Niles Audio CORAL RS6 - Manual (Page 8)

Figure 3 shows the difference in coverage area using the spacing rules for mono
signals. Using the same four speakers as we did in Figure 1, we can increase
our coverage area from 875 square feet (81.3 sq. meters) to 1400 square feet
(130.1 sq. meters), simply by using a mono source.
The trade off in sound quality between mono sources and stereo sources is sonic
imaging. If you are concerned with keeping the instruments and vocals sonically
separated, then stereo setup must be used.
When choosing the location for the loudspeaker, take into consideration the slope of
the land in the area the speakers are going to be placed. The flatter and more level
the area, the better. The woofer should be straight up and down or tilted forward a
bit to assist in drawing water away from it. Never chose a place where an automatic
sprinkler will be aimed on or near the loudspeaker. While the loudspeaker is
weatherproof, continuous streaming water will shorten the product’s life.
Choosing the Speaker Cable
In order to choose the proper speaker cable, please follow these steps:
• Unless you are using a Niles’ WVC100 or WMVC100 series weatherproof
impedance matching volume controls or equivalent, only two (2) RS6
loudspeakers can be safely attached to a typical amplifier channel, if that
amplifier is rated to drive 4 ohms. You can do this by running wires from each
loudspeaker to the amplifier or you can connect one loudspeaker to another.
Make sure this is taken into account when calculating cable length and number
of amplifier channels needed. If you are unsure about these calculations, consult
an audio/video installer.
