NEARROCK LANDSCAPE LOUDSPEAKERS
SPEAKER PLACEMENT
NEAR ROCK loudspeakers are designed to be placed on the ground, with the grille facing the listening area. The speaker drivers are angled upward to provide proper vertical sound dispersion for listeners standing 10 feet or more away. Sound coverage in the horizontal plane is 100º. Keep this angle in mind when positioning the speakers for stereo reproduction. Too great a distance between any 2 speakers will create a dead spot in the coverage. When in doubt, use additional speakers to ensure adequate coverage.
REFLECTING SURFACES INCREASE BASS OUTPUT
VERTICAL SOUND DISPERSION (45 DEGREES)
10 FEET
HORIZONTAL SOUND DISPERSION (100 DEGREES)
LOW FREQUENCY OUTPUT
NEAR ROCK loudspeakers are engineered to deliver ample bass output in open areas. However, bass output will increase if the speakers are placed near a reflecting surface (such as a wall).

SIX MODEL R8T SPEAKERS CONNECTED IN PARALLEL USING 16W TAPS
NOTE: The total number of speakers multiplied by the tap value cannot exceed the output power (in watts) of the 70V amplifier. The above example shows 6 speakers. Using the 16W taps, you need at least (6) x (16W) = 96W. A good rule of thumb is to select an amplifier with 20% greater power; in this case, an amplifier that delivers about 115W.
EXAMPLE OF 8Ω SYSTEM CONFIGURATION
CAUTION: Nominal system impedance is halved (to 4 ohms) when connecting a second pair of ROCK speakers. Adding a third pair will reduce the impedance load further and could damage an amplifier not designed to operate at impedances below 4 ohms.
Most speaker damage is caused by amplifiers with too little power. An overdriven amp sends clipping distortion to the speakers. Clipping is usually audible; it may vary from a harsh sound to a fuzzy or blurry sound. If you hear clipping at loud volume levels, turn down the volume until the distortion is no longer present. Damage caused by operating the speakers at distorted volume levels is not covered by the warranty.
MAINTENANCE
Speaker cabinets can be wiped clean or even hosed off. CAUTION: Although NEAR ROCK speakers are waterproof, avoid spraying
Observe correct polarity for maximum bass performance. Connect + to + and – to – as illustrated.
