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.

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.
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.

Incorporating a Volume Control
It’s possible to control the volume of the sound at the loudspeaker location. Plan to
wire the system so that each loudspeaker 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 control and
then from the volume control to the loudspeaker (See Figure 3).
Recommended Amplifier Power
For the OS 5.3Si loudspeaker, we recommend an amplifier with a power rating of
five (5) to one hundred (100) watts per channel for optimum performance. For the
OS 6.3Si loudspeaker, we recommend an amplifier with a power rating of five
(5) to one hundred twenty five (125) watts per channel for optimum performance.
Ironically, most speakers are not damaged by large amplifiers but by small
amplifiers. If you are playing at high volume, 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.

Placing the OS Loudspeaker for the Best Sound Quality
Traditionally, when using a pair of stereo loudspeakers, the listener will be
positioned directly between the left and right loudspeakers to achieve optimum
stereo sound. However, in some applications this is not possible, especially when
a large area of coverage is required. It was for these types of applications that the
OS “Si” loudspeaker was created. With its ultra wide dispersion pattern, a single
OS “Si” loudspeaker is able to project quality stereo sound over a larger area. No
matter where you are—You are always in the sweet spot. (See Figure 4).
Make sure that you are not blocking or reflecting the sound off of furniture or other
objects. You should have a direct line of sight with the front of the loudspeaker.
