102.7W Infinity Kappa 10" Subwoofer 1 or 4 ohm

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 102.7w 10" subwoofer's impedance from 1 to 4 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. 
There's plenty of performance to go with the convenience. This Kappa subwoofer features a lightweight, powerful neodymium magnet that drives the woofer with authority while keeping the overall weight down. Infinity suspends the stiff woven glass fiber cone in a rubber surround that keeps cone movement on track. The aggressively-styled dustcap enhances the cone's rigidity, so your bass stays focused and tight when the power's cranked.
