Please tell me what do you think and problem areas
OK, a few comments.

Normally it's best to use a vertical axis scale from 45dB to 105dB and a horizontal scale from 15Hz to 200Hz on all your graphs. This provides a consistency for interpretation for everyone. You can set the axis with the Graph Axis Limits button.

The phase control only has an effect when a sub and mains are played together. It has no effect when playing the sub alone.

Looks like the sub has the smoothest transition when its phase is at 180. The sharp dip won't be audible.

Unfortunately room treatments have very little effect on peaks and valleys at subwoofer frequencies <80Hz. For the low sub frequencies equalization is required.
