SPEAKER PLACEMENT
The proper placement of speakers affects how well the AV
surround system recreates the soundfield intended by the
recording engineer. Current recording practice typically
assumes a speaker array with a center channel speaker
directly in front of the central viewing position. Left and right
speakers are placed so they each form a 30 degree angle
from the centerline. Left and right surround speakers should
be 110 degrees from the centerline. Left and right rear
speakers in a 7.1 system should be at 140 degrees. If a sin-
gle rear speaker is used in a 6.1 system, it should be cen-
tered on the rear wall. Front speakers should be as close to
the height of the TV monitor as practical. Surround and rear
speakers should be slightly higher. Recreate this speaker
pattern as closely as your room and furnishings allow.
Don’t be too concerned if your situation and listening envi-
ronment dictate the speakers’ position. Most rooms do not
allow ideal placement. Place your speakers as close to
these guidelines as practical. The speakers will still provide
convincing, lifelike sound.
Your surround processor has a variety of adjustments to
optimize the sound based on the speakers’ capabilities and
placement. These adjustments vary by processor, so refer
to your processor’s manual for instructions specific to your
equipment. Set your main, center, and surround settings to
“SMALL”, with subwoofer “ON”. If your processor allows you
to adjust the crossover frequency, set it as close to 100Hz
as possible.
• Avoid placing front left and right speakers very close to a
side wall (within 12-14 inches). The reflected sound from the
wall degrades the sound coming directly from the speaker.
