I measure also a lot on loudspeakers for a hobby / commercially and indeed you need a certain distance from a loudspeaker to not measure individual units but the som of the outputs , this is especially he case with larger models like the big wilsons , stereophlle has tested/measurements on a couple of maxx es if you look at those frequency measurements you have an idea if its corresponds with what you hear .
Speakerplacement is also very important ,you can see that in the measurments too
