Speaker setting examples
Here we describe a number of speaker settings for different purposes. Use these examples as guides to set up
your system according to the type of speakers used and the main usage purpose.
1. DTS-ES compatible system (using surround back speakers)
(1) Basic setting for primarily watching movies
This is recommended when mainly playing movies and using regular single way or 2-way speakers for
the surround speakers.
• Set the front speakers with their front

surfaces as flush with the TV or monitor
screen as possible. Set the center speaker
between the front left and right speakers
Monitor
and no further from the listening position
Subwoofer
than the front speakers.
60°
• Consult the owner's manual for your
Surround
subwoofer for advice on placing the
speakers
subwoofer within the listening room.
• If the surround speakers are direct-radiating (monopolar) then place them
slightly behind and at an angle to the listening position and parallel to the
60°
walls at a position 60 to 90 centimeters (2 to 3 feet) above ear level at the
prime listening position.
Surround back speakers
• When using two surround back speakers, place them at the back facing the
As seen from above
front at a narrower distance than the front left and right speakers. When
using one surround back speaker, place it at the rear center facing the front
at a slightly higher position (0 to 20 cm) than the surround speakers.
• We recommend installing the surround back speaker(s) at a slightly
downward facing angle. This effectively prevents the surround back channel
signals from reflecting off the monitor or screen at the front center, resulting
in interference and making the sense of movement from the front to the
back less sharp.
(2) 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.
Path of the surround sound from the
speakers to the listening position
• Set the front speakers, center speaker
and subwoofer in the same positions as
in example (1).
• It is best to place the surround speakers
directly at the side or slightly to the front
Surround
of the viewing position, and 60 to 90 cm
speakers
above the ears.
• Same
installation method (1).
Using dipolar speakers for the surround back speakers as well is more
60°
effective.
Surround back speakers • The signals from the surround channels reflect off the walls as shown on the
diagram at the left, creating an enveloping and realistic surround sound
