speaker placement
Where you locate the speakers in the room plays a vital role in the sound quality you will enjoy. Since every
room is a little different, you should experiment with various locations to see which gives the best sound
in your particular application. Here are some general guidelines to help you select appropriate locations.
In general, your speakers will have the smoothest response and best imaging when located at least two
to four feet from the back and side walls in the listening room. Moving a speaker closer to one or more
of the boundaries will increase the bass output. In some rooms, the extra bass may sound good while in
others it may cause the bass to sound too strong.
Hard surfaces near a speaker can affect the distribution of high frequencies. Think of a hard wall as if it
is a mirror. Just as a mirror will reflect a nearby object so that you see a second "virtual" object, a hard
wall will reflect sound so that you hear a second "virtual" source of the sound. If the reflected sound is
strong enough it will confuse the imaging of the system. If the speakers are placed near side walls, try
toeing the speakers towards the center of the room. Drapes or cloth hangings on nearby walls will help
to cut down undesired reflections. Drapes are particularly helpful if the speaker is adjacent to windows or
glass doors.
center channel
The CM250LCR is normally positioned on its side, and functions as an accurate and exceptional center
channel speaker. The CM250LCR may be placed either above or below a video monitor when using a
direct view or rear projection set. The CM250LCR may also be used by positioning it vertically, which is
the recommended orientation for optimum horizontal dispersion. With front projection video monitors,
the center channel is commonly placed below the screen. Alternatively, by using an acoustically
transparent perforated screen it may be placed in a vertical orientation, directly behind the screen for
optimum imaging.
main speaker separation
A good rule of thumb is to start by arranging your preferred listening position and the left and right
speakers positions, such that they represent the points of an equilateral triangle. You should then
experiment by varying the separation and the horizontal angle of the speakers until you reach the sonic
sound stage that you prefer.
Although all of the CM series speakers are video shielded, placing them next to a TV monitor will not
typically give adequate separation. When possible, move the speakers a few feet away from either side of
the monitor. Also, when the center channel speaker is used, the left and right speakers should be located
so they are approximately the same distance from the listening position as the center channel. If they are
too far forward, you will lose integrity of the center image. If they are too far away, separation and image
width will suffer.
