INSTALLATION CONSIDERATIONS

Placing the OS-20 for the Best Sound Quality

The OS-20’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. A good rule of thumb is a pair of speakers for every 200 to 400 square feet of listening area. Your local Niles dealer is a good source for advice on speaker placement for your particular installation.

When using more than one pair, it is usually best to alternate a left channel and then a right channel, so that you never have a "left next to a left".

The position of the speakers and the surroundings around them play a very important role in how a stereo image is created. You should experiment to find the very best position for your speakers. Here are some guidelines to make the process quick and easy.

avoids a "hole-in-the-middle" effect). For example; if you are ten feet back from

 

the wall, the speakers should be between five and ten feet apart (See Figure 4).

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-20directly 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-20in a corner or under an eave (See Figure 5) This type of placement gives the speaker two boundaries, both reinforcing the bass sounds. Of course, if you wish to hear less bass, try moving the speaker away from the boundary (See Figure 6).
