INTRODUCTION
The RS8Si series of weatherproof rock loudspeakers are designed to provide
unparalleled listening satisfaction and GeoRealistic™ styling. The extraordinary
sonic performance of the RS8Si 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 RS8Si series loudspeaker is a two-way stereo input loudspeaker in an acoustic
suspension enclosure. The loudspeaker can be wired to play stereo from one
cabinet or act as a wide dispersion single channel loudspeaker. The cabinet is
styled to look like a rock. It is supplied with a security bracket and cable to insure it
stays where it is placed, reducing the chance of theft and unauthorized movement
of the loudspeaker. For the first time, serious listeners will be able to enjoy the
music in their backyard as much as 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
RS8Si 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 RS8Si to blend in with other landscaping and disappear. All that will be
noticed is the great sound not the loudspeaker.
Weatherproof Construction
The cabinet is made from fiberglass, it utilizes double seals on the tweeter, woofer
and enclosure cover, the woofer drains water away from it, the grilles are painted
aluminum and the drivers are made from weather resistant materials. The RS8Si has
passed 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. It
has passed the test requirements for Salt Fog, Operating Temperature, Storage
Temperature, UV Exposure and Humidity per military test standard 883. Whether
you are considered about salt-air, rain, freezing rain, snow, extreme temperatures,
high humidity, direct sunlight or combinations of these conditions, the RS8Si has
proven itself to withstand the harshest conditions Mother Nature can throw at it.
8" Injection Molded TCC Woofer with Dual Voice Coils
The unusually stiff and light injection molded TCC (talc, carbon, and ceramic-filled)
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 8"
woofer can create superior bass output. Since it has a dual voice coil, it has the
added advantage of playing in stereo. In the end, the woofer design combines
deep rich bass and outstanding weather resistance capabilities with the ability to
play in stereo.
Dual 1" Teteron Tweeters
In the past, 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
RS8Si’s dual 1" Teteron tweeters 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 prevent breakup
modes. The result is a transparent clear, sweet, natural sounding tweeter, which still
maintains its extended frequency response. Having two separate tweeters allows the
cabinet to play in one-speaker stereo mode or two-speaker stereo mode.
Tweeter Placement Improves Coverage and Dispersion
The tweeters are angled twenty degrees up from the woofer. They are also angled
twenty degrees from each other. This means that they are “aimed” at the listener
and not at the ground. They are aimed away from each other to improve stereo
imagining, if the loudspeaker 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 1" Teteron Tweeter are heard and not lost in the surroundings.
Dual Precision Crossovers
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 RS8Si 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
patent-pending ConeForward™ design technique that moves the woofer and
tweeter as close to the grille as possible. Combining the ConeForward™ design
technique with tight quality control leads to unparalleled sonic performance and
imaging from an outdoor rock loudspeaker.
Rigid Acoustically Inert Cabinet Construction
Niles’ utilizes a unique 4-layer cabinet construction to achieve superior non-
resonance of the loudspeaker cabinet. This insures that all you hear is the music
and not the cabinet ringing.
Low Diffraction Microperf™ Aluminum Grilles
The aluminum Microperf™ grilles on the RS8Si 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.
Dual 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 will
corrode and the connection will fail. To make sure this connection is trouble-free,
we provide two three-foot connection cables rated for burial underground and
specialized waterproof wire nuts. Our wire nuts are filled 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.

