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.
2 Number of surround back speakers
We recommend using 2 speakers.
When using dipolar speakers in particular, be sure to use 2
speakers.
2 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.
