Note MCACC, or any such program, may adjust levels to account for room acoustics so the trims might not be equal for all speakers due to other features in the room (proximity of walls and windows, furniture, etc.) as well as variations speaker-to-speaker. Ditto for delay and other parameters. Unless the sound is clearly off with an SPL meter or test tones I would let room correction do it's thing. You can always EQ to taste, but normally these programs get amplitude right and rarely seem to mess up distance. The sound path delay, including electronics, passive crossovers, and such, may cause distance to vary from what you physically measure.
