Infinity Kappa Perfect 12.1 Subwoofer
The Infinity Kappa Perfect 12.1 12″ subwoofer joins together a rugged aluminum cone and high-roll butyl-rubber surround to produce impressive bass all the way down to 18 Hz. The ultra-rigid woofer cone won’t distort (even when you push it to the max), but it’s light and responsive for remarkably high sensitivity. That means it’ll squeeze the most volume out of the power you feed it.The massive cast-aluminum basket and the pole-piece are vented, so the 4-layer voice coil stays cool when the music gets hot. Infinity subjects these subs to the most intensive testing in the industry — 100 grueling hours of performance at their full RMS rating (350 watts).
High performance and cutting-edge technology have always distinguished Infinity Kappa subwoofers, and now they’ve set a new standard for versatility and convenience.You can change the Kappa 124.7w 12″ subwoofer’s impedance from 2 to 8 ohms with the simple flip of a switch. This versatility means the Kappa will always fit into your system plans, whether you’re using a single sub or setting up a multiple sub system. A single set of speaker terminals eliminates confusing dual voice coil wiring connections and configurations.
