Overview: The Niles RS8Si
loudspeaker is a two-way, dual tweeter loudspeaker in an acoustic suspension enclosure. The
cabinet is styled to look like a speckled granite rock. It is supplied with a security bracket
and cable to make sure it stays where you put it. The speaker is designed and built
to withstand the environmental stresses placed on an outdoor loudspeaker. The
speaker features a stereo input to allow you to wire the speaker in a
one-speaker stereo or two-speaker stereo configuration.
GeoRealistic Styling: The RS8Si's
enclosure has unique textures and colors to make it look like a natural rock.
The speaker grilles are designed so they blend into the cabinet. The RS8Si is also
available in Granite, Sandstone, and Coral.
Weatherproof: The cabinet is
made from fiberglass; it utilizes double seals on the tweeters, woofer and
enclosure cover. The drivers are designed to drain water away from them and are
made from weather resistant material. The painted aluminum MicroPerf grilles stand
up to the harsh outdoor environment. The speaker has passed test requirements for
salt fog, operating temperature, storage temperature, UV exposure and humidity
per military standard 883.
Dual Voice Coil Woofer: The
RS8Si uses an 8" TCC-filled (Talc, Carbon, and Ceramic) polypropylene woofer. The unusually stiff cone,
the butyl rubber surround and substantial magnet and motor structure are
optimized for large excursions of the woofer. The 8" woofer is designed to
provide rich deep bass and outstanding weather resistance capabilities. Since it
has dual voice coils, the woofer can play in stereo.
Dual Tweeters: The
RS8Si uses two fluid-cooled, 1" Tri-laminate Teteron tweeters that consists of
an inner textile layer which forms the dome, a high damping layer to kill
unwanted resonances, and an outside layer of urethane to add stiffness and
prevent breakups. The result is a transparent clear, natural sounding tweeter which
still maintains its extended frequency response and is completely weatherproof.
Having two separate tweeters allows the cabinet to play in one-speaker stereo
mode or two-speaker stereo mode.
Tweeter Placement: The tweeters
are angled twenty degrees up from the woofer so they are aimed at the listener and
not at the ground. They are also aimed away from each other to improve stereo
imaging if the speaker is wired in the one-speaker stereo mode. If it is wired
in the two-speaker stereo mode, it has ultra-wide dispersion. These features improve the high frequency coverage of the loudspeaker
and ensure that all the benefits of the tweeters are heard and not lost in the
Dual Precision Crossovers: Customized electronic dividing networks inside the cabinet precisely distribute
the music to the woofer and each tweeter. The three-pole, two-way design of the
RS8Si crossover provides excellent stereo imaging into each channel, low distortion and superior
ConeForward Design: This design
mounts the woofer and tweeter as close to the grille as possible giving you
excellent imaging from an outdoor loudspeaker.
Rigid Acoustically Inert Cabinet
Construction: Niles utilizes a unique 4-layer cabinet construction to
achieve superior non-resonance of the speaker cabinet. This insures that all
your hear is the music and not cabinet noise.
Grilles: The aluminum MicroPerf
grilles on the RS8Si have hundreds of precisely sized perforations, creating an
acoustically transparent grille. The aluminum construction resist oxidation
enabling years of trouble-free operation in the harshest of conditions. Niles
paints both sides of the grilles for added protection.
Security Bracket and Cable: The
security bracket and security cable supplied with the RS8Si provides a simple but
effective method to protect your outdoor speaker from theft or unapproved
One-Speaker vs. Two-Speaker Stereo
Modes: The one-speaker stereo mode has the advantage of covering a larger
area than the two-speaker stereo mode. The difference in coverage area is
significant: 4 speakers in the one-speaker stereo mode can cover a maximum area
of 1672 square feet. The same 4 speakers in two-speaker stereo mode can cover a
maximum area of 840 square feet. The trade off between the two configurations is
volume, with the two-speaker stereo configuration being able to play louder in
its area than the one-speaker stereo configuration. Note: The speaker's
impedance will be 8-ohms in the single-speaker stereo mode, while the impedance
will be 4-ohms in the two-speaker stereo mode.
Speaker Cable Connection: To
make sure the speaker connections are trouble-free, the RS8Si features 2 two-foot
connection cables rated for burial underground and specialized waterproof wire
nuts. The wire nuts are filled with a waterproof sealant.
Power Rating: An amplifier
rated at 10 to 200 watts is recommended to power the RS8Si.
2-conductor direct burial cable is recommended at the following sizes depending
on the longest length of cable required:
- 16 gauge: maximum distance
of 60 ft
- 14 gauge: maximum distance
of 100 ft
- 12 gauge: maximum distance
of 160 ft
