JBL continually strives to improve its products. New materials, production methods and design
refinements are introduced into existing models without notice as a routine expression of our design
philosophy. For this reason, JBL loudspeakers may differ in some respect from their published
specifications and descriptions, but will always equal or exceed the original specifications unless
otherwise stated.

SERVICE

Should your subwoofer ever need
service, return it to the JBL dealer
from whom it was purchased. If for
some reason this is impractical, in the
USA, call 800-336-4JBL for the
nearest warranty station.

Do not
return products to the JBL factory
without prior authorization.

MANUAL

G

SUB10

INTRODUCTION

Congratulations on choosing JBL
loudspeakers. Their highly accurate,
uncolored and balanced sound
character will greatly increase your
enjoyment of recorded music. We
build JBL speakers with careful
attention to detail, using only the
highest quality materials. They will
provide many years of excellent
performance.

Your G Sub10 is easy to set up. We
recommend that you take a few
minutes to read this owner's manual
before you begin, and that you follow
instructions carefully.

Amplified Subwoofer

Your G Sub10 subwoofer has both
line-level and speaker-level stereo
inputs for versatility and ease of use.
We've also provided speaker outputs
to let you hook up satellite speakers.
Adjustable level and crossover
controls let you balance the
subwoofer with your main speakers.

Poly-fiber Laminate Woofer

Provides tight bass and well-defined
sound reproduction without
harshness, stridency, or listener
fatigue.

Acoustically Optimized Cabinet

Optimized to produce an extended
and level bass response in
conjunction with the internal amplifier.
The cabinet may be placed either
vertically or horizontally. The grille
logo may be turned to match either
orientation of the subwoofer.

CONNECTIONS

CAUTION: Before making any
connections to your subwoofer,
make sure the power to your
entire system is OFF.

POWER

Plug the power cord into a grounded
wall outlet or the accessory outlet on
the back of your amplifier/receiver.

INPUTS

Your G Sub10 subwoofer has
both line-level and speaker-level
input connections. Review your
receiver/TV/source amplifier
instruction manual to see which
outputs your equipment provides,
then follow the appropriate
instructions below.

Line Input – Use the RCA (phono)
input jacks labeled "Line Input" when
connecting from a line-level device,
such as a pre-amp, crossover, signal
processor, or when using any of the
line-level outputs on the rear of your
receiver/TV/source amplifier. If your
receiver has a single RCA output for
sending the signal to the subwoofer,
you may connect it to both Right &
Left input jacks by using a "Y" adapter
(not included). Many stereo/ large
screen TVs have stereo (Right & Left)

RCA jacks for sending the signal to
external audio equipment. Your
subwoofer connects to these using
both the Right & Left input jacks
(see Figure 1).

Speaker Level Input (from
amplifier)

– Use these inputs when
connecting to the “Speaker Out”
(speaker mains) of the receiver/
TV/source amplifier. Run speaker
wires from the speaker output
terminals (usually coded red and
black) on the rear of the
receiver/TV/source amplifier to the
red and black input terminals labeled
"Speaker Level Input (from amplifier)"
on the subwoofer (see Figure 2).

Preparing the Hookup Wire

Your JBL dealer can recommend
suitable cables, or you can buy wire at
most hardware or electronic stores.
High-quality connectors and cable
offer consistent performance that does
not deteriorate over time. We
recommend #16 AWG two-conductor
insulated wire as a minimum size. If
your subwoofer is more than 30 feet
(10m) from your receiver/TV/source
amplifier, use larger diameter, lower
gauge wire.
