Infinity KAPPA-800W Kappa 8 Inch Subwoofer with SSI (Selectable Smart Impedance)

Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition , delivering increased low-frequency output and higher efficiency.
Edge-driven textile dome tweeters - These are not commonly used W-domes, but edge-driven textile dome speakers that will deliver broader and smoother high frequency response.
High output 2.5 ohm ohm architecture with low impedance voice coils enables the speaker to extract every watt from the amplifier and deliver peak power with ease.
Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time.
Infinity is in the business of designing reference quality speakers, and Kappa car audio speakers are no exception.
KAPPA 800W 8" Selectable Impedance (2 or 4 ohms) SubwooferLooking 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. Infinity's proprietary aero-cooling design keeps the voice coil cool while optimizing power handling and long-term 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.Features: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 coilThe 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 coneKappa subwoofer cones incorporate glass-fibers for exceptional accuracy and detail. Inherently non-resonant the glass-fiber cones eliminates distortion so your music-and nothing but your music-comes through loud and clear.Premium screw-down terminalsPower 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.What's in the Box:One KAPPA 800W subwooferFoam mounting gasketMounting hardwareOwner's manualSpecifica
