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.  
Low-frequency sounds are nor-  
mally omnidirectional, meaning  
the listener cant tell where they  
are generated from. However,  
frequencies between 75Hz and  
150Hz can be localized, espe-  
cially at higher volume levels.  
Positioning your subwoofer as  
recommended will provide the  
most natural soundstage and  
imaging from your loudspeaker  
system.  
recommends experimenting  
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 temporarily place  
the subwoofer near the main  
listening location. Then move  
around the room and determine  
where you hear the most

This would then be the ideal

guidelines. Since every listening

bare ends of the two leads  
that will be connected to each  
terminal on the receiver/  
amplifier, as shown in the  
diagram. This procedure  
should be done only four times  
(involving a total of eight bare-

Power  
When the unit is plugged in  
and the power switch is on  
and no signal is received, the  
LED on the top of the unit will  
turn red. When a signal is  
present, the LED will turn  
green.  
Note: It will take several min-  
utes for the LED to turn from  
green to red after the input  
signal to the subwoofer is  
removed. Due to JBL’s unique  
high-output, high-efficiency  
amplifier design, power con-  
sumption is minimal when the  
subwoofer is not receiving a  
signal. Of course, the sub-  
woofer can be turned off,  
whenever desired, if you do  
not wish to leave it in auto  
(standby) mode.  
Level Control  
The subwoofer Level Control  
adjusts the volume of the  
subwoofer relative to the rest  
of the system. Proper level  
adjustment depends on sev-  
eral variables such as room  
size, subwoofer placement,  
type of main speakers and  
position. Adjust the subwoofer  
level so that the volume of the  
bass information is pleasing  
to you.  
Crossover Adjustments  
The Crossover Frequency  
Control determines the highest  
frequency at which the sub-  
woofer reproduces sounds. If  
your main speakers can com-  
fortably reproduce some low-  
frequency sounds, set this  
control to a lower frequency  
setting, between 50Hz and  
100Hz. This will concentrate  
the subwoofers efforts on the  
ultradeep bass sounds

Phase Control  
The Phase Control determines  
whether the subwoofers pis-  
ton-like action moves in and  
out in phase with the main  
speakers or opposite the  
main speakers. There is no  
correct or incorrect setting.  
Proper phase adjustment  
depends on several variables  
such as subwoofer placement  
and listener position. Adjust  
the phase switch to maximize  
bass output at the listening  
position.  
If at some time in the future  
you happen to rearrange your  
listening room and move your  
speakers, you should experi-  
ment with the phase switch in  
both positions, and leave it in  
the position that maximizes  
bass performance.  
Remember, every system,  
room and listener is different.  
There are no right or wrong  
settings; this switch offers the  
added flexibility to adjust your  
subwoofer for optimum per-  
formance for your specific  
listening conditions without  
having to move your speakers.
