Unpacking the Subwoofer  
If you suspect damage from transit, report it immediately to your dealer. Keep  
the shipping carton and packing materials for future use.  
PLACEMENT  
Since the installation of a subwoofer can be somewhat more complicated than  
installation of 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 your installation, it is advisable to call either your dealer  
or JBL’s Customer Service Department for advice.  
PRIMARY  
LISTENING  
AREA  
The performance of the subwoofer is directly related to its placement in the  
listening room and how you align the subwoofer with its satellite speakers.  
Setting the volume of the subwoofer in relationship to the left and right speakers  
is also of critical importance because it is essential that the subwoofer inte-  
grate smoothly with the entire system. Setting the subwoofer’s volume level  
too high will result in overpowering, boomy bass. Setting the volume level too  
low will negate the benefits of the subwoofer.  
Figure 1. This example shows the subwoofer positioned behind the  
right-channel satellite speaker to re-create the actual location of  
bass instruments in an orchestra and/or add impact to  
movie soundtracks.  
Here are several additional facts on installation that may prove useful.  
It is generally believed by most audio authorities 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 wave-  
lengths of extremely low frequencies are basically nondirectional, the fact is  
that, when installing a subwoofer within the limited confines of a room, reflec-  
tions, standing waves and absorptions generated 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 and the amount and quality of bass  
required (for example, whether or not your room permits placement of the  
subwoofer near either satellite).

If you have a Dolby Digital or DTS receiver/processor with a low-frequency-  
effects (LFE) or subwoofer output:  
If your receiver/processor does not have subwoofer outputs for the left and  
right channels or an LFE output, connect speaker wire from your receiver/  
amplifier to your speakers and subwoofer using two sets of speaker wire:

OPERATION  
MAINTENANCE AND SERVICE  
Power On  
The enclosure may be cleaned using a soft cloth to remove fingerprints or to  
wipe off dust.  
Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the  
back of the receiver.  
Initially set the Subwoofer-Level Control ¢ to the “min” position.  
The grille may be gently vacuumed. Stains may be removed with an aerosol  
cleaner, following its instructions. Do not use any solvents on the grille.  
Turn on your sub by pressing the Power Switch ª on the rear panel.  
All wiring connections should be inspected and cleaned or remade periodically.  
The frequency of maintenance depends on the metals involved in the connections,  
atmospheric conditions and other factors, but once per year is the minimum.  
Turn on your entire audio system and start a CD or movie soundtrack at a  
moderate level.  
If a problem occurs, make sure that all connections are properly made and  
clean. If a problem exists in one loudspeaker, reverse the connection wires to  
the left and right system. If the problem remains in the same speaker, then the  
fault is with the loudspeaker. If the problem appears in the opposite speaker,  
the cause is in another component or cable. In the event that your subwoofer  
ice center near you.  
Auto On/Standby  
With the Power Switch ª in the “on” position, the Power Indicator LED ∞  
will remain backlit in red or green to indicate the On/Standby mode of the  
subwoofer.  
RED = STANDBY (No signal detected, Amp Off)  
GREEN = ON (Signal detected, Amp On)  
When the Auto Switch  
§
is in the “auto” position, the subwoofer will auto-  
matically enter the Standby mode after approximately 10 minutes when no sig-  
nal is detected from your system. The subwoofer will then power ON instantly  
when a signal is detected. During periods of normal use, the Power Switch ª  
may be left on. You may turn off the Power Switch ª for extended periods of  
non-operation, e.g., when you are away on vacation. If the Auto Switch § is in  
the “on” position, the subwoofer will remain on.  
Adjust Gain  
Turn your Subwoofer-Level Control ¢ up to the halfway position. If no sound  
emanates from the subwoofer, check the AC-line cord and input cables. Are the  
connectors on the cables making proper contact? Is the AC plug connected to  
a “live” receptacle? Has the Power Switch ª been pressed to the “on” posi-  
tion? Once you have confirmed that the subwoofer is active, proceed by play-  
ing a CD, record or cassette. Use a selection that has ample bass information.  
Set the overall volume control of the preamplifier or stereo to a comfortable  
level. Adjust the Subwoofer-Level Control ¢ until you obtain a pleasing blend  
of bass. Bass response should not overpower the room but rather be adjusted  
so there is a harmonious blend across the entire musical range. Many users  
have a tendency to set the subwoofer volume too loud, adhering to the belief  
that a subwoofer is there to produce lots of bass. This is not entirely true. A  
subwoofer is there to enhance bass, extending the response of the entire sys-  
tem so the bass can be felt as well as heard. However, overall balance must  
be maintained or the music will not sound natural. An experienced listener will  
set the volume of the subwoofer so its impact on bass response is always  
there but never obtrusive.  
Phase Control  
The Phase Switch determines whether the subwoofer speaker’s pistonlike  
action moves in and out with the main speakers, 0˚, or opposite the main  
speakers, 180˚. Proper phase adjustment depends on several variables such  
as room size, subwoofer placement and listener position. Adjust the Phase  
Switch to maximize bass output at the listening position.  
Crossover Adjustment  
The Crossover Adjustment Control determines 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 and 100Hz. This will concentrate the subwoofer’s  
efforts on the ultradeep bass sounds required by today’s films and music.  
If you are using smaller bookshelf speakers that do not extend to the lower  
bass frequencies, set the Crossover Adjustment Control to a higher setting,  
between 120Hz and 150Hz.  
NOTE: This control will have no effect if the LFE/Input is used. If you have  
a Dolby Digital or DTS processor/receiver, the low-pass frequency is set by the  
processor/receiver. Consult your owner’s manual to learn how to view or  
change this setting.
