INTRODUCTION
The RS PRO series of weatherproof rock loudspeakers are designed to provide
unparalleled listening satisfaction and GeoRealistic™ styling with a design
rugged enough to withstand nature’s fury. The extraordinary sonic performance
of the RS PRO series was achieved by harmonizing Niles’ unique and proprietary
technology with advances in cabinet assembly techniques. They are designed
and built to withstand the environmental stresses placed on an outdoor
loudspeaker. They will sound good and look good no matter what Mother
Nature does to them.
The RS PRO series loudspeaker is a two-way stereo input loudspeaker in an
acoustic suspension enclosure. All of the RS PRO series loudspeakers can be
wired to act as wide dispersion, single channel loudspeakers. Additionally, any
of the SI models can optionally be wired to play stereo sound from a single
loudspeaker. The cabinet is styled to look like a natural rock surface. It is
supplied with a security bracket and cable to ensure it stays where it is placed,
reducing the chance of theft and unauthorized movement of the loudspeaker. For
the rst time, serious listeners will be able to enjoy the music in their backyard as
much as in their living room and the speakers will blend into the landscaping.

FEATURES & BENEFITS
LOOKS NATURAL, SOUNDS GREAT
Traditionally, rock speakers have looked like ornaments and not like rocks.
Each RS PRO series loudspeaker style has unique textures and colors that are
fashioned after natural rocks. Shaped grilles match the features on the front of
the rock, making them blend into the cabinet. All of this extra attention to detail
leads to a GeoRealistic™ style that enables the these loudspeakers to blend in
with other landscaping and disappear. All that will be noticed is the great sound
not the loudspeaker.
WEATHERPROOF CONSTRUCTION
The custom cabinet is made from multi-layer berglass, it utilizes double seals
on the tweeter, woofer and enclosure cover, and is designed so that the woofer
drains water away from it. The grilles are painted rust-resistant aluminum and
the acoustic drivers are made from weather resistant materials. The RS PRO
series loudspeakers have passed some of the most stringent environmental tests
devised. Surviving over 5 years worth of temperature cycling and still having seals
that pass a 24-hour submersion test. They have passed the test requirements
for Salt Fog, Operating Temperature, Storage Temperature, UV Exposure and
Humidity per the stringent military test standard 883. Whether you are concerned
about salt-air, rain, freezing rain, snow, extreme temperatures, high humidity,
direct sunlight or combinations of these conditions, the RS PRO series has
proven itself to withstand the harshest conditions Mother Nature can throw at it.
INJECTION MOLDED TCC WOOFERCOILS
The unusually stiff and light injection molded TCC (talc, carbon, and ceramic-
lled) polypropylene cone, the butyl rubber surround, and the substantial magnet
and motor structure are optimized for large excursions of the woofer. In this way,
the woofer can create superior bass output.
DUAL VOICE COIL WOOFERS (SI MODELS ONLY)
The dual voice coil design of the SI models have the added advantage of being
able to play in stereo when wired in Stereo Input mode.
ADVANCED WEATHER-RESISTANT TWEETERS
In the past, many rock speakers have used a co-axial tweeter design that
has disappointed listeners with a fatiguing and harsh treble sound caused by
tweeter ringing. The advanced 1” Teteron tweeters found in our RS6, RS6SI
(dual tweeter), and RS8SI (dual tweeter) models utilize a tri-laminate design
consisting 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

