Placement  
As a general rule, bass  
response increases as a  
subwoofer is placed closer  
to a wall. Therefore, bass  
output is maximized when  
the subwoofer is placed in  
a corner.  
• It is also recommended  
that the subwoofer be  
positioned along the  
same wall as the front  
loudspeakers.  
Low-frequency sounds are  
normally omnidirectional,  
meaning the listener cant  
tell where they are generated  
from. However, frequencies  
between 75Hz – 150Hz can  
be localized, especially at  
higher volume levels.  
Positioning your subwoofer  
as recommended will provide  
the most natural soundstage  
and imaging from your loud-  
speaker system.  
Remember that these are just  
guidelines. Since every listen-  
ing room is different, JBL  
strongly recommends experi-  
menting with the positioning  
of your subwoofer to obtain  
the most pleasing results in  
your room. One technique that  
can help you find the ideal  
subwoofer location is to tem-  
porarily place the subwoofer  
near the main listening loca-  
tion. Then move around the  
room and determine where you  
hear the most pleasing bass  
performance. This would then  
be the ideal location for the  
subwoofer.

Operation  
Level Control  
Video Contour  
Power  
The subwoofer Level Control,  
located on the front panel,  
adjusts the volume of the  
subwoofer relative to the rest  
of the system. Proper level  
adjustment depends on several  
variables such as room size,  
subwoofer placement, type of  
main speakers and listener  
position. Adjust the subwoofer  
level so that the volume  
of the bass information is  
pleasing to you.

The green LED will illuminate  
when the video-contour switch  
is on.  
The video-contour switch,  
located on the front panel,  
optimizes the subwoofers  
performance for movie listen-  
ing. When the video-contour  
switch is on, the subwoofers  
performance is tailored to  
deliver the impact and  
When the unit is plugged in  
and power is on and no signal  
is received, the LED on the  
front of the unit will turn red.  
When a signal is present, the  
LED will turn green. Note:  
It will take several minutes  
for the LED to turn from green  
to red after the input signal  
to the subwoofer is removed.  
Due to JBLs unique, high-  
efficiency digital-amplifier  
design, power consumption is  
minimal when the subwoofer  
is not receiving a signal. Of  
course, the subwoofer can be  
turned off, whenever desired.  
Crossover Adjustments  
High-Pass Control  
• If you hooked up your sub-  
woofer as shown in Hookup 4  
on page 5, you also have  
the capability of adjusting  
the high-pass frequency.  
The high-pass control  
determines the frequency at  
which the main speakers  
will start reproducing  
sounds. If your main speak-  
ers can comfortably repro-  
duce some low-frequency  
sounds, also set this  
control to a lower frequency  
setting, between 50Hz –  
100Hz. This will concentrate  
the subwoofers efforts to  
the ultradeep bass sounds,  
while your main speakers  
continue to reproduce the  
mid-bass information. If you  
are using smaller bookshelf  
speakers that do not extend  
to the lower bass frequencies,  
set the high-pass crossover  
control to a higher setting,  
between 125Hz – 180Hz.  
With this setting, your main  
speakers will not have the  
burden of reproducing any  
low-frequency sounds.  
• If you hooked up your sub-  
woofer as shown in Hookup 1  
on page 3, the high-pass  
frequency is fixed at 180Hz.  
• If you hooked up your  
subwoofer as shown in  
amplifier incorporates a  
high-pass crossover, your  
main speakers will continue  
to get a full-range signal.  
Low-Pass Control  
The low-pass control deter-  
mines the highest frequency at  
which the subwoofer reproduces  
sounds. If your main speakers  
can comfortably reproduce  
some low-frequency sounds,  
set this control to a lower  
frequency setting, between  
50Hz – 100Hz. This will  
concentrate the subwoofers  
efforts on the ultradeep bass  
sounds required by todays  
films and music. If you are
