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 Blu-ray Discs or 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 lis-
tening modes.
You can also enjoy THX Surround EX (THX-certified THX speaker system recommended).
Enjoying Home Theater
a b Front speakers (Left and Right)
These output the overall sound. Their role in a home theater is to pro-
vide 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.
c
Center speaker
This speaker enhances the front 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 facing forward at about ear 
level, or at the same height as the front speakers.
d e Surround speakers (Left and Right)
These speakers are used for precise sound positioning and to add real-
istic 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 equidistant from the listener.
f
Subwoofer(s)
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 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.
g h Surround back speakers (Left and Right)
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.
i j Front high speakers (Left and Right)
These speakers are necessary to enjoy Dolby Pro Logic IIz Height, and 
Audyssey DSX™. They significantly enhance the spatial experience. 
Position them at least 3.3 feet (100 cm) above the front speakers (pref-
erably as high as possible) and at an angle slightly wider than the front 
speakers.
k l Front wide speakers (Left and Right)
These speakers are necessary to enjoy Audyssey DSX. They signifi-
cantly enhance the spatial experience. Position them well outside of the 
front speakers. See also http://www.audyssey.com/technology/dsx.html 
about optimum speaker placement for Audyssey DSX.

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.
