Positioning Speakers - Onkyo DR-90 Instruction Manual

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 below 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 reproduce 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 reproduces 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' dispersion angle. These speakers
reproduce 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 wherever it is convenient.
Refer to the speakers' instruction manual for more details.
