Charles, I believe that you're correct in thinking that a large object(such as a TV)situated between the speakers will have some effect in reducing the omni-directionality because of partially blocking the center portion of the reflected sound. To what extent I can't even guess. I've had some experience listening to a colleague's setup which uses Definitive Technology Bipolar speakers(essentially a copy of Mirage technology), but there was no center blockage(the screen, as you suggested, was wall-mounted and served as a reflecting surface). The vagueness of imaging that didn't leave me totally satisfied seemed to be inherent in the design.
