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.

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.

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:

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
