Looking for a more moving audio experience? Take Infinity car audio for a ride. Innovative materials and breakthrough engineering have always put Infinity products out in front of the competition. So expect extreme output from Kappa subs, but be prepared for accuracy and detail that may 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 longterm reliability. And, the acoustically damped glass-fiber cones have been engineered to minimize distortion and unwanted artifacts. More performance. More flexibility. You get both when you step up to a Kappa subwoofer.
