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

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.

installation Considerations

tools and Materials required

• A wire stripper

• 1/2” PVC conduit (optional)

• PVC conduit glue and cleaner (optional)

• PVC cutting tool (optional)

• Trench digger or shovel

• Tube of silicone sealant (optional)

• Cable (length and type determined by installation site –

see “Choosing the Speaker Cable”)

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.

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.

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.

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.

Choosing the speaker Cable

In order to choose the proper speaker cable, please follow these steps:

• Unless you are using an impedance matching system, use care when

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/

receiver prior to making any connections or running any wires.

• You will need 2-conductor speaker cable that clearly identies 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. 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.

• 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 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.