5
NILES AUDIO – 1-800-BUY-HIFI – 1-760-710-0992
prevent breakup modes. The result is a transparent clear, sweet, natural sounding
tweeter, which still maintains its extended frequency response. The two separate
tweeters of the SI models allow the cabinet to play in one-speaker stereo mode
or two-speaker stereo mode The RS5 models utilize a custom 3/4” Kaladex®
dome tweeter with uid cooling designed for ultra-wide disperson and clear high
frequency response.
TWEETER PLACEMENT IMPROVES COVERAGE AND DISPERSION
The tweeters are angled twenty degrees up from the woofer. The dual tweeters of
the SI models are also angled twenty degrees from each other. This means that
the tweeters are “aimed” at the listener and not at the ground.
DUAL PRECISION CROSSOVERS - SI MODELS ONLY
A customized electronic dividing network inside the cabinet precisely distributes
the music to the woofer and each tweeter, keeping the two channels completely
isolated from each other. The three pole two-way design of the crossover
provides excellent stereo imaging into each channel, low distortion and superior
sonic performance.
CONEFORWARD™ DESIGN
Other rock speaker manufacturers mount their drivers from inside the cabinet.
This moves the front of the driver inside the cabinet creating a tunnel for the
driver to play through. This tunnel adversely affects the sound quality by
making the loudspeaker sound “narrow” and “far away”. Niles’ engineers have
used a proprietary ConeForward™ design technique that moves the woofer
and tweeter as close to the grille as possible. Combining the ConeForward™
design technique with tight manufacturing controls leads to unparalleled sonic
performance and imaging from an outdoor rock loudspeaker.
RIGID ACOUSTICALLY INERT CABINET CONSTRUCTION
Niles utilizes a unique multi-layer cabinet construction to achieve superior non-
resonance of the loudspeaker cabinet. This ensures that all you hear is the music
and not the cabinet ringing.
LOW DIFFRACTION MICROPERF™ ALUMINUM GRILLES
The aluminum MicroPerf™ grilles on the RS PRO series loudspeakers have
hundreds of precisely sized perforations, creating an acoustically transparent
grille. The aluminum construction resists oxidation enabling years of trouble-free
operation in the harshest conditions. We paint both sides of the grille for added
protection.

CONNECTION CABLES WITH WATER RESISTANT WIRE NUTS
Connecting the loudspeaker’s cable to the cable running from the house is
always a point of concern for the installer. If this connection is not done right, the
cable may corrode and the connection may fail. To make sure this connection
is trouble-free, we provide three-foot connection cables rated for burial
underground and specialized waterproof wire nuts. Our wire nuts are lled with a
waterproof sealant. Just insert the wires and twist them together. Then bury the
cable. The connection will be protected from the elements.
SECURITY BRACKET AND CABLE
Using the security bracket and cable supplied with the loudspeaker provides a
simple but effective method to protect the loudspeaker from theft or unapproved
movement. You can easily upgrade our standard security mounting method to
provide even greater security, if you require it.

SELECTING THE NUMBER AND LOCATION FOR YOUR SPEAKERS
The RS PRO series loudspeakers loudspeaker can be installed directly on the
ground, in a owerbed, on a wood deck or on a concrete/stone patio.
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 atter 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 choose 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.

NILES AUDIO – 1-800-BUY-HIFI – 1-760-710-0992
SINGLE SPEAKER STEREO MODE (SI MODELS ONLY)
In one-speaker stereo mode, each connection cable of the SI model loudspeaker
is connected to a separate amplier channel and each loudspeaker cabinet
plays in stereo. This conguration gives you the benet of covering a larger area
than the traditional two-speaker stereo mode. Loudspeakers should be spaced
to properly cover the listening area. The SI models will typically provide proper
coverage for an area 20-30 feet around the front of the loudspeaker (20-24 feet
for the RS6 models and 24-30 feet for the RS8 models).
Figure 1 shows how this would work for a square area using the RS8Si’s in the
one-speaker stereo mode. The loudspeaker coverage pattern is shown in the
diagram.
With the loudspeakers wired in the one-speaker stereo mode you can cover
large areas with the highest quality stereo imaging available.
Figure 1.
Stereo Coverage 4 speakers

8WWW.NILESAUDIO.COM
TWO-SPEAKER STEREO MODE
To obtain the best stereo imaging possible, use stereo outputs from the amplier
and alternate the speakers, left channel speaker, then right, then left, etc. in your
layout. Placing speakers farther apart will lessen sound coverage and require you
to play a louder volume to achieve the same sound level. Placing speakers closer
together will improve sound coverage and produce more stereo coverage. By
utilizing more loudspeakers to cover the area, you can play all of them at a softer
volume and still reach the desired overall sound level. This will avoid having “hot
spots” directly in front of the speakers where the volume is too loud.

NILES AUDIO – 1-800-BUY-HIFI – 1-760-710-0992
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 signicant.
The trade off between the two congurations is volume. The two-speaker stereo
congurations will be able to play louder in their area than the one-speaker
stereo conguration.

connecting RS PRO series loudspeakers to your amplier/receiver. An SI
model wired in single speaker stereo mode will present a 4 ohm load to the
amplier. All other models and an SI model wired for two-speaker stereo
mode will present an 8 ohm load . Verify the requirements of your amplier/

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.

