Ethan, my room is 28'length, 11.5'wide and 9" height. I have a fair amount bass traps on wall-wall and wall-ceiling corners and hi-mid absorbers in side reflection points and ceiling. My monitors are 8" woofer but can go low. After moving the monitors and listening position many times from the 38%, the current position seem to be the best except for 2 nulls. The monitors are as close to the front wall as possible, with a 8" bass trap in between the speaker and wall. The listening position is around the front 30%. Attached are the graphs. What am I missing?
