About the speakers
Surround back speakers
Sound position 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.

In addition to sources recorded in 6.1-channels, the surround effect of
conventional 2- to 5.1-channel sources can also be enhanced.
¢ Number of surround back speakers
We recommend using two speakers.
When using dipolar speakers in particular, be sure to use two speakers.
¢ Placement of the surround left and right channels
when using surround back speakers
We recommend installing the speakers for the surround "L" and "R"
channels a bit forward.
