OWNER’S GUIDE  
 
INTRODUCTION  
JBL® ES150P/ES250P Powered Subwoofers  
For more than 60 years, JBL has been providing audio equipment to  
concert halls, recording studios and movie theaters around the  
world, and has become the hands-down choice of leading recording  
artists and sound engineers.  
With the JBL ES Series, innovative technologies such as titanium-  
laminate-dome tweeters, Elliptical Oblate Spheroidal (EOS) wave-  
guides and PolyPlas transducer reinforcement are available to you.  
Enjoy!  
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 your dealer or distributor for  
advice.  
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 sound-  
tracks.  
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 integrate  
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.  
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 wavelengths of extremely  
low frequencies are basically nondirectional, the fact is that, when  
installing a subwoofer within the limited confines of a room,  
reflections, 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:  
Set LFE/Normal switch to “LFE.”  
If your receiver/processor does not contain a Dolby Digital  
or DTS processor, but has subwoofer outputs:  
Set line-level/LFE switch to  
“Normal.”  
NOTE: If your receiver/processor  
has only one sub out, you may  
use either the L or R input.

OPERATION  
MAINTENANCE AND SERVICE  
Power On  
The enclosure may be cleaned using a soft cloth to remove finger-  
prints 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.  
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.  
2
Initially set the Subwoofer-Level Control  
to the “min” position.  
5
Turn on your sub by pressing the Power Switch  
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.  
Auto On/Standby  
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 ever needs  
service, contact your local JBL dealer or distributor, or visit  
5
With the Power Switch  
in the ON position, the Status LED on the  
top will remain lit 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)  
The subwoofer will automatically enter the Standby mode after  
approximately 10 minutes when no signal is detected from your  
system. The subwoofer will then power ON instantly when a signal is  
5
detected. During periods of normal use, the Power Switch  
can be  
5
left on. You may turn off the Power Switch  
for extended periods  
of nonoperation, e.g., when you are away on vacation.  
Adjust Gain  
Turn your Subwoofer-Level Control  
2
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  
5
Power Switch  
been pressed to the “On” position? Once you have  
confirmed that the subwoofer is active, proceed by playing 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  
2
comfortable level. Adjust the Subwoofer-Level Control  
until you  
obtain a pleasing blend of bass. Bass response should not over-  
power 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 system 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  
0
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  
3
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/Normal Selector  
is set to LFE. 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.
