INTRODU C TION The OS-20 marries unparalleled listening satisfaction with the freedom to listen to music anywhere! You can use them indoors and outdoors (even on a boat).
Rigid, Acoustically Inert Enclosure The cabinet of the OS-20 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-20 has hundreds of precisely sized perforations, creating an acoustically transparent grill.
P ARTS GUIDE 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.
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.
Placing the OS-20 for the Best Sound Quality The OS-20 ’s dispersion patter n is very broad. The speaker is very sensitive and will handle a lot of amplifier power.
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) .
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. 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.
INST ALLA TION 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.
3. Stand so you are the same distance from each speaker and listen to the rich- ness 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.
