Using two speakers results in a smoother blend with the sound of the surround channels and better sound positioning of the surround back channel when listening from a position other than the center.
2Placement of the surround left and right
channels when using surround back speakers
Using surround back speakers greatly improves the positioning of the sound at the rear. Because of this, the surround left and right channels play an important role in achieving a smooth transition of the acoustic image from the front to the back. As shown in the diagram above, in a movie theater the surround signals are also produced from diagonally in front of the listeners, creating an acoustic image as if the sound were floating in space. To achieve these effects, we recommend placing the speakers for the surround left and right channels slightly more towards the front than with conventional surround systems. Doing so sometimes increases the surround effect when playing conventional

•Set the front speakers with their front surfaces as flush with the TV or monitor screen as possible. Set the center speaker between the front left and right speakers and no further from the listening position than the front speakers.
•Consult the owner’s manual for your subwoofer for advice on placing the subwoofer within the listening room.
•If the surround speakers are
•When using two surround back speakers, place them at the back facing the front at a narrower distance than the front left and right speakers. When using one surround back speaker, place it at the rear center facing the front at a slightly higher position 0 to 0.7 feet than the surround speakers.
•We recommend installing the surround back speaker(s) at a slightly downward facing angle. This effectively prevents the surround back channel signals from reflecting off the monitor or screen at the front center, resulting in interference and making the sense of movement from the front to the back less sharp.

wSetting for primarily watching movies using diffusion type speakers for the surround
speakers
For the greatest sense of surround sound envelopment, diffuse radiation speakers such as bipolar types, or dipolar types, provide a wider dispersion than is possible to obtain from a direct radiating speaker (monopolar). Place these speakers at either side of the prime listening position, mounted above ear level.

[ As seen from the side ]
•Set the front speakers, center speaker and subwoofer in the same positions as in example (1).
•It is best to place the surround speakers directly at the side or slightly to the front of the viewing position, and 2 to 3 feet above the ears.
•Same as surround back speaker installation method (1). Using dipolar speakers for the surround back speakers as well is more effective.
•The signals from the surround channels reflect off the walls as shown in the diagram above, creating an enveloping and realistic surround sound presentation.
