INTRODUCTION

Niles once again raises the bar. With our first OS Indoor/Outdoor models we
revealed a radical new understanding of loudspeaker capabilities. Niles original
OS Indoor/Outdoor loudspeakers are constantly praised for their ability to deliver
exemplary reliability and outstanding sound quality. These attributes have made
Niles OS Indoor/Outdoor loudspeakers the best selling loudspeakers in their class.

The goal of our new OS Indoor/Outdoor line-up is to raise this bar with refined
appearance and superior sonic performance. Once again establishing a
benchmark by which all others are judged. The new Niles OS Indoor/Outdoor
loudspeakers owe much of their performance and sound quality advantage to
design elements pioneered in the award-winning Niles DS Directed Soundfield™
loudspeakers. Their engineering advances come from our integrated approach to
driver and cabinet design. By integrating the woofer basket into the baffle of the
cabinet we are able to increase the woofer cone-area to cabinet-width ratio. Thus
enabling OS Indoor/Outdoor loudspeakers to provide levels of bass performance
that substantially exceed their physical size. However, deeper and more powerful
bass isn’t the only refinement in the new OS Indoor/Outdoor line-up. A new and
modern style enables OS Indoor/Outdoor loudspeakers to blend seamlessly with
the architectural elements both indoors and out. After the installation is complete,
you will be astonished by the experience of hearing such clean and powerful
sound coming from such an elegant appearing loudspeaker.

INSTALLATION CONSIDERATIONS

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 loudspeaker connects to your receiver or amplifier using 2x2-conductor
loudspeaker 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 on the OS loudspeaker will accommodate up to 12 gauge
wire directly. Larger sizes can be accommodated using spade, banana, or pin
connectors.

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.

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.
