromping from right to the left and it sounds like more than just right front to left front speaker transition.
