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.

You can control the loudspeakers bass output by placement. This is called the
boundary effect. You will get more bass response by mounting the OS loudspeaker
directly to a wall or other flat surface (any boundary close to the loudspeaker will
reinforce the bass frequencies). You can increase the bass output even more by
mounting the OS loudspeaker in a corner or under an eave (See Figure 5) This type
of placement gives the loudspeaker two boundaries, both reinforcing the bass
sounds. Of course, if you wish to hear less bass, try moving the loudspeaker away
from the boundary (See Figure 6).
Mounting Methods
The OS loudspeaker should be mounted horizontally. The bracket knobs will keep
the loudspeaker angled correctly in any position once they are tightened. You can
choose from three mounting methods to attach the OS loudspeaker to the wall,
ceiling, or other mounting surface.
1. If the loudspeaker is never going to be exposed to sudden accidental impacts,
wind, waves or earthquakes you can simply hang it on a nail using the nail
hole(s) on the bracket (See Figure 7).
2. The safest and most secure way to mount the loudspeaker is by screwing it to the
mounting surface using your own hardware (suitable for the surface you are
mounting to) and the bracket supplied with the loudspeaker (See Figure 7).

3. There is a threaded brass insert (1/4" – 20) on the back of the OS loudspeaker for
attaching a custom bracket (See Figure 7). This allows you to position the
loudspeaker at unusual angles or varying distances from the mounting surface.
Safety First!
Be careful to use hardware that is designed for the surface you are mounting to. The
OS 5.3Si loudspeaker (including bracket) weighs 9 pounds. The OS 6.3Si
loudspeaker (including bracket) weighs 11 pounds. If you are not sure of a safe
way to mount the loudspeakers, consult a professional installer or a building
contractor.
You will maximize the useful life of the loudspeaker, by placing the loudspeaker so
that it receives less exposure to the elements. Look for the best overall compromise
between sound quality, convenience, and exposure. Do not compromise safety.

The enclosure, the brackets, and the grilles of the OS loudspeaker can all be
painted to match the surroundings. Because we want you to preserve the acoustic
qualities of the grille, please paint the grille according to the grille painting
instructions. Make sure you pick a paint that is appropriate for the mounting
location. There are interior and exterior varieties, and even paint for marine uses. If
you are not sure what paint to use, consult a paint store professional or a painter.
Tools Required
• A spray can of primer paint
• The correct paint for the environment/use (oil or water based paint is fine)
• A paint brush or applicator if the paint is not in a spray can.
• A paper clip or an awl (for removing the grille)
• Masking tape
• 2 paint masks (supplied)
• A damp cloth and a dry cloth
Preparing to Paint
1. Separate the parts of the speaker.You should remove the brackets and the bracket
knobs. Remove the grille by hooking it with a bent paper clip or the tip of an awl
and pulling it away from the cabinet (See Figure 8).

2. Wipe off the other sides of the cabinet, the bracket, bracket knobs, and grille with
a damp cloth. Do not touch or rub the loudspeakers on the front baffle. Make
sure everything is dry before masking.
3. Mask off the binding posts and the brass threaded inserts on the back panel with
masking tape.
4. Mask off the threaded inserts on the top and bottom with masking tape.
5. Protect the front of the loudspeaker by inserting the supplied paint mask in place
of the grille.
Painting the Cabinet, Bracket Knobs and Bracket
1. Apply two thin coats of a sandable spray primer to the cabinet and knobs. The
bracket doesn't require a coat of primer.
2. Allow the primer to dry completely.
3. Apply the finish color.
4. Allow the paint to dry completely.
5. Carefully remove the masking material.
6. Do not reattach the loudspeaker to the bracket until the bracket is mounted. Try
to keep all handling of the freshly painted parts to a minimum.
Painting the Grille
The grille is important to the sound of the OS loudspeaker. Do not fill the holes of
the grille with paint. The grille is constructed of aluminum with a perfectly even
powder coat overall. This powder coat is an ideal primer.
If you are using a spray paint, use two thin coats without any primer. If you are using
a compressor and a spray gun, use the finest, most diffuse setting. Practice on paper
if you are not experienced in painting with spray paint.

