About Speaker Installation

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.
Change of positioning and acoustic image
with 5.1-channel systems
Movement of acoustic image from SR to SL
Change of positioning and acoustic image
with 6.1-channel systems
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

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.