INCORPORATING A VOLUME CONTROL
It is possible to control the volume of the sound at the speaker location. Volume
controls are connected in line with the speaker, an example of wiring an area with
2 speakers and a master volume control is shown in Figures 3a and 3b, 3a is
for one-speaker stereo mode (SI models only) and 3b is for two-speaker stereo
mode. It is usually desirable to control the volume of the speakers in different
areas or zones of the outdoor system. A suggested way to accomplish this is
shown in Figures 4a and 4b, 4a is for SI models in one-speaker stereo mode and
4b is for two-speaker stereo mode.
Niles makes a wide range of outdoor volume controls. We recommend our
standard WVC series models. In addition to controlling the volume of the
loudspeakers, these controls can allow the addition of added speakers
without adding more amplier channels. Volume controls provide exibility and
customization to make the system reliable and easy to use. Consult your local
Niles dealer for more information about using volume controls.

RECOMMENDED AMPLIFIER POWER
We recommend an amplier with a power rating as listed in the specications
page of this manual for optimum performance. Outdoor speakers typically require
more power than indoor speakers. The outdoor environment is usually noisier
and has less reective surfaces to make the system sound louder. Therefore, the
use of a higher power amplier is recommended.
Ironically, most speakers are not damaged by large ampliers but by small
ampliers. When playing the loudspeaker at higher volumes, a small amplier
will run out of power very quickly. When an amplier runs out of power it creates
damaging “clipping” distortion. A large amplier will play at the same volume
without causing this distortion.
See the section “Operation” for more information about clipping distortion.

INSTALLATION
RUN THE SPEAKER CABLE
Determine the location of the amplier that will power the loudspeakers. The
amplier should be located in an area that protects it from the weather. Refer to
the amplier installation instructions to ensure that the amplier is not located in
an area that does not meet its recommended operating environment.
Once the location of the amplier is determined, layout and place the
loudspeakers in the area where music is desired. Use the procedures and
recommendations detailed in the section “Selecting the number and location for
your speakers” of this manual to choose the best locations for the speakers.
Determine a path for the speaker cable. You may need to run wires in walls,
under sidewalks or patios and around obstacles in your yard. Install the 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.
Use care when digging trenches in the yard; ensure that there are no buried
cables or gas lines by verifying the location of these items with the local
authorities in your area prior to digging the trenches.
After selecting this path, estimate the amount of cable needed and use the
section entitled “Choosing the Speaker Cable” to choose and cut the cable
required.
Remember that if you are connecting SI model speakers in the one-speaker
stereo mode, make sure you run two cables to each speaker and that the
cables are clearly identied “Right” and “Left”, so that the stereo imaging of the
speakers is assured.
If the cable will be run underground, dig a trench along the path needed for the
speaker cable. If you are using PVC pipe to run your cable in, connect and glue
the PVC piping sections and connections together so they lie in this trench easily.
Now run the cable from the amplier to each speaker location through the pipe. If
you are using direct burial cable, run the cable from the amplier to each speaker
location and lay the cable in the trench.
Do not cover the cable in the trenches until system operation and loudspeaker
coverage is veried.

CONNECTING THE LOUDSPEAKER IN ONE-SPEAKER STEREO MODE
(SI MODELS ONLY)
1. Strip two to three inches of each speaker cables’s outer jacket away from
the insulated conductors. Ensure that at least two inches of the separate
conductors are free. Do this on both loudspeaker connection cables.
2. Strip one half inch of insulation from the end of each conductor as show in
Figure 5 for both connection cables.
3. Choose the speaker cable that is labeled for the “Right” amplier channel.
Connect one stripped end of the “Right” speaker cable coming from the
amplier to the SI model’s connection cable’s red wire. To connect the two
wires, twist the stripped ends of the wire together and screw down the wire nut
on the twisted wires. The material inside the wire nut will protect the stripped
ends of the wire. However, if added protection is desired, place a large amount
of silicone sealant so the bottom of the wire nut is encased and sealed. Pay
attention to the markings on the speaker cable. Each loudspeaker you connect
must be connected to the amplier’s speaker wire in the same way.
4. Repeat step 3 with the connection cable’s black wire, that is in the same cable
as the wire attached in step 3, and the other stripped amplier “Right” speaker
cable’s conductor.
5. Repeat steps 3 and 4 for the “Left” speaker cable and the connection cable
with the “yellow/black” pair of conductors.
6. Make sure your amplier/receiver is turned OFF before making any
connections. Connect the opposite end of the speaker cable to the amplier
or receiver. Start by performing step 1 and 2 on the speaker cable near the
amplier. Pay attention to the markings on the speaker cable conductor.
Use the cable labeled “Right”and attach the same conductor you attached
to the red loudspeaker wire to the positive (red) or (+) “Right” amplier output
terminal. Attach the other conductor in that cable to the amplier’s “Right”

