Component Placement
Because of the JBL Component System’s
small size and extremely versatile mount-
ing options, there are an almost infinite
number of placement options to achieve
excellent sound quality in any vehicle.
Please consider the following state-
ments to help you get the most from
your system.
1. The most spacious stereo image is
achieved when the left and right
speaker systems are placed as far apart
as possible.
2. The best center image will be achieved
when the distance from the left speaker
and the right speakers are as equal as
possible from your listening position.
This is most easily achieved by placing
the speakers as far forward as possible.
3. Treble is directional in nature. This
means that high frequencies are reduced
as you move off the tweeter's axis. The
angle mounts will allow the tweeters to
be pointed across the car to the listener
on the opposite side. This will make each
listener slightly off-axis to the tweeter that
is closest to that listener, which helps to
compensate for the fact that the listener is
always closer to one tweeter than to the
other (see Figure 6).
The best system integration is achieved
when the tweeter is mounted close to the
midwoofer speaker. This helps smooth
the transition from the midrange and
tweeter at the crossover point.
Choosing mounting locations that satisfy
all of the above criteria will provide the
most satisfying performance.

System Design
There are a variety of system options
available with the Component System.
The simplest configuration is to use them
full range with their built-in passive
crossovers by connecting them to the out-
put of a head unit or an amplifier (Figures
7 and 8).
A more advanced system design can be
achieved by adding a Decade,™ GT,
Power, GTi, or equivalent subwoofer
to your component system. In this case
the component system will be used as
high and midbass frequency drivers and
should have their extremely low frequen-
cies blocked by electrical means. Active or
passive crossovers can be used in order
to achieve the best system fidelity and
widest dynamic range. Crossover fre-
quency recommendations are given in
the Specifications.
