About Speaker Installation
I
Surround back speakers.
Sound positioning directly to the rear can be achieved easily by adding
a surround back speaker to a 5.1-channel system.
In addition. the acoustic image extending between the sides and
the rear is narrowed. thus greatly improving the expression of the
surround signals for sounds moving from the sides to the back and
from the front to the point directly behind the listening position.

conventional 2- to 5.1-channel sources can also be enhanced.

Setting 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.
