Good points - and that might lead me to a smaller screen size which solves a few problems - it would also give me more room on the front wall for speaker placement. I could also probably squeeze the spacing on the seating rows to gain a little more distance to the the screen. I have to maintain access to the service areas behind the seating (HVAC area). It's shown to be a 2' walkway behind the back row riser.

If I place the surrounds on the side walls between the rows then my left surround would have to be over the door. Perhaps on the wall just left of the door. This is planned to be a 5.1 arrangement.

Thanks again for the advice.
