LANDSCAPE LOUDSPEAKERS
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
additionalspeakers to ensure adequate coverage.
NEAR’s exclusive MDT™ metal-alloy diaphragm is about as light as is physically possible – nearly the ideal
massless piston
. The benefits are immediately recognized in the musical accuracy, fine detail of sound,and ease of listening. Here is a summary of MDT benefits:
•
High rigidity and low mass of metal versus traditional papers and plastics• Extremely
stable cone structure over long periods of time• Fast transmission of sound
through the diaphragm means low energy storage• Special anodizing process creates a ceramic coating for
increased stiffness• Efficient heat-sinking of voice coils under long-term, high-power situations
In addition to MDT, another unique technology is incorporated into NEAR speakers:
Magnetic LiquidSuspension
(MLS™). MLS eliminates the traditional mechanical centering device (the “spider”) for thevoice coil and replaces it with a magnetic fluid that remains
permanently suspended in the gap of themagnet, allowing the voice coil to stay centered and to operate with extreme linearity. In fact, the louder it
plays, the more
accurate the centering forces become. Here is a summary of MLS benefits:• Voice coil is constantly centered as it moves up and down, for
lower distortion• Voice coil is more efficiently heat-sinked by fluid instead of air
•
Dual-layer voice coil with separate inner and outer windings reduces distortion at high output levels•
Greater linearity is accomplished because the mechanical spider is eliminated• Constant lubrication of the gap
prevents oxidation from outdoor use•
Long-term operation is more consistent since fluid doesn't change characteristics•
Longer excursions with smaller diameter woofers; spiders limit excursions
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).
UNDERPOWERING VS. OVERPOWERING
Most speaker damage is caused by amplifiers with
too little power. An overdriven amp sendsclipping 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 volumelevels is not covered by the warranty
.MAINTENANCE
Speaker cabinets can be wiped clean or even hosed off.
CAUTION: Although NEAR ROCKspeakers are waterproof, avoid spraying high-pressure water directly into the speaker grilles.
