INSTALLATION CONSIDERATIONS DS00427ACN_OS_3Si.qxp 12/20/04 5:51 PM Page 9 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

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

PAINTING THE LOUDSPEAKER DS00427ACN_OS_3Si.qxp 12/20/04 5:52 PM Page 13 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

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 corr

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 ma

OPERATION DS00427ACN_OS_3Si.qxp 12/20/04 5:52 PM Page 17 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 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 an