INSTALLATION CONSIDERATIONS
Tools and Materials Required
• A wire stripper
• 1/2" PVC conduit (optional)
• PVC conduit glue and cleaner (optional)
• PVC cutting tool
• Trench digger or shovel
• Tube of silicon sealant (optional)
• Cable (length and type determined by installation site – see “Choosing the
Speaker Cable”)
Selecting the number and location for your speakers
The RS8Si loudspeaker can be installed directly on the ground, in a flowerbed, on a
wood deck or on a concrete/stone patio. There are three considerations for placing
the loudspeaker; connecting each cabinet in one-speaker stereo mode or two-
speaker stereo mode, ease of running the cable to the loudspeaker and coverage of
the loudspeaker. The RS8Si loudspeaker will cover an area of a circle with a 22-foot
diameter, in front of the speaker.
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.
Single Speaker Stereo Mode
In one-speaker stereo mode, each connection cable of the RS8Si loudspeaker is
connected to a separate amplifier channel and each loudspeaker cabinet plays in
stereo. This configuration gives you the benefit of covering a larger area than the
two-speaker stereo mode. The loudspeakers can be spaced 11 feet from the sides of
the listening area and 22 feet from each other. The row spacing between speakers
should be less than 38 feet. These loudspeaker spacing rules are the recommended
maximums; placing speakers at a greater distance apart will negatively affect sound
coverage and produce spots within the listening area where the sound quality
will be poor.

Figure 1 shows how this would work for a square area of 44 feet by 38 feet and
using the RS8Si’s in the one-speaker stereo mode. The loudspeaker coverage
pattern is shown in the diagram.
Figure 1 Stereo Coverage 4 speakers
With the loudspeakers wired in the one-speaker stereo mode you can cover large
areas with the highest quality stereo imagining available.
Two-speaker Stereo Mode
In this mode, each loudspeaker will have one amplifier speaker cable connected to
both loudspeaker connection cables and it will take two loudspeakers to play in
stereo. To obtain the best stereo imagining possible, use stereo outputs from the
amplifier and alternate the speakers, in your layout. You should place speakers less
than 11 feet from the sides of the listening area and 18 feet from each other. The
row spacing should not be greater than 28 feet. These loudspeaker spacing rules are
the recommended maximums; placing speakers at a greater distance apart will
negatively affect sound coverage and reduce their stereo effect. Placing speakers
closer together will improve sound coverage and produce more stereo coverage.

Figure 2 shows how this would work for a square area of 35 feet by 28 feet
and using stereo signals. Using our spacing rules as shown in Table 1, leads
to the need for four speakers. The loudspeaker coverage pattern is shown

have a more even sound level across the listening area. This illustrates the fact that
not using the maximum spacing allowed leads to improved sound quality.

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 significant. Four speakers in the one-speaker stereo mode
can cover a maximum area of 1672 square feet (155.3 sq. meters). The same four
speakers in two-speaker stereo mode can cover a maximum area of 840 square feet
(78.0 sq. meters).
The trade off between the two configurations is volume. The two-speaker stereo
configurations will be able to play louder in its area than the one-speaker stereo
configuration.
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 halves of an RS8Si
loudspeaker can be safely attached to a typical amplifier channel, if that amplifier
is rated to drive 4 ohms. This means that two loudspeakers can be attached to an
amplifier channel in the one-speaker stereo mode or one loudspeaker can be
attached in the two-speaker stereo mode 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.
• You will need 2-conductor speaker cable that clearly identifies each 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.
• After calculating the length of cable needed for each speaker, use the furthest
length cable to determine the gauge (thickness) of speaker wire to use:
Wire Gauge
Maximum Distance
16 . . . . . . . . . . . .60 ft (18 m)
14 . . . . . . . . . . . .100 ft (30 m)
12 . . . . . . . . . . . .160 ft (50 m)
• When running wires inside walls or outdoors, you should install your 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.
• If the one-speaker stereo mode is used for this installation, remember that each
speaker uses two separate cables to get their signals. Plan the number and length
of cables, accordingly.

