response to be completely optimized for
each combination.

What does all this technology add up

to? A Coupled Component

TM

system with

ideal frequency balance, excellent off axis
response, and high output capability in a
small, elegant package. The result is
exceptionally smooth and detailed music
reproduction over the full range of
frequencies and clean sound that cuts
through road noise.

These Coupled Components

TM

can 

be placed in stock locations yet still 
deliver the punch and performance of a
component system. The near-coincident,
low profile tweeter mounting and small
size of the driver allow these Coupled
Component

TM

systems to be mounted for

optimum imaging in ways that cannot
easily be achieved with separate
component systems.

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 woofer/
midbass or subwoofer transducers are
the ideal companion products to your 404
and 504GTi systems. 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 404 and 504GTi as the satellite
transducers in a high quality system, 
we recommend you use either a high
quality active crossover such as JBL’s
GTX47, GTX4 or GTX2 to provide
optimum matching to your subwoofer or
woofer/midbass 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/
midrange crossover point, and the passive
crossover included with your Coupled
Components

TM

for the woofer/midrange to

tweeter crossover. Your GTi Competition
Series dealer is uniquely qualified to help
guide you on the best system configuration
for your needs.

Coupled Component 

TM

Placement

The location of each of the

loudspeakers plays a vital role in achieving
proper frequency response and spacious
imaging. The near-coincident design of the
Coupled Components

TM 

gives the 404 and

504GTi systems an extremely wide and
smooth dispersion pattern. As a direct
result, excellent performance may be
achieved in any vehicle. Due to the wide
variety of vehicles, there is more than one
“right” way to locate the 404 and 504GTi.
Knowledge of the following considerations
will help you get the most from your
system:
