Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

FRP Frames: The fiberglass-reinforced plastic (FRP) frames used in the GTO series woofers resist warping, even when mounted on uneven surfaces. The nonmagnetic carbon composite has no impact on the motor structure and the plastic doesn't resonate.

High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.

Woofer Size Classification: These speakers are marketed as 6-1/2"; they will fit standard 6-1/2 speaker openings, but do not use the industry standard bolt pattern (then again, neither do many car manufacturers at this point). Without using an adapter bracket or drilling new screw holes, the speakers fit many standard 6-3/4 applications. The included metal brackets adapt the speakers to standard three hole 6-1/2 patterns. If new holes are drilled in the mounting surface of the car, no brackets are needed. Brackets are also included that fit select oversized 6-3/4 installations in a variety of vehicles.

Tweeters: The edge-driven soft dome tweeters can be mounted several different ways using the included hardware:

• I-Mount System: The tweeters can be surface- or flush-mounted with JBL's I-Mount system:
  • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
  • Flush Mount: Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and inserted into the hole. The large plastic locking nut is threaded onto the housing (from behind the mounting surface) to hold the assembly securely in place. When flush mounted, the tweeters may be angled for optimum imaging.
• Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
  • Bottom Mount: Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
  • Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
  • Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under a half inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Mounting Dimensions:

Crossover Connections: The passive crossovers feature screw terminal inputs and outputs; they will accommodate bare wire or spade connectors up to 0.315" wide.

Tweeter Level: A switch on each crossover allows you to adjust the output level of the tweeter; choose 0 dB (flat) or +3 dB.

Crossover Mounting: Each crossover can be mounted using two of the included screws through two holes in the base.

Crossover Dimensions:

• Length: 3.085"
• Width: 4.725"
• Height: 1.180"
