Positioning speakers
Speaker placement plays an important role in the reproduction of
Surround sound. The placement of the speakers varies depending
on the size of the room and the wall coverings used in the room.
The illustration shows an example of a layout for standard speaker
placement. Refer to this example when you position the speakers in
order to experience the best of Surround sound.
Standard speaker placement
For ideal Surround effects, all speakers should be installed. If a
center speaker or subwoofer is not connected, the sound from the
unused channel is properly distributed to the connected speakers in
order to produce the best Surround sound possible.
Front: The left, right, and center speakers should face the seated
listener and be placed at ear level. The center speaker produces a
richer sound image by enhancing the perception of the sound’s
source and movement.
Surround: Place the left and right Surround speakers 1 meter
(3 feet) above the listener’s ear level and facing toward the sides of
the room, making sure that the listener is within the speakers’ dis-
persion angle. These speakers produce the feel of a moving sound
while creating the sensation of being in the middle of the action.
Subwoofer: Install a subwoofer with a built-in power amplifier for
powerful bass sounds. The placement of the subwoofer does not
affect the final quality of the sound image too much, so you can
install it with the room layout in mind.
Refer to the speaker’s instruction manual for more details.