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 4a and 4b, 4a is for
one-speaker stereo mode and 4b 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 5 and 5b,
5a is for one-speaker stereo mode and 5b is for two-speaker stereo mode.
Niles makes a wide range of outdoor volume controls. We recommend our
standard weatherproof volume control, WVC100 series or our weatherproof muting
volume control, WMVC series. In addition to controlling the volume of the
loudspeakers, these controls can allow the addition of added speakers without
adding more amplifier channels. Volume controls provide flexibility 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 amplifier with a power rating of ten to two hundred watts per
channel for optimum performance. Outdoor speakers typically require more power
than indoor speakers. The outdoor environment is usually noisier and has less
reflective surfaces to make the system sound louder. Therefore, the use of a higher
power amplifier is recommended.
Ironically, most speakers are not damaged by large amplifiers but by small
amplifiers. When playing the loudspeaker at higher volumes, a small amplifier will
run out of power very quickly. When an amplifier runs out of power it creates
damaging “clipping” distortion. A large amplifier will play at the same volume
without causing this distortion.
If the plan requires connecting two halves of a RS8Si speaker to an amplifier, in the
one-speaker stereo mode or use the speaker in the two-speaker stereo mode, an
amplifier rated to drive a 4-ohm load of thirty watts to three hundred watts, is
recommended. If you use two halves of an RS8Si’s on one channel and the
amplifier is not rated for driving a 4-ohm load, the amplifier will run out of power
more easily and could damage the speakers.
See the section “Operation” for more information about clipping distortion.

INSTALLATION
Run the speaker cable
Determine the location of the amplifier that will power the loudspeakers. The
amplifier should be located in an area that protects it from the weather. Refer to the
amplifier installation instructions to ensure that the amplifier is not located in an
area that does not meet its recommended operating environment.
Once the location of the amplifier 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 the speakers in the one-speaker stereo mode,
make sure you run two cables to each speaker and that the cables are clearly
identified “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 amplifier to each speaker location through the pipe. If you
are using direct burial cable, run the cable from the amplifier 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 verified.
Connecting the loudspeaker in one-speaker stereo mode
1. Strip two to three inches of each 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 6 for both connection cables.
Download from Www.Somanuals.com. All Manuals Search And Download.
11
3. Choose the speaker cable that is labeled for the “Right” amplifier channel.
Connect one stripped end of the “Right” speaker cable coming from the amplifier
to the RS8Si 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 silicon 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 amplifier’s speaker wire in the same way.
4. Repeat step 3 with the RS8Si connection cable’s black wire, that is in the same
conductor as the wire attached in step 3, and the other stripped amplifier “Right”
speaker cable’s conductor.
5. Repeat steps 3 and 4 for the “Left” speaker cable and the RS8Si’s connection
cable with the “yellow/black” pair of conductors.
6. Connect the opposite end of the speaker cable to the amplifier or receiver. Start
by performing step 1 and 2 on the speaker cable near the amplifier. 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” amplifier output terminal. Attach the other
conductor in that cable to the amplifier’s “Right” negative (black) or (–) amplifier
output terminal.
7. Using the cable labeled “Left” attach the same conductor you attached to the
yellow loudspeaker wire to the positive (red) or (+) “Left” amplifier output
terminal. Attach the other conductor in that cable to the amplifier’s “Left”
negative (black) or (–) amplifier output terminal.
Connecting the loudspeaker 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 6 for both connection cables.

3. Connect one stripped end of the speaker cable coming from the amplifier to the
RS8Si connection cable’s red wire of one cable and the RS8Si 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 silicon 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 amplifier’s
speaker wire in the same way.
4. Repeat step 3 with the RS8Si connection cable’s black wires and the other
stripped amplifier speaker cable’s conductor.
5. Connect the opposite end of the speaker cable to the amplifier or receiver. Start
by performing step 1 and 2 on the speaker cable near the amplifier. Paying
attention to the markings on the speaker cable conductor, attach the same
conductor you attached to the red loudspeaker wire to the positive (red) or (+)
amplifier output terminal. Attach the other conductor to the amplifier’s negative
(black) or (–) amplifier output terminal.
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 amplifier. 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 onto one of the conductors. Of course some
cables make it difficult 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 amplifier. If you cannot see any markings or determine if they are all attached the
same, try this simple test:
In one-speaker stereo mode
1. Play some music with the amplifier or receiver set to Mono.
2. Stand in the middle of each speaker and three feet away from it. Listen to the
richness of the bass and the loudness of the sound.
3. Turn off the amplifier 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
amplifier in this configuration. If the current sound is not richer in bass or louder than
the previous sound, turn off the amplifier 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.
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 amplifier 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 amplifier 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
amplifier in this configuration. If the current sound is not richer in bass or louder
than the previous sound, turn off the amplifier 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, trouble shoot the wiring
and make sure each speaker is electrically connected to the amplifier.
3. Verify that each speaker is connected to the proper channel of the amplifier. To do
this, change the balance of your speakers on your amplifier 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 amplifier. If they are not,
correct the wiring on the loudspeaker that is not connected properly. Reset the
balance on the amplifier or receiver so both channels have a similar volume level.
4. If you used a volume control between the amplifier 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 it is 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 7.
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 8.

