Infinity Kappa 63XF 6.5" Coaxial Speakers

The Infinity Kappa 63XF 6.5" Coaxial Speakers deliver audiophile-grade detail in a compact, 2-way package, pairing edge-driven silk-dome tweeters with Plus One+ glass-fiber woofer technology for precise imaging and strong bass in a car environment.

• Plus One+ glass-fiber woofer cone: expands the cone edge to increase surface area for more bass output and better low-end extension while remaining responsive at higher power levels.
• Hi-roll rubber surround: supports durable, controlled cone movement for consistent mids and tight bass even at higher listening levels.
• Edge-driven silk-dome tweeter: delivers smooth high-frequency response with minimized distortion at high volume for clearer vocals and detail.
• UniPivot angled tweeter design: rotatable up to 270° so you can aim high-frequency energy toward your ears, improving stereo imaging even when doors sit low in the vehicle.
• Tweeter level control: lets you adjust brightness to taste, matching harshness or sparkle to your vehicle’s acoustics and your preferences.
• Impedance and power handling: 3-ohm impedance and 85 W RMS (255 W peak) — designed to be driven by a factory radio or aftermarket amp, with the ability to take advantage of available wattage for cleaner, more dynamic sound.
• Frequency response: 45–40,000 Hz provides deep bass foundation and extended treble, covering a broad musical range with emphasis on clarity and detail.
• Sensitivity: 93 dB at 2.83 V/1 m, indicating strong efficiency so you can achieve higher listening levels with modest amplification.
• Mounting and compatibility: brackets support installation in a variety of 6-3/4" and 6-1/2" openings, aiding fitment in common door and panel setups.
• Grilles: grilles are not included; factory grilles should be suitable for many applications.
• Top-mount depth: 2-1/8" installation depth to help plan fitment in tight door cavities.
• Warranty: 3-year warranty.
• What’s in the box: Infinity Kappa 63XF owners manual, two 2-way speakers, brackets, screws, foam gaskets, logo badges, and installation template.

Benefits: These speakers excel in a practical upgrade scenario from factory systems or mid-tier amps, delivering crisp highs with extended treble and a solid bass character thanks to the Plus One+ woofer and efficient 3-ohm design. The UniPivot tweeters enable precise imaging even when mounted down low, while the adjustable level control lets you tailor brightness to your car’s acoustics. With flexible mounting options and included installation hardware, they fit a range of 6.5" openings and install depth, making them a robust foundation for a high-fidelity, driver-friendly car audio build.
