Features
Plus One Woofer Cones: Each speaker uses a cone larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One design offers greater bass output and an increase in efficiency.
Mounting: Without an adapter, the woofers fit standard 6¾" applications. Given their required cutout, they will also fit 6½" applications without an adapter, but new screw holes must be drilled. Using the included adapter brackets they can be mounted in a wide variety of 6½" and 6¾" applications, without any modification. Please enter your vehicle information to confirm fit.
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.
Tweeter Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:
- I-Mount: The tweeters can be surface-mounted or flush-mounted with JBL's innovative 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: Flush mounting uses the threaded flush-mount housing and plastic locking nut. 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 adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
- Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the existing 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 ?". Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Crossover: The input and output wires are attached to the crossover. The 8" input wires are not terminated (tinned bare wire). Both the woofer and tweeter output wires are 8" long and terminated with quick slides to easily attach to the drivers. A switch on each crossover allows you to adjust the tweeter output level; choose 0 dB (flat) or +3 dB.

- Width: 3⅞" (4⅛" including wires)
- Height: 1"
- Depth: 1⅞"

The speaker fit great in my 2016 mx-5 Miata. In fact the tweeters fit into the existing Bose tweeter housing. Pop the Bose out of its housing and the tweeter friction fits. The bracket holes in the provided adapter need to be enlarged by about 2mm to fit with the stock screw locations.
