The problem with just adjusting Phase 180 degrees out is that you might one day forget what you did and why. Plus, the speaker might not be exactly 180 degrees out of Phase.
Phase is more related to the distance of speakers as measured from the MLP. It is to keep all of the speakers working together instead of being out of Phase and working against each other.
