Steve said "Speakers are AC devices and they have no polarity.".....
This is not true. Although they will work no matter which way you
connect them, there is polarity as it relates to the direction of
speaker cone excursion. Whenever multiple speakers are used together,
or even in the case of a microphone diaphragm and a speaker cone,
polarity does indeed matter. If you have 4 10" speakers in a cabinet,
and two cones are moving in as the others are moving out, you end up
with "phase cancellation" and you lose a huge amount of bass. The
cones all need to travel forward and back at the same time.
