Infinity Kappa 63XF (KAPPA63XF) 6.5” 85W RMS | 255W Max 2-Way Kappa Series Coaxial Car Speakers (Pair)

Infinity Kappa 63XF 6-1/2" 2-Way Car Audio Speakers

Experience a new standard of in-car audio excellence with the Infinity Kappa 63XF 6-1/2" 2-way car speakers. Designed to replace factory speakers and bring your music to life, these premium coaxial speakers feature Infinity's patented Plus One™ glass fiber woofer cones. This advanced cone material is significantly lighter and stiffer than traditional materials, delivering punchy, high-output bass and a highly efficient midrange response. Paired with a robust hi-roll rubber surround, the woofer provides incredible cone excursion and durability, ensuring tight, distortion-free low-end performance even when pushed to high volume levels.

The high frequencies are meticulously handled by 3/4-inch edge-driven silk dome tweeters equipped with oversized voice coils, capable of delivering ultra-high-resolution, soaring highs up to an impressive 40kHz. For precise soundstage tuning, the Kappa 63XF features a UniPivot angled tweeter design that can be rotated after installation to direct the sound directly toward the listener, combined with a convenient push-button tweeter attenuation switch (0dB or -3dB). Operating at a true 3-ohm impedance, these speakers are engineered to safely extract every available watt of power from standard factory head units as well as high-power aftermarket amplifiers, resulting in an exceptionally dynamic and crystal-clear listening experience.

Key Features & Specifications

• Speaker Size: 6-1/2" (165mm) 2-way coaxial car speakers. Includes multi-hole adapter brackets allowing installation in a variety of 6-1/2" and 6-3/4" factory openings.
• Power Handling: Conservatively rated to handle 85 Watts RMS and up to 255 Watts Peak power.
• Plus One™ Technology: Proprietary glass fiber woofer cone design provides a larger radiating surface area than competing speakers of the same size, maximizing bass output and overall efficiency.
• High-Resolution Tweeters: 3/4" edge-driven silk dome tweeters deliver smooth, fatigue-free high frequencies and an expanded frequency response of 45 Hz up to 40,000 Hz.
• UniPivot Design: The angled tweeter can be rotated up to 270 degrees after mounting to perfectly aim the high frequencies toward the listener's ears, effectively elevating the soundstage on low-mounted door speakers.
• Adjustable Output: A built-in push-button switch on the tweeter allows you to easily adjust the high-frequency output level between 0dB (flat) and -3dB to compensate for speaker placement and interior acoustics.
• 3-Ohm Impedance: High-sensitivity (93 dB @ 2.83V) 3-ohm voice coil safely draws more power from factory wiring or aftermarket amplifiers compared to standard 4-ohm speakers.
• System Upgradability: The built-in crossover network is uniquely designed to easily accommodate the addition of an optional 2-inch or 3-inch Kappa midrange speaker (sold separately) to upgrade your setup to a true 3-way system.
