eft and Right Front Channels
For left and right front channels, place one satellite to the left
and another to the right of the television, as shown in Figure 1.
Since the speakers are magnetically shielded, you can place
them very close to the TV without worrying about the magnetic
field distorting the picture.
Center Channel
For the center channel, place the speaker directly on top of,
or below, your television. Use a shelf or one of the included wall
brackets if the television does not provide a stable platform.
Surround Channels
For left and right surround channels, place one speaker on the left
and another on the right, to the side of or slightly behind the listening
area. The surround speakers should be mounted at a height of
between 5 ft. (1.5m) and 7 ft. (2m).
Subwoofer
Since the installation of a subwoofer can be somewhat more compli-
cated than installing full-range speakers, it is essential that you read
this section very carefully prior to connecting the subwoofer to your
system. Should you have questions relating to installation, it is advis-
able to call either your dealer or JBL’s Customer Service Department
for advice.
The performance of the subwoofer is directly related to its placement
in the listening room and how the subwoofer is aligned with the
satellite speakers. Setting the volume of the subwoofer in relation
to the left and right speakers is also of critical importance because
it’s essential that the subwoofer integrate smoothly with the entire
system. Setting the subwoofer’s volume level too high will result in
an overpowering, boomy bass. Setting the volume level too low will
negate the benefits of the subwoofer.
Here are several additional facts on installation that may prove use
-
ful. It is generally believed that low frequencies (below 125Hz) are
nondirectional and, therefore, placement of a subwoofer within any
listening room is not critical. While in theory it is true that the larger
wavelengths of extremely low frequencies are basically nondirec-
tional, the fact is that, when installing a subwoofer within the limited
confines of a room, reflections, standing waves and absorptions gen-
erated within the room will strongly influence the performance of any
subwoofer system. As a result, specific location of the subwoofer
becomes important, and we strongly recommend that you experiment
with placement before choosing a final location. Placement will
depend upon your room (for example, whether or not your room
permits placement of the subwoofer near either satellite) and the
amount and quality of bass required.
