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.

Movement of acoustic image from 
SR to SB to SL
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 2 speakers.
When using dipolar speakers in particular, be sure to use 2 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.
Examples of speaker layouts
Below we introduce examples of speaker layouts. Refer to these to 
arrange your speakers according to  their type and  how you want to 
use them.

About Speaker Installation
w 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.
