Here are the room curves all of which use 1/12 smoothing.
The individual subs responses plus the combination of both before using REW to produce the Harmon curve.
The blue trace below is the same trace as the green trace in the previous graph, before EQ. The green trace below is the EQ'd bass response.
Below is the full frequency sweep in room response for the movie configuration. The red trace is the AVR with PEQ set to FLAT . The blue trace has PEQ turned off.
I don't use the AVR's PEQ function with music. I still use the AVR's bass management in the brown trace where both sub and the towers get bass. The green trace is when the AVR is set to Pure Direct which turns off the bass management and its only the towers producing the full frequency sweep.
