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 or digital TV, you can enjoy Dolby Pro Logic IIx, DTS Neo:6, or Onkyo’s original DSP listening modes.
You can also enjoy THX Surround EX (THX-certified THX speaker system recommended).
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 dis-
tinct and providing a full sound 
image. In movies it’s used 
mainly for dialog.
Position it close to your TV fac-
ing 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 position, the shape of your 
listening room, and your listening posi-
tion. 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 
subwoofer, while playing a movie or 
some music with good bass, experiment 
by placing your subwoofer at various 
positions within the room, and choose 
the one that provides the most satisfying 
results.
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 to 
3 feet (60 to 100 cm) above ear level. Ideally they should be equidis-
tant from the listener.
Surround back left and right speakers
These speakers are necessary to enjoy Dolby Digital 
EX, DTS-ES Matrix, DTS-ES Discrete, THX Surround 
EX, etc. They enhance the realism of surround sound 
and improve sound localization behind the listener. 
Position them behind the listener about 2 to 3 feet (60 
to 100 cm) above ear level.
Front high left and right speakers
These speakers are necessary to enjoy Dolby Pro Logic IIz Height, 
Audyssey Dynamic Surround Expansion™, etc.
They enhance significantly the spatial experience.
Position them at least 3.3 feet (100 cm) above the front left and 
right speakers (and as high as possible). Although it is acceptable 
to place left and right at an angle slightly wider than the front left 
and right speakers.
