Infinity Kappa 603CF 6.5" 2-Way Component Speakers

Infinity Kappa 603CF is a 6.5" component speaker system built for audiophile-minded car enthusiasts who want detailed highs and strong, controlled bass from a compact 2-way setup. It combines Plus One+ glass-fiber woofers with edge-driven silk-dome tweeters for extended high-frequency detail up to 40 kHz and punchy, tightly controlled low end.

• 6-1/2" Plus One+ glass-fiber woofer cone: extended surface area from edge-to-edge cone design yields deeper bass and better midbass control, while a hi-roll rubber surround maintains rigidity under high power.
• Edge-driven silk dome tweeter: delivers smoother, more open high-end with minimal distortion at high listening levels, up to the system’s top-end performance.
• 3-ohm impedance: higher sensitivity and flexible pairing with factory radios or aftermarket amplifiers, enabling strong playback across a range of head units.
• Power handling: handles up to 110W RMS (330W peak) per speaker, providing dynamic headroom for demanding music and powerful transients.
• Frequency response and sensitivity: 45 Hz – 40 kHz response with 93 dB sensitivity at 2.83V, balancing deep bass extension with efficient high-frequency reproduction.
• External crossovers with tweeter level control: premium crossovers let you dial in the balance between woofer and tweeter, and adjust tweeter level for precise imaging in your vehicle.
• Install fit and dimensions: woofer top-mount depth 2.114", cutout diameter 5.128", designed for common 6.5" component openings.
• Grilles and warranty: grilles are not included; factory grilles will be suitable. Warranty: 3 years.
• What's in the box: includes 2 woofers, 2 tweeters (each with a 6" lead attached terminated with male quick-slides), 2 external crossovers, installation hardware, and manual.

Benefits: This system is ideal for front-stage upgrades in vehicles where you want imaging with a precise high-end and strong, controlled bass without excessive power. The Plus One+ woofer design and 3-ohm impedance maximize power delivery from a range of head units or amplifiers, while the external crossovers and tweeter level adjustment let you tailor the soundstage to your car’s acoustics. The compact depth and included mounting hardware simplify installation in tight dash spaces, and the high-frequency extension reveals more detail in cymbals, vocals, and ambient cues, elevating overall sound quality in a true component configuration.
