Kappa 83WDSSI

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.

Awesome subwoofer.

For an 8in sub this thang bangs. Love it. And the small size fits in my little veloster hatch without taking all the space. Pair up with ct sounds box it hits. Had a buddy tell my it hits harder than his 12in.
