Before you begin to connect cables, it is important to place your
speakers in their correct locations in the room.
Optimally, the speakers should be placed in a circle with the listening
position at its center. The distance from the listening position to the
video display forms the radius of the circle. See Figure 15.
The speakers should be angled so that they directly face the
listening position.
The center speaker is placed either on top of, below or mounted on
the wall above or below the video display screen.
The front left and right speakers are placed along the circle, about
30 degrees from the center speaker and angled toward the listener.
It is best to place the front left/right and center speakers as close to
the same height as possible, preferably at about the same height as the
listener’s ears. In any event the center speaker should be no more than
two feet above or below the left/right speakers.
The side surround speakers should be placed 110 degrees from the
center speaker, that is, slightly behind and angled toward the listener.
If this isn’t feasible, place them behind the listener, with each surround
speaker facing the opposite-side front speaker. The surround speakers
may be placed a little higher than the listener’s ears.
The subwoofer’s location is less critical, since low-frequency sounds are
omnidirectional. Placing the subwoofer close to a wall or in a corner will
reinforce the low frequencies, and may create a “boomy” sound. You
may wish to experiment over time by placing the subwoofer where the
listener normally sits and then walking around the room until the low
frequencies sound best. Place the subwoofer in that spot.
NOTE: Your receiver will sound its best when the same model
loudspeaker is used for all positions (other than the subwoofer).
If that isn’t possible, try to use speakers made by the same
manufacturer.
