INSTALLATION
Cable Type and Gauge
Community recommends stranded, twisted-pair loudspeaker cable. Insulation should be rated for 600
volts or higher. For outdoor installations, choose a cable designed for the application. For permanently installed
systems, a slick, vinyl type insulation is easier to pull through conduit. For portable applications, a rubberized
type insulation is more flexible.
To minimize power losses and optimize amplifier damping factor, keep the total cable resistance under
0.2 ohm. For lengths over 100 feet the wire gauges needed to meet this requirement are usually not practical to
use for both physical and cost reasons. Therefore #10 AWG is recommended as the most practical gauge for
those situations. The run length for both conductors has been figured into the total resistance. Remember that a
lower gauge number means a larger wire size.
