The below graphs were taken using my Velodyne SMS-1 as the visual with no EQ adjustments in place. All speakers were calibrated to 73dB's from the Front Center seat. In addition, each sub was calibrated individually to 73dB's as well.
The EP600 was placed back up front centered below my screen and VP150. One 350v3 was placed along the shorter right side wall 6ft from the front wall. The second 350v3 was placed along the left wall about 16ft back next to my second row of seating.
Before I took the pitures, I played with different delay, phase, crossover settings before I found the best results from the main seat.
The pictures are in the following order from each seat; 600 only, 350's only, and finally all subs running. What I've found in all of this testing is that it is very difficult to satisfy all seats in the room, even with multiple subs, or EQ.

Front Center 350s only
Front Center all subs
Front Left 600 only
Front Left 350s only
Front Left all subs