CONNECTING THE LOUDSPEAKER IN TWO-SPEAKER STEREO MODE
(ALL NON-SI MODELS AND SI MODELS THAT ARE WIRED IN TWO
SPEAKER STEREO MODE)
1. Strip two to three inches of the speaker cables’ outer jacket away from
the insulated conductors. Ensure that at least two inches of the separate
conductors are free. Do this on both loudspeaker connection cables.
2. Strip one half inch of insulation from the end of each conductor as show in
Figure 5 for both connection cables.
3. Connect one stripped end of the speaker cable coming from the amplier to
the loudspeaker connection cable’s red wire of one cable and the connection
cable’s yellow wire. To connect the three wires, twist the stripped ends of the
wire together and screw down the wire nut on the twisted wires. The material
inside the wire nut will protect the stripped ends of the wire. However, if added
protection is desired, place a large amount of silicone sealant so the bottom
of the wire nut is encased and sealed. Pay attention to the markings on the

SPEAKER PHASE
Speaker wire has two conductors. One conductor is attached to the negative
(black) or (-) terminals and one conductor is attached to the positive (red) or (+)
terminals of both the loudspeaker and the amplier. Usually, the wire is marked
for your convenience. There are different ways to mark the conductor; a stripe
on one wire, a ribbed area on one conductor that you can feel, different color
metal conductor wire inside the insulation, the insulation covering the conductor
might be different colors, or there might be a fabric string wound into one of
the conductors. Of course some cables make it difcult to determine which
conductor is which. Be careful to avoid mistakes. If you do, one loudspeaker
will be playing out of “phase” with the other loudspeaker. An out of phase pair
of speakers work against each other and the sound of the two speakers playing
together will be lacking in bass response and have a “phasey” sound quality. If
you suspect the sound is not right, check to make sure that the conductors on
each loudspeaker are attached the same on the loudspeaker and the amplier. If
you cannot see any markings or determine if they are all attached the same, try
this simple test:
IN ONE-SPEAKER STEREO MODE (SI MODELS ONLY)
1. Play some music with the amplier or receiver set to Mono.
2. Stand in the middle of both speakers and about three feet away from them..
Listen to the richness of the bass and the loudness of the sound.
3. Turn off the amplier and reverse the connections on one side of the speaker
only.
4. Repeat the listening test with the same setting of the volume controls. If the
current sound has a richer bass and is slightly louder than the previous sound,
the speakers are working together and are “in-phase”. Leave the speakers
connected to the amplier in this conguration. If the current sound is not
richer in bass or louder than the previous sound, turn off the amplier and
reverse the connections of the wire you moved in step 3.
5. Check the phase between each speaker in the area by following the
procedures for two-speaker stereo mode. Remembering to change the phase
on both sides of the speaker when you perform step 4 of that procedure.

16 WWW.NILESAUDIO.COM
IN TWO-SPEAKER STEREO MODE OR
CHECKING PHASE BETWEEN SPEAKERS
1. Point the speakers at each other, rather than at the area you want to cover.
2. Play some music with the amplier or receiver set to Mono.
3. Stand so you are the same distance from each speaker and listen to the
richness of the bass and the loudness of the sound.
4. Turn off the amplier and reverse the connections on one speaker only.
5. Repeat the listening test with the same setting of the volume controls. If the
current sound has a richer bass and is slightly louder than the previous sound,
the speakers are working together and are “in-phase”. Leave the speakers
connected to the amplier in this conguration. If the current sound is not
richer in bass or louder than the previous sound, turn off the amplier and
reverse the connections of the wire you moved in step 4.
VERIFY SYSTEM OPERATION AND LOUDSPEAKER COVERAGE
1. Turn the system “On” and play music to the speakers. Set the Volume controls
to a level that allows the speakers to be easily heard over the “noise” in the
area.
2. Verify that music is playing through each speaker. If not, troubleshoot the
wiring and make sure each speaker is electrically connected to the amplier.
3. Verify that each speaker is connected to the proper channel of the amplier.
To do this, change the balance of your speakers on your amplier or receiver
so that one channel is at playing loudly and the other is not. Verify that each
speaker or each side of the speaker is attached to the proper channel of the
amplier. If they are not, correct the wiring on the loudspeaker that is not
connected properly. Reset the balance on the amplier or receiver so both
channels have a similar volume level.
4. If you used a volume control between the amplier and the speakers, verify
that it is controlling the volume of the loudspeakers in its zone. Repeat this for
every volume control in the system. If any are not, correct the wiring.
5. Point the loudspeakers per the layout and verify that the sound is even and
consistent throughout the area.

