Speaker placement
Ideal speaker placement varies depending on the size
of your room and the wall coverings. Here, only typical
example of speaker placement and recommenda-
tions are shown.
Important points regarding speaker placement
Front left and right speakers and center speaker
• Place these three speakers at the same height from
the floor.
• Place each speaker so that sound is aimed at the
location of the listener’s ears when at the listening
position.
Surround left and right speakers
• Place these speakers so that their height is 1 meter
higher than that of the listener’s ears.
Surround back left and right speakers
• These speakers are required for enjoying THX Sur-
round EX audio.
• Place these speakers behind the listener so that the
angle between each speaker and the listener is ap-
proximately 30 degrees.
• Place these speakers so that their height is 1 meter
higher than that of the listener’s ears.

Before connecting the speakers, place them correctly
by consulting the instruction manuals that came with
them.
For surround playback, the configuration and place-
ment of your speakers are very important.
For THX surround EX playback, we recommend that you
use a THX speaker system that is certified by Lucasfilm
Ltd.
Ideal speaker configuration
• Front right and left speakers
• Center speaker
Produces a rich sound image by serving as a sound
source for the front right and left speakers and en-
hancing the sonic movement.
• Surround right and left speakers
Adds three-dimensional sonic movement and pro-
duces environmental sound associated with the
background and effect sound for each scene.
• Surround back right and left speakers
Required for enjoying THX Surround EX audio.
• Subwoofer
Produces powerful and heavy bass.
Minimum speaker configuration for surround
sound playback
• Front right and left speakers
• Surround right and left speakers
The sound recorded for the center speaker and the
subwoofer will be properly distributed to the front right
and left speakers and the surround right and left
speakers for optimized surround playback.

Subwoofer
A subwoofer is recommended for the highest bass ef-
fect.
Most dipoles have an arrow on them to indicate their
orientation towards the screen. So for the side dipoles,
the arrows point forward. For the back dipoles, the ar-
rows should point towards each other to achieve the
correct acoustical phasing in the room.