PAINTING THE LOUDSPEAKER
If you are using an applicator or brush and a can of paint, thin the paint first. Thick
paint will tend to clog the grille holes. To ensure a uniform appearance, paint the
front and back of the grille.
Replacing the Grille
Carefully fit the grille into its recess so that it is barely in place. Starting with one
corner, go around the speaker, pushing the grille in a little bit each time. You should
be gentle, the aluminum grille can be bent easily out of shape. You will feel a
positive “snap” when it is in place.

INSTALLATION
Mounting the Bracket (if attaching the loudspeaker to a wall, ceiling, beam or
other solid structure)
1. Loosen the bracket knobs and remove the bracket from the loudspeaker.
2. Hold the bracket up to the mounting surface. The loudspeaker can be mounted
either horizontally or vertically. Hold the bracket so that the loudspeaker wire fits
through the large, circular wire hole in the center of the bracket. Align the
bracket to be square with the surroundings (use a level for accuracy).
3. Mark the locations of the three oval-shaped screw holes (See Figure 9). Be sure
to use all of the holes.
4. Drill pilot holes into the mounting surface.
5. Pull the loudspeaker wire through the wire hole in the center of the mounting
bracket. Align the bracket so that the holes all line up.
6. Use your hardware to attach the bracket to the mounting surface.

Connecting the Loudspeaker
1. Separate the two conductors of each loudspeaker wire so that at least two inches
of each conductor are free.
2. Strip one half inch of insulation from the end of each conductor of the
loudspeaker wires.
3. If you have any connectors (gold pins or bananas) which you prefer to use, affix
them to the stripped wire ends now. Only gold plated connectors should be used
outside as they will not tarnish or corrode.
4. If using the bracket to attach to a solid surface, slide the loudspeaker onto the
bracket. Do not tighten the knobs completely. Angle the loudspeaker so that the
rear terminals are accessible.
5. Connect one stripped wire end to the black and one to the red terminal (repeat
this for the other channel). Pay attention to the markings on the wire. Each
channel must be connected to the amplifier in the same way.
6. If required, attach the safety cable to the loudspeaker enclosure. See Safety First
section for details.
7. Verify that the loudspeaker is in-phase as described in the Loudspeaker Phase
section.
8. Angle the loudspeaker for the best sound possible.

9. Tighten the bracket knobs using only your hands. Use of any power tools may
over-tighten the knob, and strip the threads of the insert.
10. Check that the entire installation is safe and secure.
Loudspeaker Phase
Loudspeaker wire has two conductors. One conductor is attached to the negative
(-) terminals and one conductor is attached to the positive (+) terminals of both your
loudspeaker and your amplifier. Usually, the wire is marked for your convenience.
There are different ways to mark the wire; a stripe on one wire, a ribbed area of one
conductor you can only feel, different colors of metal wire on each conductor, or
there might be a fabric strand or string wound into one of the conductors. Of
course, there are some wires which appear completely identical. Be careful to
avoid mistakes. If you do, the woofer of the OS loudspeaker will not be playing
loudly. If you do not hear any or very little “bass” coming from the loudspeaker try
this simple test:
1. Play some music with the amplifier or radio set to Mono.
2. Listen to the richness of the bass and the loudness of the sound.
3. Turn off the amplifier and reverse the connections on one loudspeaker terminal
only.
4. Repeat the listening test with the same setting of the volume control.
5. If the sound is louder in step 4 then step 2 leave the terminals connected the way
they are. If not, put the connections back the way they were in step 1.
DS00427ACN_OS_3Si.qxp 12/20/04 5:52 PM Page 16

18
Listening at Higher Volumes
Outdoors there are no walls to reflect and contain the sound. It requires more
power to achieve a reasonable volume of sound outside than it does when you
are indoors. You also frequently find yourself very far from the loudspeaker. It is
possible to turn the volume so high that the amplifier runs out of power. This creates
“clipping” distortion.
Clipping distortion makes treble sound very harsh and unmusical. When you
hear harsh sounding treble from any good loudspeaker indoors or outdoors, turn
the volume down immediately! Those harsh sounds are masking some much
more powerful ultra-high-frequency sound spikes which will quickly damage any
fine loudspeaker.
Cleaning
You can clean the OS loudspeaker with a dampened soft cloth or paper towel. If
the loudspeaker is mounted high up on a wall or ceiling, use a broom to gently
brush it off. Hosing off the loudspeaker is not recommended, as the tweeter is a
precise mechanism which might be damaged by a high pressure stream of water.
