Before you connect the speakers, place each speaker in
its respective location. Speaker positioning is very
important as it affects the overall sound quality of the
system. Place the speakers in locations that will
optimize the sound quality at your listening position.
Refer to the illustration below.
The position of the subwoofer is not as critical as the
position of the other speakers because sub-bass
sounds are not very directional. Refer to “Installing the
subwoofer” for more information.
Note
• Placing the speakers too close to a CRT-type TV
may impair the picture color or cause a buzzing
noise. In this case, move the speakers at least 20 cm
(8") away from the TV. This is not an issue with LCD
and plasma TVs.
Installing the front, center, and
surround speakers
Front speakers:
Place the two front speakers on the
left and right sides of the TV, at approximately the
same height as the TV, facing directly forward.
Surround speakers: Place the left and right
surround speakers behind your listening position,
facing slightly inward, about 1.8 meters (approx. 6 ft.)
above the floor.
You can place the front and surround speakers on
tables or other supports, or mount them on the walls.
For more information, see “Wall-mounting the front
and surround speakers” on page 3.
Center speaker: Place the center speaker centrally
between the front speakers, facing directly forward.
Installing the subwoofer
Place the subwoofer on the outside of either the right
or the left front speaker, as shown in
A and B .
The placement shown in C is also possible, however, if
the subwoofer is placed directly facing a wall and your
listening position is in the center of the room, you may
not be able to obtain enough bass sound from the
subwoofer. This is because “standing waves” are
forming between the two parallel walls and cancelling
out the bass sounds. In this case, position the
subwoofer at an angle to the wall. It may be necessary
to break up parallel wall surfaces by placing
bookshelves, etc., along them.
