ELECTRICAL INSTALLATION
block, crimped connections, or wire-nuts. Make sure to provide all connections with a weather-resistant treat-
ment if used outdoors or in potentially harsh indoor environments. This can take the form of a weatherproof junc-
tion box (recommended), do not
remove the gland nut that attaches the cable to the lower rear of the loud-
speaker, as this will compromise the weather integrity of the enclosure. All terminations should conform to local
electrical codes and industry best practices.
Connector Cable Polarity:
The white jacketed conductor is the positive or + signal wire and the black is the negative or – signal wire.
Positive voltage applied to the + wire produces positive acoustic pressure at the mouth of the loudspeaker.
LOUDSPEAKER CABLE
The resistance of the cable that connects the loudspeaker to the amplifier will affect the performance of the
loudspeaker. Cable with too high of a resistance will cause power losses and impair the frequency performance
of the system by reducing the electrical damping factor. To minimize these issues it is desirable to keep the
total cable resistance under 0.2 ohm. However, for lengths over 100 feet, the wire gauges needed to meet this
requirement are usually not a practical choice for both physical and cost reasons. Therefore #10 AWG
(American Wire Gauge) is recommended as the most practical gauge for installations that require 100’ (or
greater) distances.
Both stranded and solid conductors are acceptable, although cable with stranded conductors is often easier to
work with. The length of both conductors has been calculated into the total resistance in the table shown below.
Note that the lower the gauge number, the larger the wire size.
It is always desirable to locate amplifiers as close to the loudspeakers as possible, thereby minimizing the cost
of the loudspeaker cable, as well as reducing the inherent electrical losses that result from long cable runs.
When installed outdoors, cable insulation should be resistant to water, temperature, and ultraviolet exposure.
Recommended cable compositions include polyethylene, neoprene, Teflon™, Silicon™, and Hypalon™.
Cable compositions that are NOT recommended are Rubber, PVC, polypropylene, polyurethane, and nylon.