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 11.
5. Feed the Security Stake through the
loops at the end of the security cable
and insure that they are inserted into the
cable holder provided at the top of the
stake, as shown in Figure 12.

7. Pull on the security cable and verify that the stake is securely held in the ground.
Upgraded Security Attachment Method (Optional)
To perform this attachment method you will need the following items:
1. (1) Stainless Steel Eyebolt
2. (1) Concrete Anchor sized to the Stainless Steel Eyebolt
3. (1) Bag of Quikcrete – fast drying cement mix or equivalent
4. A post hole digger or shovel
5. (1) Stainless Steel Aircraft Cable 1/8" diameter or larger
6. (2) Stainless steel wire rope clamps sized to the aircraft cable chosen
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 flush with the top of the concrete and the anchor is not filled
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 14.

Final Adjustments
Now that the loudspeaker’s phase, operation and security is assured, there are some
final steps to ensure that the loudspeakers installation is complete and that they are
used at there 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 reflect 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 amplifier 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 fine loudspeaker.
Cleaning
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 the RS8Si 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.

5 YEAR LIMITED WARRANTY
Niles Audio Corporation (“NILES”) warrants its rock loudspeaker products to the original
purchaser to be free of manufacturing defects in material and workmanship for a period of five
years from date of purchase.
This Warranty is subject to the following additional conditions and limitations. The Warranty
is void and inapplicable if NILES deems that the product has been used or handled other than
in accordance with the instructions provided by the manufacturer, including but not limited to
damage caused by accident, mishandling, improper installation, abuse, negligence, or normal
wear and tear, or any defect caused by repair to the product by anyone other than NILES or an
authorized NILES dealer.
To obtain warranty service, take the unit to the nearest authorized NILES dealer, who will test
the product and if necessary, forward it to NILES for service. If there are no authorized NILES
dealers in your area, you must write to NILES and include your name, model and serial
number of your unit, along with a brief description of the problem. A factory Return
Authorization Number will be sent to you. DO NOT RETURN ANY UNIT WITHOUT FIRST
RECEIVING WRITTEN AUTHORIZATION AND SHIPPING INSTRUCTIONS FROM NILES.
If the above conditions are met, the purchaser's sole remedy shall be to return the product to
NILES, in which case NILES will repair or replace, at its sole option, the defective product
without charge for parts or labor. NILES will return a unit repaired or replaced under warranty
by shipping same by its usual shipping method from the factory (only) at its expense within the
United States of America. THERE ARE NO OTHER WARRANTIES, INCLUDING WITHOUT
LIMITATION, EITHER EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE, WITH RESPECT TO THE PRODUCT.
REPAIR OR REPLACEMENT AS PROVIDED UNDER THIS WARRANTY IS THE EXCLUSIVE
REMEDY OF THE CONSUMER/PURCHASER. NILES SHALL NOT BE RESPONSIBLE FOR
ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES EXCEPT TO THE EXTENT PROVIDED
(OR PROHIBITED) BY APPLICABLE LAW.
Some states do not allow the exclusion or limitation of incidental or consequential damages,
so the above limitation may not apply to you. This warranty gives you specific legal rights,
and you may also have other rights which vary from state to state.
