With our magnificently calibrated ears, we walk around and do a Nipper* under each speaker to assess the volume as a crude means of ensuring that all the speakers are connected at the same power level.
*do a Nipper: angle our heads so we can hear better.
Why would you not use a cheap sound meter. Even the app on a smart phone would work well for this. Not calibrating to a precise level, just making sure all levels are relative to each other.
Walking around doing it by ear would invite flaws. Easy to have a speaker off by 1 tap settings and completely miss it by ear.
This assumes that the wire was also tested and the math done for the current draw. Which would also tell you all the tap settings are correct - per design.
