INTRODUCTION

The RS5 series of weatherproof rock loudspeakers are designed to provide

unparalleled listening satisfaction and GeoRealistic™ styling. The extraordinary

sonic performance of the RS5 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 RS5 series loudspeaker is a two-way loudspeaker in an acoustic suspension

enclosure. 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.

INTRODUCTION

FEATURES & BENEFITS

GeoRealistic™ Styling

Traditionally, rock speakers have looked like ornaments and not like rocks. Each

RS5 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 RS5 to blend in with other landscaping and disappear. All that will be

noticed is the great sound not the loudspeaker.

Weather Proof 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 RS5 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 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 RS5 has proven

itself to withstand the harshest conditions Mother Nature can throw at it.

5-1/4” Talc Filled Polypropylene Woofer

The unusually stiff talc 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 5-1/4” woofer can create outstanding bass output. In the

end, the woofer design provides deep rich bass and outstanding weather resistance

capabilities.

1/2” Kaladex™ Tweeter

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

RS5’s 1/2” Kaladex™ tweeter employs DuPont’s latest material technology to

produce a dome tweeter with exceptional frequency response and low distortion.

The result is a transparent clear, sweet, natural sounding tweeter, which still

maintains its extended frequency response and is completely weatherproof.

Tweeter Placement Improves Coverage and Dispersion

The tweeter is angled twenty degrees up from the woofer. This means that it is

“aimed” at the listener and not at the ground. This improves the high frequency

coverage of the loudspeaker and ensures that all the benefits of the tweeter are

heard and not lost in the surroundings.

FEATURES & BENEFITS

Precision Crossover

A customized electronic dividing network inside the cabinet precisely distributes

the music to the woofer and the tweeter. The three-pole two-way design of the

RS5 crossover provides excellent stereo imaging, low distortion and superior sonic

performance.

ConeForward™ Design

Most competitive 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 of the

loudspeaker 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 not the cabinet ringing.

Low Diffraction Microperf™ Aluminum Grilles

The aluminum Microperf™ grille on the RS5 has 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 Cable 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 a three-foot connection cable 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

provided even greater security, if you require it.

FEATURES & BENEFITS

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 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 RS5 loudspeaker can be installed directly on the ground, in a flowerbed, on a

wood deck or on a concrete/stone patio. There are two considerations for placing

the loudspeaker, ease of running the cable to the loudspeaker and coverage of the

loudspeaker. The RS5 loudspeaker will cover an area of a circle with a 16-foot

diameter, in front of the speakers.

If you are using stereo outputs from the amplifier, alternate the speakers to provide

the best imaging. You should place speakers less than 8 feet from the sides of the

listening area and 12 feet from each other. The row spacing should not be greater

than 20 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.

INSTALLATION CONSIDERATIONS

Figure 1 Stereo Coverage 4 speakers

Figure 1 shows how this would work for a square area of 28 feet by 20 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 in the diagram.

Figure 2 shows the same area as Figure 1, however the number of speakers has

increased by 2. You can see a greater area of stereo coverage and this would

also 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.

Achieving high quality stereo coverage in a large area is costly. You need to use

more speakers and more amplifier power or separate amplifiers. If a large area

needs to be covered, consider using a summed stereo or mono signal for each

speaker. If summing the stereo inputs into the amplifier or setting the amplifier to

play in mono is acceptable, the loudspeakers can be spaced 8 feet from the sides

and 16 feet from each other. The row spacing between speakers should be less than

30 feet. This will increase the area your loudspeakers will cover.

INSTALLATION CONSIDERATIONS

Table 1 Spacing Rules

Figure 2 Stereo Coverage 6 speakers

Sources Spacing Spacing Between Spacing

from Sides Speakers within a row Between Rows

Stereo 8 ft 12 ft 20 ft

2.4m 3.7m 6.1m

Mono 8 ft 16 ft 30 ft

2.4m 4.9m 9.1m

Note: These are maximun recomended distances, sound quality is improved if

you use smaller spacings.

Figure 3 shows the difference in coverage area using the spacing rules for mono

signals. Using the same four speakers as we did in Figure 1, we can increase our

coverage area from 560 square feet (52 sq. meters) to 960 square feet (88.3 sq.

meters), simply by using a mono source.

The trade off in sound quality between mono sources and stereo sources is sonic

imaging. If you are concerned with keeping the instruments and vocals sonically

separated, then stereo setup must be used.

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 and void

the warranty.

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 (2) RS5

loudspeakers can be safely attached to a typical amplifier channel, if that

amplifier is rated to drive 4 ohms. 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.

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

4 speakers and a master volume control is shown in Figure 4. 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 Figure 5. 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.

INSTALLATION CONSIDERATIONS

Figure 4 One Zone Volume Control Wiring

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 one 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 RS5 speakers on one amplifier channel, an

amplifier rated to drive a 4-ohm load of thirty watts to two hundred watts, is

recommended. If you use two RS5’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.
