Page 8: 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 •... - Page 9 Figure 3 Figure 2 Wiring directly from a receiver Incorporating a volume control or amplifier Recommended Amplifier Power For optimum performance, we recommend an amplifier with a power rating of: five (5) to one hundred (100) watts per channel for the 0S 5.5 loudspeaker; five (5) to one hundred twenty five (125) watts per channel for the OS 6.5 loudspeaker;...
- Page 10 When using more than one pair, it is usually best to alternate a left channel and then a right channel, so that you have the best possible stereo coverage possible. The position of the loudspeakers and their surroundings play a very important role in how a stereo image is created.
- Page 11 If possible, mount the loudspeakers between eight and twelve feet high. The less the downward angle of the loudspeaker, the further the sound will carry. If the sound is carrying into areas where you do not want sound, try pointing the loudspeakers more downward, this will reduce the amount of sound further away from the loudspeaker.
- Page 12 Nail Mounting Figure 7 The OS loudspeaker can be mounted three ways. 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).

Page 13: Painting Os Series Loudspeakers
PAINTING THE LOUDSPEAKER The enclosure, the brackets, and the grilles of the 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. - Page 14 2. Wipe off the 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.
- Page 15 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 After the grille dries, carefully fit the grille into its recess so that it is barely 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. - Page 17 Attaching the foot (if using the loudspeaker in a free standing mode) 1. Loosen the bracket knobs and remove the bracket from the loudspeaker. 2. Tighten the top knob so it does not vibrate. 3. Remove the bottom knob by unscrewing it from the cabinet. 4.
- Page 18 5. Connect one stripped wire end to the black and one to the red terminal. Pay attention to the markings on the wire. Each loudspeaker wire 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.

Page 19: Operation
OPERATION 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 loudspeakers. It is possible to turn the volume so high that the amplifier runs out of power. -
