Infinity Kappa 683XF 6"x8" / 5"x7" Coaxial Speakers

Infinity Kappa 683XF 6"x8" / 5"x7" Coaxial Speakers are built for audiophile tastes, delivering refined, high-fidelity sound in a compact 2-way coaxial package. Designed for car audio enthusiasts who want precise imaging, extended high-frequency detail, and robust bass from a relatively shallow install.

• Edge-driven silk dome tweeters: deliver a smoother, more open high-frequency response with less distortion at high volume, enhancing cymbals and detail without harshness.
• UniPivot angled tweeter design: rotatable up to 270° to aim highs toward your ears, improving stereo imaging even when the speakers sit low in the doors.
• Tweeter level control: lets you adjust brightness to match your vehicle’s acoustics and personal taste.
• Plus One+ glass-fiber woofer cone: maintains cone shape under high power for tighter, more defined bass; glass fiber is lighter, enabling solid performance without excessive amplifier power.
• Hi-roll rubber surround: provides durable, controlled excursion for clean bass response and reduced distortion on demanding tracks.
• 3-ohm impedance: low-impedance design facilitates efficient power transfer from factory radios or aftermarket amps, helping you get more volume with less effort.
• Frequency response: 40–40,000 Hz gives extended highs and solid lows for a comprehensive musical range.
• Sensitivity: 93 dB at 2.83 V, indicating strong output for typical head units and the potential for higher volume with an amp.
• Power handling: supports up to 100 Watts RMS (300 Watts peak) per speaker, allowing solid output with a capable amplifier while maintaining control of the woofer cone.
• Top-mount depth: 2-5/16" fits a variety of dash and door cavities, helping with installation flexibility.
• Grilles not included; factory grilles should be suitable for most applications.
• Warranty: 3 years from purchase, reflecting confidence in build quality and longevity.
• What’s in the box: Infinity Kappa 683XF owner’s manual; two 2-way speakers; bottom mount adapter rings; screws; speed clips; adhesive foam gaskets; Infinity logo badges; installation template/manual.

In a real-world build, the 683XF replaces 6x8" or 5"x7" factory coaxials to deliver expanded high-frequency detail and a more tangible bass presence. The UniPivot tweeter enables precise imaging when mounting depth is limited, while the Plus One+ woofer increases cone area for fuller low end without requiring excessive amplification. Its 3-ohm impedance and 93 dB sensitivity pair well with factory radios, and you can unlock even more performance by powering them with a dedicated amplifier. The included installation hardware and template simplify mounting, and the absence of grilles is accommodated by many factory setups, with the option to use aftermarket grilles if desired. The 3-year warranty provides assurance for long-term enjoyment of your upgraded audio system.
