So been super busy lately, but have continued to mess around with the side speakers. I have tried them on the sides and directly against the rear wall and angled towards the MLP. That makes them about 4' from the MLP and 2.5' from the end seating positions. Seems a little better. I also had someone recommend pointing them directly at each other instead of angled toward the MLP. I haven't tried that one yet. Moving them towards the rear also places them directly under the rear heights. Not sure if that is going to cause separation issues.

Starting to think I should have just went 7.1. frown
