READ FIRST! Important Safety Precautions!
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings.
Install in accordance with the manufacturer’s
instructions.
8. Do not install near any heat sources such
as radiators, heat registers, stoves or other
apparatus (including amplifiers) that produce
heat.
9. Do not defeat the safety purpose of the
polarized or grounding-type plug. A polarized
plug has two blades with one wider than the
other. A grounding-type plug has two blades
and a third grounding prong. The wide blade
or the third prong are provided for your safety
.
If the provided plug does not fit into your out-
let, consult an electrician for replacement of
the obsolete outlet.
10. Protect the power cord from being
walked on or pinched, particularly at plugs,
convenience receptacles and the point
where they exit from the apparatus.
11.
Only use attachments/accessories
specified by the manufacturer.
12. Use only with the cart, stand, tripod,
bracket or table specified by the
manufacturer or sold with the
apparatus. When a cart is used,
use caution when moving the
cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during lightning
storms or when unused for long periods
of time.
14. Refer all servicing to qualified service
personnel. Servicing is required when the
apparatus has been damaged in any way,
such as power-supply cord or plug is dam-
aged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not
operate normally, or has been dropped.
15. Do not use attachments not recommended
by the product manufacturer, as they may
cause hazards.
16. This product should be operated only
from the type of power source indicated on
the marking label. If you are not sure of the
type of power supply to your home, consult
your product dealer or local power company.
For products intended to operate from bat-
tery power or other sources, refer to the
operating instructions.
17. If an outside antenna or cable system
is connected to the product, be sure the
antenna or cable system is grounded so as
to provide some protection against voltage
surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/
NFPA 70, provides information with regard to
proper grounding of the mast and supporting
structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding
conductors, location of antenna-discharge
unit, connection to grounding electrodes, and
requirements for the grounding electrode.
See Figure A.
18. An outside antenna system should not be
located in the vicinity of overhead power
lines or other electric light or power circuits,
or where it can fall into such power lines or
circuits. When installing an outside antenna
system, extreme care should be taken to keep
from touching such power lines or circuits, as
contact with them might be fatal.
19. Do not overload wall outlets, extension
cords, or integral convenience receptacles,
as this can result in a risk of fire or electric
shock.
20. Never push objects of any kind into this
product through openings, as they may touch
dangerous voltage points or short-out parts,
which could result in a fire or electric shock.
Never spill liquid of any kind on the product.
21. The apparatus shall not be exposed to
dripping or splashing, and no objects filled
with liquids, such as vases, shall be placed
on the apparatus.
22. Do not attempt to service this product
yourself, as opening or removing covers may
expose you to dangerous voltage or other
hazards. Refer all servicing to qualified
service personnel.
23. When replacement parts are required,
be sure the service technician has used
replacement parts specified by the manufac-
turer or that have the same characteristics
as the original part. Unauthorized substitu-
tions may result in fire, electric shock or
other hazards.
24. Upon completion of any service or repairs
to this product, ask the service technician to
perform safety checks to determine that the
product is in proper operating condition.
25. The product should be mounted to a
wall or ceiling only as recommended by
the manufacturer.

triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: To reduce the risk of electric shock, 
do not remove cover (or back). 
No user-serviceable parts inside. 
Refer servicing to qualified service personnel.
CAUTION: To prevent electric shock,
do not use this (polarized) plug with 
an extension cord, receptacle or other outlet 
unless the blades can be fully inserted to 
prevent blade exposure.
T he lightning flash with arrowhead symbol,

“dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to constitute 
a risk of electric shock to persons.

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.
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.
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).
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.
