That does look better Scott. You are getting significant boundary reinforcement in the corner which is why the deep octaves are so loud. The corner placement is also causing more volatile nulls and peaks.

If its practical it may be worth experimenting with placing the sub on the left side of that neat looking entertainment unit between it and the M80. Also check the other side of the entertainment unit. Both spots have less boundary reinforcment. Once there check the phase . You should have more room to calibrate as well.
