About This Manual
Because of the performance capability
of your GTi Competition Series product,
and the variety of potential system
configurations, we strongly recommend
that you have the system professionally
installed. You will also get a better
warranty if your equipment is pro-
fessionally installed by an authorized
GTi dealer and you have your warranty
card stamped. This manual provides
information on installation and usage to
help a skilled technician get the most from
your GTi Competition Series product. This
manual does not cover basic information
about installation which is common
knowledge to a professional installer,
except for information which is unique to
the 600GTi Woofer/Midbass.
If you feel you possess the necessary
skills, and prefer to install the equipment
yourself, this manual will provide you with
the necessary specifics to properly use the
600GTi in typical installations. Consult
your JBL dealer, or a qualified technician,
for more information.
Autosound at its Best
The 600GTi Woofer/Midbass is built to
meet the same rigorous standards of con-
struction and performance that have long
established JBL's renowned home and
professional speaker systems. The 600GTi
Woofer/Midbass incorporates a high poly-
mer laminate pulp cone which is especially
suited to the unique acoustic and environ-
mental requirements for an automotive
woofer/midbass unit. The 600GTi has
been engineered to provide excellent
power handling, optimum transient attack
and balanced frequency response.
The 600GTi Woofer/Midbass uses a
cast frame to secure the powerful Barium
Ferrite Magnet based motor structure.
The rigid cast frame prevents resonance
and flexing in the frame thus reducing
distortion. In the 600GTi, the high con-
centration of magnetic power generated
by the large motor structure is coupled to a
2" Edge-wound Aluminum Wire High
Temperature Fiberglass Voice Coil. This
powerful motor structure delivers dynamic
midbass while its large diameter and
3

fiberglass former assure extremely high
thermal power handling.
A high polymer laminate cone is used
because of its excellent combination of
high stiffness and low mass. This lets the
600GTi reproduce the powerful attacks of
percussive bass with immediacy and
impact.
The cone motion of these high
excursion designs is controlled by an
Aromatic Polyamid Fiber spider. Because
it is seven times stronger than con-
ventional spiders, this new material is able
to control the extreme motion of the cone
while maintaining musical accuracy with
incredible ruggedness.
What does all this technology add up
to? A driver with smooth frequency
response, excellent transient response,
and high output capability all in a rugged
package. The result is exceptionally
dynamic and accurate music reproduction
over the bass and midbass frequency
range that cuts through road noise and
provides a solid musical foundation.
Designing Your System
The overall quality of any system
design is a result of how well all of the
components work together, not just the
result of the performance of any one
component. JBL GTi Series Tweeter,
Woofer/Midrange, Coupled Component
and Subwoofer Transducers are the ideal
companion products to your 600GTi
Woofer/Midbass. Each of the GTi
Competition Series products are designed
to complement the others to provide the
highest performance with the simplest and
most predictable system design. To use
the 600GTi as the woofer or midbass
transducers in a high quality system, we
recommend you use a high quality active
crossover such as JBL's GTX47, GTX4 or
GTX2 to provide optimum matching to
your subwoofer or midrange loudspeaker.
If you prefer passive crossovers, we
recommend that you use only high quality
audiophile grade film-type capacitors and
low DCR inductors to get the most out of
your system. The most popular system
configuration is a hybrid using an active
crossover for the subwoofer to woofer/
midbass crossover point, a second active
crossover for the midbass to midrange
crossover, and a passive crossover for the
midrange to tweeter crossover. Your GTi
Competition series dealer is uniquely
qualified to help guide you on the best
system configuration for your needs.
Component Placement
The location of each of the
loudspeakers plays a vital role in achieving
proper frequency response and spacious
imaging. Because the 600GTi Woofer/
Midbass have an extremely wide and
smooth dispersion pattern, excellent
performance may be achieved in any
vehicle. Due to the wide variety of
vehicles, there is not one “right” way to
locate the 600GTi, however knowledge of
the following considerations will help you
get the most from your system:
1.
The most spacious stereo image is
achieved when the speakers are placed
as wide apart as possible. The lower
the crossover frequency is set, the
