Infinity Kappa 123WDSSI Kappa Series 12" 500W RMS Subwoofer

About: Infinity Kappa 123WDSSI Kappa Series 12" 500W RMS Subwoofer

Take Infinity car audio for a ride. Innovative materials and breakthrough engineering have always placed Infinity products in front of the competition. You can expect extreme output from Kappa subs, so be prepared for accuracy and detail that will simply blow you away. The Kappa Series subwoofers feature SSI™ (Selectable Smart Impedance), a HARMAN-exclusive impedance selector that lets you choose a 2- or 4-ohm impedance at the flip of a switch. Our proprietary aero-cooling design keeps the voice coil cool while optimizing power handling and long-term reliability. Finally, the acoustically damped glass-fiber cones have been engineered to minimize distortion and unwanted artifacts. More performance and flexibility: you get both when you step up to an Infinity Kappa subwoofer.

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.

Oversized voice coil

Kappa subwoofer cones incorporate glass fibers 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 integrated push terminals

Power is the lifeblood of any subwoofer. The terminals on the Kappa subwoofers accommodate up to 8-guage wire (8.37mm 2 cross section), which transfers low resistance, low-loss power to the woofer, even over long wire runs.
