Infinity Kappa 62.9i
6-3/4" 2-way car speakers — for 6-1/2" and 6-3/4" openings
Our take on the Infinity Kappa 62.9i by Crutchfield's Kristen Schaub
Infinity built the latest Kappa speakers with improved technology and high-end materials to provide you with outstanding sound reproduction. The Kappa 62.9i 6-3/4" speakers feature light, but stiff woven glass-fiber woofer cones that won't flex or distort. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils produce tighter, snappier bass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.
Infinity uses the same Metal Matrix Diaphragm tweeter found in many of their popular home speakers, so you'll hear the music the way it was recorded with minimal coloration or distortion. The dome tweeters pivot, allowing you to adjust them for better stereo imaging.
The computer-optimized outboard crossover networks employ audiophile-grade components to separate highs and lows, so that the woofer and tweeter work together perfectly. Pre-wired crossovers eliminate a time-consuming step in your installation, and terminals at the end of the crossover wires screw directly to the speakers, leaving no chance for incorrect wiring.
Note: Infinity describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.
Installation Note: These Infinity speakers do not include screws or speed clips. You may be able to use the factory screws to install them, but it's always a good idea to have an assortment of self-tapping screws (5/8" to 1") and speed-clips on hand. These speakers don't use a standard 6-1/2" speaker bolt pattern you'll have to drill new screw holes in either your vehicle or the included bracket in order to mount them in 6-1/2" speaker openings.
Important Note: You should use an outboard amplifier to power these speakers.

Great mid and high frequency response. Remember these are 6.5 speakers and even with adequate power will likely not produce a significant base response. Great speaker overall. I also really like the 3db frequency option setting on the tweeter.

Plus One Woofer Cones: The Plus One speakers use cones more surface area than other speakers of the same size. This is accomplished by using a new basket design and hi-roll surround. The Plus One design offers greater bass output and a significant increase in efficiency.
Woven Glass Fiber Woofer Cones: This woven-glass-fiber material is very light and extremely stiff, minimizing cone flex. This results in very low distortion and improved clarity.
Woofer Size: These speakers are marketed as 6-1/2"; they will fit in standard 6-1/2" speaker openings, but do not use the standard 6-1/2" speaker bolt pattern. In order to install them in standard 6-1/2" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket need be used. If drilling in the car is not an option, the flange on the included metal bracket is wide enough to accommodate new holes being drilled; either in a standard 6-1/2" three hole pattern or a Ford non-symmetric four hole pattern. When using the bracket the depth becomes 2.136" and the mounting height becomes 1.024".
Edge Driven MMD Dome Tweeters: Each speaker has an Edge-driven MMD (Metal Matrix Diaphragm) dome tweeter. The benefit is increased power handling and reduced distortion at high output. This technology also allows for better integration with the mid/woofer. The tweeter has an adjustable output level, +0 dB (flat) and -3 dB.
UniPivot Tweeter: The tweeter is angled and can be rotated about 270° after installation. This allows you to direct the tweeters toward the listeners, very useful for speakers mounted low in a door.
High-Output Design: The high output 2-ohm voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4 ohm speakers). The speaker's 2.0-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected headunit or amplifier. The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 2-ohm load.
Crossovers: Kappa speakers include computer-optimized, voice-matched crossovers, using audiophile quality air core inductors and polypropylene capacitors. The crossover slope is 12 dB/octave.
Crossover Connections: Each crossover is connected to the speaker by a 6" wire. The input terminals are set screws that will accept up to 10 gauge bare wire.
- Length: 3-1/16"

- Height: 1-3/16"
Intermount III: Infinity's Intermount III mounting system allows the 62.9i speakers to fit a variety of 6-1/2" (with modification) and 6-3/4" applications. Two adapter rings are included for each speaker.
