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 harmonizing unique and proprietary technology with the most advanced manufacturing methods and materials available. INTRODUCTION INTRODUCTION The OS-10 is a two-way speaker in an acoustic suspension enclosure. The cabinet is shaped to fit neatly into corners or eaves.
FEATURES & BENEFITS 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.
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 optimized for the best sound. Sound waves emanating from the woofer and the tweeter are not reflected by the surrounding parts of the speaker.
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.

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-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.
INSTALLATION CONSIDERATIONS Figure 2 Wiring directly from a receiver or amplifier Figure 3 Incorporating a volume control 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.
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.
You can control the speakers bass output by placement. This is called the boundary effect. You will get more bass response by mounting the OS-10 directly to a wall or other flat surface (any boundary close to the speaker will reinforce the bass frequencies). You can increase the bass output even more by mounting the OS-10 in a corner or under an eave (See Figure 5) This type of placement gives the speaker two boundaries, both reinforcing the bass sounds.
INSTALLATION CONSIDERATIONS 1. If the speaker 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) of the bracket (See Figure 7). Nail Mounting Screw Mounting OmniMount or Custom Bracket Mounting Figure 7 The OS-10 can be mounted three ways. 2.
The enclosure, the brackets, and the grills of the OS-10 can all be painted to match the surroundings. Because we want you to preserve the acoustic qualities of the grill, please paint the grill according to the grill 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.
PAINTING THE OS-10 2. Wipe off the other sides of the cabinet, the bracket, bracket knobs, and grill with a damp cloth. Do not touch or rub the speakers 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 speakers by inserting the supplied paint masks in place of the grills.
Replacing the Grill Carefully fit the grill into its recess so that it is barely in place. Starting with one corner, go around the speaker, pushing the grill in a little bit each time. You should be gentle, the aluminum grill can be easily bent out of shape. You will feel a positive “snap” when it is fully in place. PAINTING THE OS-10 If you are using an applicator or brush and a can of paint, thin the paint first. Thick paint will tend to clog the grill holes.
INSTALLATION INSTALLATION Mounting the Bracket 1. Remove the bracket knobs and the bracket from the speaker. 2. Hold the bracket up to the mounting surface. The speaker can be mounted either horizontally or vertically. Hold the bracket so that the speaker wire fits through the large, circular wire hole in 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.
1. Separate the two conductors of the speaker 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 speaker wire. INSTALLATION Connecting the Speaker 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. Use the bracket knobs to attach the speaker to the bracket.
INSTALLATION 3. Stand so you are the same distance from each speaker and listen to the richness of the bass and the loudness of the sound. 4. Turn off the amplifier and reverse the connections on one speaker only. 5. Repeat the listening test with the same setting of the volume control. When the sound has a richer bass and is slightly louder the speakers are working together or “in-phase”. Final Adjustments 1.
Listening at Higher Volumes OPERATION OPERATION 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 speaker. 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.
