The Peak Dynamic Power is measured by recording
the highest peak-to-center voltage produced by the
power amplifier with its limiters disabled, across
the output of a resistive load equal to minimum
impedance of the transducer, using a 50Hz sine wave
burst, 3 cycles on, 17 cycles off.

READ FIRST! Important Safety Precautions!
SPEAKER 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 nor-
mally omnidirectional, meaning
the listener can’t 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.
Remember that these are just
guidelines. Since every listening
room is different, JBL strongly
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
pleasing bass performance.
This would then be the ideal
location for the subwoofer.
SPEAKER CONNECTION
When we designed the L8400P
powered subwoofer, our goal
was to offer the user the best
possible performance com-
bined with the most flexible
and complete installation
options. Please look over the
following three examples to
determine which description
best matches your system and
follow the corresponding
hookup instructions.
To use the binding-post
speaker terminals with bare
wire, unscrew the collar until
the hole through the center
post is visible under the collar.
Insert the bare end of the wire
through the hole in the post,
then screw the collar back
down until the connection is
tight. The holes in the center
of the collars are intended for
banana-type connectors. To
comply with European CE
certification, these holes are
blocked with plastic inserts at
the point of manufacture. To
use banana-type connectors
requires the removal of the
inserts. Do not remove these
inserts if you are using the
product in an area covered by
the European CE certification.
Speakers and electronics
have corresponding positive
(+) and negative (–) terminals.
It is important to connect both
speakers identically: positive
(+) on the speaker to positive
(+) on the amplifier and nega-
tive (–) on the speaker to
negative (–) on the amplifier.
Wiring “out of phase” results
in thin sound, weak bass and
a poor stereo image.
With the advent of multichan-
nel surround sound systems,
connecting all of the speakers
in your system with the cor-
rect polarity remains equally
important in order to preserve
the proper ambience and
directionality of the program
material.

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 reg-
isters, 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 outlet, consult an electrician
for replacement of the obsolete
outlet.
10. Protect the power cord from
being walked on or pinched, partic-
ularly at plugs, convenience recep-
tacles and the point where they exit
from the apparatus.
11.
Only use attachments/acces-
sories 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/appa-
ratus 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
damaged, 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 battery 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 sys-
tem 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 support-
ing 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 cir-
cuits, 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 volt-
age points or short-out parts that
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 serv-
ice personnel.
23. When replacement parts are
required, be sure the service tech-
nician has used replacement parts
specified by the manufacturer or
that have the same characteristics
as the original part. Unauthorized
substitutions may result in fire, elec-
tric 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 prod-
uct is in proper operating condition.
25. The product should be mounted
to a wall or ceiling only as recom-
mended by the manufacturer.
