THANK YOU FOR CHOOSING JBL
For more than 50 years, JBL
has been involved in every
aspect of music and film
recording and reproduction,
from live performances to the
recordings you play in your
home, car or office.
We're confident that the JBL
system you have chosen will
provide every note of enjoy-

SPEAKER PLACEMENT

• As a general rule, bass
response increases as a sub-
woofer is placed closer to a
wall. Therefore, bass output
is maximized when the sub-
woofer is placed in a corner.
• It is also recommended that
the subwoofer be positioned
along the same wall as the
front loudspeakers.

SPEAKER CONNECTION

When we designed the Balboa
Sub powered subwoofer, our
goal was to offer the user the
best possible performance
combined with the most flexi-
ble 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
ment that you expected – and
that when you think about pur-
chasing additional audio
equipment for your home, car
or office, you will once again
choose JBL.
Please take a moment to regis-
ter your product on our Web
site at www.jbl.com.
Low-frequency sounds are
normally omnidirectional,
meaning the listener can't tell
where they are generated
from. However, frequencies
between 75Hz and 150Hz can
be localized, especially at
higher volume levels. Position-
ing your subwoofer as recom-
mended will provide the most
natural soundstage and
imaging from your loudspeaker
system.
Remember that these are just
guidelines. Since every listen-
ing room is different, JBL
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 ter-
minals have corresponding

connect both speakers identi-

JBL Consumer Products
strongly recommends experi-
menting with the positioning of
your subwoofer to obtain the
most pleasing results in your
room. One technique that can
help you find the ideal sub-
woofer location is to temporar-
ily place the subwoofer near
the main listening location.
Then move around the room
and determine where you hear
the most pleasing bass perfor-
mance. This would then be the
ideal location for the sub-
woofer.

amplifier and negative (–) 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 correct
polarity remains equally impor-
tant in order to preserve the
proper ambience and direc-
tionality of the program
material.
