Kappa: The Essence of Infinity
This Infinity Kappa 682.9cf is the essence and trademark of Infinity car audio. With all the high-end engineering and technology that goes into each Kappa speaker, you will sure that you are receiving only the highest quality components. Made with a woven glass fiber woofer cone, which contributes to low cone flex, low distortion, and enhanced acoustic clarity. Due to the increased power handling of the Kappa series, the Kappa 682.9cf feature edge-driven MMD dome tweeters that allow for a seamless sonic integration between the tweeter and the mid-woofer. Using the latest in loudspeaker engineering, each of the crossovers has computer optimized voice-matched outboard passive crossovers for flawless performance.
Unipivot: Staging Made Easy
The Infinity 682.9cf features a patented Unipivot tweeter design that ensures proper imaging when the speakers are installed. With the tweeter capable of being moved, it is positional and rotational even after the final screw secures the speaker in the door. Since most speakers are installed low in the door, the Unipivot design brings the soundstage up to the listener for more accurate and enjoyable experience. Each of the Kappa coaxial speakers, such as the Infinity Kappa 682.9cf feature adjustable tweeter level control. This switch will adjust the tweeters output by 3 dB. That simple tuning can make all the difference in your system and it ensures that your Kappa speakers will deliver exactly the sound that you are looking for.
True Four Ohm Technology
The engineers at Infinity have developed a speaker that works for all applications. The True Four Ohm Technology used in these speakers make it perfect for running directly of a headunit or with an aftermarket headunit and amplifier. All of the speakers in the Infinity Reference line feature a 2 ohm voice coil. However, when you factor in the small OEM speaker wire of most vehicles and the heating in the voice coil during use, the impedance actually seen by the amplifier will increase. Infinity has adjusted the speaker to be safely connected to any headunit.

Running these simply off my Kenwood KIV-701 headunit and they are clean and crisp sound, not much bass goes through these so my 12" sub really made it complete. Sonic has the best pricing and would highly recommend these speakers for the price as well as the rest of their low priced products.

I used these to replace factory 4 inch rounds for rear speaker pods. they sound nice for radio, and mellow songs. However, they get overworked and bottom out while listening to pop, hip hop, and country with a lot of deep notes. Would propbably be very nice if paired with larger speakers for the lows.
