Infinity built the latest Kappa speakers with improved technology and high-end materials to provide you with outstanding sound reproduction. The Kappa 63.9i 6-3/4" 3-way 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. A super-tweeter tops off the musical spectrum by broadcasting the extreme high frequencies.
The computer-optimized outboard crossover networks employ audiophile-grade components to separate highs and lows, so that the woofer and tweeters 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.
