Placement of the speakers affects how well the AV surround system
recreates the sound field 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, and with left and right
speakers placed so they each form a 30 degree angle from the center line.
Left and right surround speakers are placed 110 degrees from the center line.
Left and right rear speakers in a 7.1 system are typically at 140 degrees. If
a single rear speaker is used in a 6.1 system, it should be centered 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. The best
recreation of the desired sound field is achieved by recreating this speaker
pattern as closely as your room and furnishings allow.
Don’t be too concerned if your situation and listening environment dictate
somewhat different speaker positions. Most rooms do not allow ideal
placement. Place your speakers as close to these guidelines as practical and
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”.
• 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.
