WIRING INFO - 70V/100V OPERATION
Speaker cable
Wiring speakers for 70V/100V systems is simple and easy. A single run of
2-conductor, stranded wire is run to every speaker location leaving a small
loop (2-3 feet is usually more than sufficient depending on the speakers and
their mounting type) at each speaker location. You can place additional loops
for future expansion or for making speaker location changes if needed.
Note: This is very different from typical low-impedance wiring used for
residential audio installations where a dedicated run of wire goes from each
speaker back to the amplifier/receiver. 70V/100V wiring uses much less wire
and the wire used can be a much higher gauge (thinner wire) even though it is
used in a longer run.
Here is a chart showing some of the differences possible among wire lengths
for both low impedance (4Ω-8Ω) and high impedance (70V/100V) systems:
