The polarity of the FOH/monitor speakers does
matter in this case.
Maybe if mic and speaker are close. But consider a mic that is
5 meters from a FOH speaker. That's 14 ms at the speed of sound.
In each 70 Hz frequency interval there will be one frequency
which returns exactly in phase, no matter what polarity. And
that's considering only the direct path.
