organized this manual to make

having read it, you decide that
you would rather leave installa-
tion to a professional, consult
your JBL Grand Touring Dealer.
Autosound at Its Best
Your JBL Component System is
built to meet the same rigorous
standards of construction and
performance that have long
established JBL’s renowned
home and professional speaker
systems.
Your Component System has
been designed using a combina-
tion of technologies that bring
high value to high performance.
The tweeter dome used in
your Component System tweeter
is manufactured from a
proprietary material known as
Titanium Composite. This
material combines the control
and damping of an advanced
polymer with the reinforcing
stiffness of vapor-deposited
titanium to prevent breakup at
high levels.
Similarly, the woofer cones are
manufactured with a proprietary
copolymer which is reinforced
with graphite in order to deliver
the clarity and effortless power
that have made JBL famous.
The pattern molded into this
material further stiffens it,
reducing breakup at high listen-
ing levels. This cone is sus-
pended by a heavy Butyl rubber
surround, which serves to absorb
any remaining cone resonances
for the clearest, most articulate
reproduction of voices and other
mid-range sounds. As a bonus,
the Butyl rubber surround is
impervious to temperature
extremes and humidity,
making it ideal for automotive
applications.
By following the installation rec-
ommendations and suggestions
included in this manual, you will
be assured of many years of
trouble-free enjoyment from
your Grand Touring series
loudspeakers.
