About the Infinity Kappa 693.9i
Infinity built the latest Kappa speakers with improved technology and high-end materials to provide you with outstanding sound reproduction. The Kappa 693.9i 6"x9" 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 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.
Important Note: You should use an outboard amplifier to power these speakers.
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.

Features
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.
Edge Driven MMD Dome Midrange: Each speaker has an Edge-driven MMD (Metal Matrix Diaphragm) dome midrange. The benefit is increased power handling and reduced distortion at high output. This technology also allows for better integration with the woofer.
UHF Tweeter: Ultra-wideband UHF soft-dome tweeters are used to ensure response to 30kHz. The tweeter has an adjustable output level, +0 dB (flat) and -3 dB.
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.
Crossover Dimensions:
- Length: 3-1/16"
- Width: 1-1/4"
- Height: 1-3/16"

Great speaker, plenty of bass, again similar to other Infinity speakers I can't tell a difference with the tweeter selector switch, but was not a big deal since I had plenty of adjustment matching these 6x9s with the 475a 4 channel.
