About Home Theater
Thanks to the AV receiver’s superb capabilities, you can enjoy surround sound with a real sense of movement in your
own home—just like being in a movie theater or concert hall. With DVDs you can enjoy DTS and Dolby Digital. With
analog and digital TV you can enjoy Dolby Pro Logic IIx or Onkyo’s own DSP surround listening modes.
With the DTR-6.5 you can enjoy DVDs that feature THX Surround EX (THX-certified THX speaker system recom-
mended).
Enjoying Home Theater
Front left and right speakers
These output the overall sound. Their role in a home theater is to provide a solid
anchor for the sound image. They should be positioned facing the listener at about
ear level, and equidistant from the TV. Angle them inward so as to create a triangle,
with the listener at the apex.
Center speaker
This speaker enhances the front left
and right speakers, making sound
movements distinct and providing a
full sound image. In movies it’s used
mainly for dialog.
Position it close to your TV (preferably
on top) facing forward at about ear
level, or at the same height as the
front left and right speakers.
Subwoofer
The subwoofer handles the bass sounds of
the LFE (Low-Frequency Effects) channel.
The volume and quality of the bass output
from your subwoofer will depend on its posi-
tion, the shape of your listening room, and
your listening position. In general, a good
bass sound can be obtained by installing the
subwoofer in a front corner, or at one-third
the width of the wall, as shown.
Tip: To find the best position for your sub-
woofer, while playing a movie or some
music with good bass, experiment by plac-
ing your subwoofer at various positions
within the room, and choose the one that
provides the most satisfying results.
Surround back left and right speakers
These speakers are necessary to enjoy Dolby Digital EX, DTS-ES
Matrix, DTS-ES Discrete, and THX Surround EX (DTR-6.5 only). They
enhance the realism of surround sound and improve sound localization
behind the listener. Position them behind the listener about 2–3 feet (60–
100 cm) above ear level.
For the DTR-6.5, THX recommends that
they be placed equidistant from the listener,
creating a triangle, and that the angle at the
apex of the triangle is about 60 degrees.
Make sure that the listening position is within
the range of the speakers.

Surround left and right
speakers
These speakers are used for
precise sound positioning and
to add realistic ambience.
Position them at the sides of
the listener, or slightly behind,
about 2–3 feet (60–100 cm)
above ear level. Ideally they
should be equidistant from the
listener.