INSTALLING THE SECURITY BRACKET AND CABLE
1. With the loudspeaker in the proper location, turn the loudspeaker over so the
bottom of the loudspeaker is facing you, as shown in Figure 6.
2. Take the nylon security cable, supplied with the loudspeaker and fold it in half.
Using the middle of the cable, feed it through the Security Attachment Eyelet
as shown in Figure 7.
3. Feed the opposite end of the nylon security cable through the exposed portion
of the cable that was just fed through the security eyelet, as shown in Figures
8 and 9.
4. Pull the ends of the security cable with the
loops as tight as you can until the knot around the
security eyelet is tightened as shown in Figure 10.
5. Feed the Security Stake through the loops at

NILES AUDIO – 1-800-BUY-HIFI – 1-760-710-0992
TO INSTALL AN UPGRADED SECURITY SYSTEM:
1. Prepare a hole that is at least one-foot deep, at a minimum (three-feet if the
speaker is being installed in an area that has a frost line). The hole should be at
least six inches in diameter. This hole should be under the desired location of
the loudspeaker.
2. Once the hole is prepared, mix the concrete per its instructions. Fill the hole
with concrete. Place the concrete anchor in the center of the concrete so the
top of the anchor is ush with the top of the concrete and the anchor is not
lled with concrete.
3. Wait until the concrete is dried per the instructions on the concrete mix used.
4. Screw the stainless steel eyebolt into the concrete anchor
5. Feed one end of the stainless steel aircraft cable through the eyebolt in the
concrete
6. Loop the end of the aircraft cable around the eyebolt and back to the aircraft
cable. Secure this end of the cable to the main aircraft cable with the wire rope
clamp.
7. Turn the loudspeaker over and feed the other end of the aircraft cable through
the eyelet in the bottom of the loudspeaker.
8. Loop this end of the aircraft cable around the eyelet and back to the aircraft
cable. Secure this end of the cable to the main aircraft cable with the wire rope
clamp. The upgraded attachment should now look like Figure 13.

FINAL ADJUSTMENTS
Now that the loudspeaker’s phase, operation and security is assured, there are
some nal steps to ensure that the loudspeakers installation is complete and that
they are used at their full potential.
1. Cover any trenches or wires that are still open or exposed.
2. Point the loudspeakers per the layout and verify that the sound is even and
consistent throughout the area that sound is desired, as you did in step 5 of
verifying system operation.
3. Verify that the front of the loudspeaker is as close to perpendicular to the
ground as possible. This will aid the drainage of water away from the woofer
and improve sound quality.
4. Check that the entire installation is safe and secure.
OPERATION
LISTENING AT HIGHER VOLUMES
Outdoors there are no walls to reect and contain the sound and typically the
ambient noise level is louder. This causes the system to require more power to
achieve a reasonable listening level than it does when you are listening indoors.
In addition, you are frequently further away from the loudspeaker. It is possible
to turn the volume so high that the amplier runs out of power. This creates
”clipping” distortion.
Clipping distortion makes treble sound very harsh and unmusical. When you
hear harsh sounding treble from any good speaker indoors or outdoors, turn the
volume down immediately! Those harsh sounds are masking some much more
powerful ultra-high-frequency sound spikes that will quickly damage any ne
loudspeaker.

The rock loudspeaker should not require cleaning. The formation of dirt and
molds on the cabinet will add to the natural look of the loudspeaker. However, if
you desire to clean the loudspeaker you can clean your RS PRO series
loudspeaker with a dampened soft cloth or a paper towel. Hosing the
loudspeaker off with a garden hose or high pressure cleaner is not
recommended, the drivers, especially the tweeter, can be damaged by a high-
pressure stream of water. The use of chemical cleaners should also be avoided.
