PLACING THE OS3 FOR THE BEST SOUND QUALITY
The OS3'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 environment 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.
