one-speaker stereo Mode Vs. tWo-speaker stereo Mode
As can be seen in the coverage examples, the one-speaker stereo mode has
the advantage of covering a larger area than the two-speaker stereo mode. The
difference in coverage area between the one-speaker stereo mode and the two-
speaker stereo mode is significant.
The trade off between the two configurations is volume. The two-speaker stereo
configurations will be able to play louder in their area than the one-speaker
stereo configuration.
Choosing the speaker Cable
In order to choose the proper speaker cable, please follow these steps:
• Unless you are using an impedance matching system, use care when
connecting RS PRO series loudspeakers to your amplifier/receiver. An SI
model wired in single speaker stereo mode will present a 4 ohm load to the
amplifier. All other models and an SI model wired for two-speaker stereo
mode will present an 8 ohm load . Verify the requirements of your amplifier/
receiver prior to making any connections or running any wires.
• You will need 2-conductor speaker cable that clearly identifies each
conductor in the cable. If burying your cable in the ground is required, use
cable rated for direct burial or run cable through PVC pipe. Always use
moisture resistant cable. If you are using an SI model in single speaker stereo
mode, it will require a 4-conductor cable as it needs to carry both left and
right stereo channels.
• After calculating the length of cable needed for each speaker, use the furthest
length cable to determine the gauge (thickness) of speaker wire to use:
Wire Gauge
Maximum Distance
16
60 ft (18 m)
14
100 ft (30 m)
12
160 ft (50 m)
• When running wires inside walls or outdoors, you should install your wires
while conforming to your local building requirements and codes. If you are
unsure of these codes, consult a professional audio/video installer, building
contractor or local building and inspection agency that has jurisdiction.
• If the one-speaker stereo mode is used for this installation, remember that
each speaker uses two separate cables to get their signals. Plan the number
and length of cables, accordingly.
