Connecting Speakers; Ideal Speaker Configuration; Minimum Speaker Configuration For Surround Sound Playback; Speaker Placement - Onkyo TX-DS898 Instruction Manual

Connecting speakers

Before connecting the speakers, place them correctly by consulting
the instruction manuals that came with them.
For surround playback, the configuration and placement 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 enhancing the sonic
movement.
• Surround right and left speakers
Adds three-dimensional sonic movement and produces
environmental sound associated with the background and effect
sound for each scene.
• Surround back right and left speakers
Required for enjoying THX Surround EX, DTS-ES Matrix 6.1,
or DTS-ES Discrete 6.1 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 for optimized
surround playback.

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 recommendations are shown.
In order to create the optimum conditions for the best sound quality,
be sure to place all the speakers so that the greatest difference
between the distances of each speaker to the listening position is
less than 20 feet.
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 speakers
• Place these speakers behind the listener so that the angle
between each speaker and the listener is approximately 30
degrees.
• Place these speakers so that their height is 3 feet (1 meter)
higher than that of the listener's ears.

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 arrows should point towards each other to
achieve the correct acoustical phasing in the room.
