I have not heard any system where one could say that ideal sound was available in an area that could accommodate more than a single listener. The closest was a big room with omni-directional MBL speakers and a giant horn system in a room that was bigger than 25' by 40'. In both cases, if two people sat really close to one another, the sound was pretty good for both. In my own system, even a few inches of movement one way or the other des affect the sound, particularly the imaging. My system does emloy a horn for the midrange compression driver.
