The Infinity Kappa 603CF represents the ultimate 2-way component speaker system engineered for car audio enthusiasts seeking reference-grade vocal accuracy and dynamic impact. Powered by HARMAN’s iconic audio engineering, this 6.5-inch speaker system combines patented Plus One+ glass-fiber woofer cones and edge-driven silk dome tweeters to create an expansive, high-resolution soundstage across your vehicle’s dashboard.

• Hi-Res Audio Certified Performance:

  Certified to reproduce frequencies up to 40,000 Hz, bringing out delicate vocal breath, acoustic instrument overtones, and master-studio details.

• Patented Plus One+ Glass-Fiber Woofer Cone:

  Extends the cone surface area beyond conventional 6.5-inch speakers, delivering stronger low-end output, higher efficiency, and tighter mid-bass control.

• Edge-Driven Silk Dome Tweeters:

  Utilizes soft silk domes driven from the outer edge to produce wide high-frequency dispersion without harsh treble spikes or sibilance.

• High-Efficiency 3-Ohm Low-Impedance Design:

  Optically matches factory wiring and aftermarket amplifiers to extract extra power output safely while delivering an exceptional 93 dB sensitivity rating.

• 3-Way Expandable Passive Crossover Networks:

  Compact external crossover modules equipped with push-button tweeter level adjustment (0dB / -3dB) and built-in selection to integrate optional Kappa midrange drivers.

• High Power Handling Capability (110W RMS / 330W Peak):

  Built to handle heavy power continuous load effortlessly, maintaining pristine clarity even during high-volume dynamic passages.

HIGH-RESOLUTION AUDIO (HI-RES) PERFORMANCE
