THX speaker system setup

If you are using a THX certified subwoofer use the THX
INPUT jack on the subwoofer (if your subwoofer has one)
or switch the filter position to THX on your subwoofer.
See also THX Audio Setting on page 111 to make the
settings that will give you the best sound experience
when using the Home THX modes (page 58).

Some tips for improving sound quality

Where you put your speakers in the room has a big effect
on the quality of the sound. The following guidelines
should help you to get the best sound from your system.
• The subwoofer can be placed on the floor. Ideally, the
other speakers should be at about ear-level when
you're listening to them. Putting the speakers on the
floor (except the subwoofer), or mounting them very
high on a wall is not recommended.
• For the best stereo effect, place the front speakers 2
m to 3 m (6 ft. to 9 ft.) apart, at equal distance from
the TV.
• If you're using a center speaker, place the front
speakers at a wider angle. If not, place them at a
narrower angle.
• Place the center speaker above or below the TV so
that the sound of the center channel is localized at
the TV screen. Also, make sure the center speaker
does not cross the line formed by the leading edge of
the front left and right speakers.
• It is best to angle the speakers towards the listening
position. The angle depends on the size of the room.
Use less of an angle for bigger rooms.
• Surround and surround back speakers should be
positioned 60 cm to 90 cm (2 ft. to 3 ft.) higher than
your ears and tilted slight downward. Make sure the
speakers don't face each other. For DVD-Audio, the
speakers should be more directly behind the listener
than for home theater playback.
• If the surround speakers cannot be set directly to the
side of the listening position with a 7.1-channel
system, the surround effect can be enhanced by
turning off the Up Mix function (see Setting the Up
Mix function on page 62).
• Try not to place the surround speakers farther away
from the listening position than the front and center
speakers. Doing so can weaken the surround sound
effect.
