Infinity Kappa 693CF 6x9" Two-Way Component Speakers

The Infinity Kappa 693CF is a 6 x 9-inch two-way component speaker system designed for vehicle owners replacing factory speakers with a separate woofer, tweeter, and external crossover layout. Its component design allows the tweeters to be mounted independently from the woofers for more flexible placement. The system is rated at 145 watts RMS and uses a 3-ohm nominal impedance.

This system is intended for vehicles with suitable 6 x 9-inch speaker locations and space for separate crossover networks. The 94 dB sensitivity rating helps it produce useful output from compatible factory or aftermarket power. An amplifier capable of operating with a 3-ohm speaker load is a practical match when using the system at higher listening levels.

The Kappa 693CF combines Plus One glass-fiber woofer cones with hi-roll rubber surrounds. The woofer construction is designed to provide a rigid, lightweight moving surface while the rubber surround supports cone movement. Its specified frequency response is 35 Hz to 40 kHz.

Separate 3/4-inch edge-driven silk dome tweeters handle the upper-frequency range. The included crossover networks provide a selectable 0 dB or -3 dB tweeter output setting, allowing adjustment based on tweeter location and cabin acoustics. Surface, flush, and factory-location mounting hardware gives installers several placement options.

The system also supports a future three-way configuration through its selectable 2-way/3-way crossover design. A compatible optional Kappa midrange can be added to expand the system beyond its supplied two-way arrangement. This makes the Kappa 693CF suitable for staged upgrades where the front-stage layout may evolve over time.

Key Features

• 145W RMS Power Handling: Supports substantial power from a compatible audio system.
• Plus One Glass-Fiber Woofers: Rigid glass-fiber cones and rubber surrounds support controlled output.
• Silk Dome Tweeters: 3/4-inch edge-driven tweeters extend response to 40 kHz.
• Adjustable Tweeter Level: Select 0 dB or -3 dB tweeter output.
• Three-Way Upgrade Path: Selectable crossover accommodates a compatible optional midrange.

Design & Installation

The Kappa 693CF uses glass-fiber woofer cones, hi-roll rubber surrounds, ferrite motor structures, and 3/4-inch silk dome tweeters. Its external crossovers use attached input, woofer-output, and tweeter-output leads. The crossover housing is slim and includes switches for tweeter level and two-way or three-way operation.

Verify vehicle-specific fitment before purchase, including a 220 x 147 mm mounting cutout and approximately 80.1 mm of woofer mounting depth. The package includes hardware for woofer installation plus surface, flush, and Starfish tweeter mounting options. Install the supplied crossovers between the signal source or amplifier and the separate woofer and tweeter connections, observing polarity and selecting the desired tweeter level before final panel reassembly.
