speaker set to a smaller value will be quieter than the others. This allows you to
compensate for the environment in which the speaker is placed. For example, a speaker
placed outside would need to be louder than a speaker placed in a small room.

WIRE GAUGES

The following tables show the maximum speaker wire lengths using different gauge wires
for both 4Ω/8Ω and 70V/100V installations.
