We've generally come to agree on the forum that the main speakers, when positioned for optimal imaging, are not always in the spot that produces the best bass performance. Additional subwoofers are often used to supplement/smooth bass response in this case.
Has anyone experienced the opposite, where the speakers are positioned for optimal bass response and the system/room tweaked for best imaging? I believe it was in reading about the Wisdom Audio in-wall speakers that there was a claim that imaging did not need to rely on speaker position out into the room.
I'm currently of the camp that believes in positioning for imaging, then "fixing" the bass.
