SSI™ (Selectable Smart Impedance): Most car audio system designs call for 2- or 4-ohm impedance. Kappa Series subwoofers put the choice in your hands. A proprietary HARMAN technology, SSI lets you reconfigure your system by simply flipping a switch.
- Aero-cooled voice coil: The Kappa Series voice coil employs a two-sided, ducted airflow design that cools the voice coil, increases power handling and improves reliability. This aero-cooling design is unique among aftermarket subwoofers.
Acoustically damped glass-fiber cone: Kappa subwoofer cones incorporate glass fibres for exceptional accuracy and detail. Inherently non-resonant, the glass fiber cones eliminate distortion so your music—and nothing but your music—comes through loud and clear.
Premium screw-down terminals: Power is the lifeblood of any subwoofer. The terminals on the Kappa subwoofers accommodate up to 8-gauge wire (8.37mm 2 cross-section), which transfers low-resistance, low-loss power to the woofer, even over long wire runs
