INTRODUCTION

The OS-10 marries unparalleled listening satisfaction with the freedom to listen

to music anywhere! You can use them indoors and outdoors (even on a boat).

The extraordinary sonic performance of the OS-10 was achieved by harmoniz-

ing unique and proprietary technology with the most advanced manufacturing

methods and materials available.

The OS-10 is a two-way speaker in an acoustic suspension enclosure. The cabi-

net is shaped to fit neatly into corners or eaves. It is supplied with a swiveling

mounting bracket for easy installation anywhere. In addition, our engineers

constructed the OS-10's to withstand the stresses and strains of the world out-

side! For the first time, serious listeners can enjoy a concert on the green in

their own back yard.

INTRODUCTION

FEATURES & BENEFITS

Precision Crossover

An electronic dividing network inside the cabinet precisely distributes the

music to the woofer and the tweeter. The two-way design of the OS-10’s

crossover provides excellent stereo imaging and low distortion.

ElastoDynamic™Hybrid Dome Tweeter

In the past, every weather-resistant speaker has disappointed listeners with a

fatiguing and harsh treble sound caused by tweeter ringing. In the course of

developing our weather-resistant tweeter, we determined that tweeter ringing

can be damped out by a microscopically thin elastomeric coating on a natural

fiber dome substrate. The result is a transparently clear, sweet, natural sounding

tweeter which still maintains extended frequency response.

Long Throw Polypropylene Woofer

The unusually stiff and light polypropylene cone, the butyl rubber surround, the

substantial magnet, and the rigid steel basket are all optimized for large excur-

sions of the woofer. In this way, the five and a quarter inch cone can create the

same deep bass output of a much larger speaker moving small distances in and

out. The end result is rich satisfying bass from a compact, weather-resistant

loudspeaker.

Eight Ohm Impedance

The OS-10's are designed to be part of a multi-room audio system. The OS-10's

eight ohm impedance makes them compatible with virtually any amplifier. In

addition, this permits multiple pairs of OS-10’sto be wired to a single amplifier

with a Niles speaker selector.

FEATURES & BENEFITS

Rigid, Acoustically Inert Enclosure

The cabinet of the OS-10 is composed of mineral filled polypropylene. This

material is extremely non-resonant. All you hear is the music.

Low Diffraction Grill and Front Baffle

The grill of the OS-10 has hundreds of precisely sized perforations, creating an

acoustically transparent grill. The front baffle is gently curved in a radius opti-

mized for the best sound. Sound waves emanating from the woofer and the

tweeter are not reflected by the surrounding parts of the speaker.

Tapering Shape

The cabinet of the OS-10 is shaped so that the speaker will tuck discretely away

into corners or under eaves.

Swiveling Bracket

The U-shaped bracket and bracket knobs allow the OS-10 to be pointed at the

optimum listening position and locked into place quickly and easily.

Easy Three-Way Mounting System

1. The OS-10 can be hung from a nail using the nail hole on the bracket.

2. The bracket can be screwed into the mounting surface using your hardware.

3. The OS-10 is equipped with 1/4-20 threaded inserts for OmniMount®or

custom brackets.

Stable Shelf Placement

The rubber inserts on the bracket knobs serve as one of the speaker's feet when

the OS-10 is placed directly on a shelf or desktop without the bracket. In addi-

tion, two feet are molded into the base of the cabinet to give added stability.

FEATURES & BENEFITS

Premium Gold-Plated Five-Way Binding Posts

Gold plating gives you a corrosion-free high quality speaker wire connection.

The connectors' five-way design allows you to use any of the most popular wire

terminating methods.

Easy Finger-Sized Access

The binding posts are mounted upside down in a molded recess on the back of

the OS-10. This prevents water from pooling at the connection. The recess is

large enough to fit your fingers, so you can easily loosen or tighten the speaker

connections.

Weather-Resistant Construction

The hardware is made of stainless steel or brass, and the binding posts are plated

with gold. The bracket and grill are made of aluminum (oxidation is self-limiting

with aluminum) and it is powder coated (powder-coating gives absolutely even

coverage everywhere) for the ultimate rust-proof construction. The enclosure itself

is shatterproof. The OS-10’scomponents are weather-resistant, UV-resistant,

salt-water corrosion-resistant, and immune to damage from temperature extremes

(-50 to over 200 degrees Fahrenheit).

INSTALLATION CONSIDERATIONS

Tools and Materials Required

•A wire stripper

•A pencil

•A level (optional)

•Three screws or bolts suitable for the mounting surface

•The proper screwdriver for your mounting hardware

•A drill bit of the right size and type

•An electric drill

Wiring

The OS-10 connects to your receiver or amplifier using 2-conductor speaker

wire (See Figure 2). For most applications, we recommend using 16 or 18

gauge wire. For wiring runs longer than 80 feet, we recommend 14 gauge wire.

The binding posts of the OS-10 will accommodate up to 12 gauge wire direct-

ly. Larger sizes can be accommodated using spade, banana, or pin connectors.

When you run wire inside walls, outdoors or in marine installations, special

jacketing or conduit is required for a trouble-free installation and conformation

to the local and national building codes. If you are not sure of the correct wire

jacket or type of conduit to use, consult a professional audio/video installer,

building contractor, or the local building and inspection department.

TECH TIP

Wire size is expressed by its AWG (American Wire

Gauge) number. The lower the number, the larger

the wire, i.e. twelve AWG is physically larger than

fourteen AWG.

INSTALLATION CONSIDERATIONS

Incorporating a Volume Control

It’s possible to control the volume of the sound at the speaker location. Plan to

wire the system so that each pair of speakers has it’s own volume control. Niles

makes a wide range of indoor and outdoor volume controls. Consult your local

Niles dealer for more information. Volume controls are connected in line with

the speaker, so you must connect the wire from the amplifier to the volume con-

trol and then from the volume control to the speaker (See Figure 3).

Recommended Amplifier Power

We recommend an amplifier with a power rating of five to one hundred watts

per channel for optimum performance. Ironically, most speakers are not dam-

aged by large amplifiers but by small amplifiers. If you are playing at high vol-

ume, 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 distorting. See the section "Operation"for

more information about clipping distortion.

INSTALLATION CONSIDERATIONS

Placing the OS-10 for the Best Sound Quality

The OS-10’s dispersion pattern is very broad. The speaker is very sensitive and

will handle a lot of amplifier power. This allows good sound quality over an

extremely large listening area. However, if a single pair is positioned to provide

coverage of a very large room or patio, you will have “hot spots”of loud sound

when you are near the speakers. The best way to avoid hot spots for a large

space is to use several pairs. A good rule of thumb is a pair of speakers for

every 200 to 400 square feet of listening area. Your local Niles dealer is a good

source for advice on speaker placement for your particular installation.

When using more than one pair, it is usually best to alternate a left channel and

then a right channel, so that you never have a "left next to a left".

The position of the speakers and the surroundings around them play a very

important role in how a stereo image is created. You should experiment to find

the very best position for your speakers. Here are some guidelines to make the

process quick and easy.
