Infinity KAPPA-603CF Kappa 603CF 6-1/2" Two-way Component Speaker System

The Infinity Kappa 603CF 6-1/2" (165mm) two-way component speaker system is engineered to deliver a new standard of excellence in car audio. These speakers are designed for audiophile tastes, benefiting from a refined design, Infinity's proprietary technology, and premium materials to provide uncompromised audio quality.

The system features patented Plus One™ glass-fiber woofer cones, which are lighter and stiffer than traditional materials, offering increased low-frequency output and higher efficiency. The hi-roll rubber surrounds ensure durability and robust bass response. High-resolution 3/4" edge-driven silk dome tweeters, equipped with oversized voice coils, deliver silky smooth highs up to 40kHz with impressive thermal power handling and minimal distortion.

The Kappa 603CF includes slim, external crossovers with a push-button for 0dB or -3dB tweeter output level control, allowing for optimization based on installation location. These crossovers are also designed for 3-way upgradability, accommodating an optional 2" or 3" midrange speaker for a perfectly balanced three-way system. With ultra-high sensitivity and a 3-ohm impedance, these speakers can be powered by a factory radio or aftermarket stereo, but will achieve their best results with an outboard amplifier, safely utilizing every available watt for exceptional performance.
