JBL 560GTI, 660GTI manual Specifications

WOOFER MOUNTING CONSIDERATIONS

•All woofers require a rigid baffle and isolation between the front and back of the speaker for best low-frequency extension.

•The 660GTi woofer may be used in an infinite baffle or in a small sealed enclosure with a volume equal to or larger than 1/8 ft3. The 560GTi woofer may be used in an infinite baffle or in a small sealed enclosure with a volume equal to or larger than 1/12 ft3.

•The GTi competition speaker systems include a choice of grille trim. See Figure 19 to change to the carbon fiber grille trim.

TWEETER MOUNTING CONSIDERATIONS

•Use the waveguides, if possible.

•The waveguide requires a hole 4" in diameter for mounting.

•Aim the tweeters at a point in between the two front-seat positions, if the waveguides will be mounted in the A-pillars or kick panels.

ADJUSTING THE CROSSOVER

•If you are bi-amping the speakers, remove the jumpers, as illustrated in Figure 20.

•If you are using the waveguides, move the switch to the “Waveguide” position.

•If you are not using the waveguide, move the switch to the “No Waveguide” position.

•After installing the system, set the “Tweeter Level” switch according to your preference.

See pages 14–19 for dimensions, mounting and wiring diagrams, Thiele/Small parameters and performance graphs.
