JBL 500GTi - Manual (Page 5)

Woofer/Midrange, and a laboratory-
optimized crossover. The most popular
system configuration is a hybrid using an
active crossover for the subwoofer to
midrange crossover point, 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 400 and 500GTi
have an extremely wide and smooth
dispersion pattern, excellent performance
may be achieved in any vehicle. Because
of the wide variety of vehicles, there is
not one “right” way to locate the 400 and
500GTi, 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 400 and 500GTi’s
are placed as wide apart as possible.
2. The best center image will be
achieved when the distance from the
left speaker to your left ear is as equal
as possible to the distance from the
right speaker to your right ear. This is
most easily achieved by placing the
400 and 500GTi as far forward as
you can.
3. The best system integration is
achieved when the woofer/midrange
is mounted close to the tweeter.
Installing the tweeter close to the
woofer/midrange helps smooth the
transition from woofer/midrange to
tweeter at the crossover point.
4. You will get the best frequency
response when the path from the
woofer/midrange and tweeter to
your ear is unobstructed.
5. Because of the high acoustic energy
capability of the 400 and 500GTi, they
must be securely mounted in a rigid
panel which is free from resonances,
rattles and air leakage.
Installation Warnings and Tips
• Be careful not to cut or drill into fuel
tanks, fuel lines, brake or hydraulic
lines, vacuum lines or electrical wiring
when working on your vehicle. Inspect
behind panels before you cut or drill.
• Be sure to check for clearance of
window, cranks and linkages when
mounting speakers in door panels.
• Do not use the 400 and 500GTi
unmounted. Failure to securely mount
this product could result in damage or
injury, particularly in the event of an
accident.
• Do not mount the 400 and 500GTi
where it will get wet.
• Always disconnect the ground wire
from the battery before doing any
work on the vehicle.
