Thank you for purchasing a

JBL Grand Touring 2-way

Component System. We’ve

organized this manual to make

read through it completely

before proceeding. If, after

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.
