ARCHITECTURALLY-FRIENDLY DESIGN Delivers stellar acoustical performance, yet tucks discreetly away into corners and under eaves. LOW-DIFFRACTION GRILLE AND FRONT BAFFLE Ensures that the sound waves emanating from the woofer and tweeter are not reflected by the surrounding parts of the loudspeaker for precise imaging and acoustical accuracy. RIGID, ACOUSTICALLY-INERT CABINET Prevents transmission of unwanted vibrations for clean and dynamic bass response. ALL-WEATHER VERSATILITY Reduces installat

RECOMMENDED AMPLIFIER POWER For optimum performance, we recommend amplifiers with the following power ratings: • For the OS 5.3Si loudspeaker, 5 to 100 W per channel • For the OS 6.3Si loudspeaker, 5 to 125 W per channel 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. W

PLACING THE LOUDSPEAKER FOR THE BEST SOUND QUALITY (CONTINUED) Make sure furniture or other objects will not block or reflect sound from the loudspeaker. You should have a direct line of sight with the front of the loudspeaker. 10' 1 0 ' Figure 5. Illustration depicts the optimum placement zone for a listening distance of 10 feet. You can control the loudspeaker’s bass output by placement. This is called the boundary effect. You will get more bass response by mounting the OS loudspeaker d

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

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. We recommend using attachment methods capable of supporting ten times the weight of the loudspeaker and bracket. If you are not

PAINTING THE LOUDSPEAKER 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 profess

Protect the front of the loudspeak er by inserting the supplied paint mask in place of the grille. PAINTING THE CABINET, BRACKET KNOBS, AND BRACKET 1. Apply tw o 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.

PAINTING THE GRILLE The grille is important to the sound of the 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. If you are using an appl

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 horizontally, so that the loudspeaker wire fits through the large, circular wire hole in the middle of the bracket. Align the bracket so it is square with the surroundings (use a level for accuracy). 3. Mark the locations of the three oval-shaped screw h

CONNECTING THE LOUDSPEAKER 1. For each loudspeaker wire, separate the two conductors on each end so that at least 2 inches are free. 2. Strip away 1/2 inch of insulation from each conductor on each end. 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 br acket to attach to a solid surface, slide the loudspeaker o

CHECKING LOUDSPEAKER PHASE Loudspeaker wire has two conductors. On both your receiver (or amplifier) and each set of loudspeaker binding posts, one conductor is attached to the negative (–) terminals, while the other is attached to the positive (+) terminals. Usually, the wire is marked for your convenience, but the marking can be done in the following different ways: • Stripe on one wire • Ribbed area you can feel on one conductor • Different colors of metal wire on each conductor • Fabri

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 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 loudspeake
