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.
