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.

First, I want to say these are extremely good 6.5" drivers for the cost; well worth it if you have the room for them. Great bass response and mid range. Great looking product.
Secondly-- importantly-- all of the components are very large compared to their peers. If you think you may have limited space, this probably is not the kit for you. The tweeters are so large and deep, they make a hard fit. They are extremely bright and I have my tuned down -6db. The crossovers are way large. The drivers are larger than your typical 6.5"-- I'd say a true 6.75"+.

Overall, a really nice set of components for the price. Quality seems great. Mid to highs are very clear and precise, but as other reviewers mentioned, the highs (S's especially) can be a little harsh at times, even with the -6db mute button pressed on the crossover. The tweeter body's and mounting cups are rather large, which may or may not limit your mounting locations. It forced me to put mine in the door panel, which could explain some of the harshness due to poor angle. They are listed as 2 ohm impedance, but like one reviewer mentioned mine are ~3.2ohms at the speaker, and a little more when measured through the speaker wire. The crossovers are really nice... count on losing that tiny hex key though. These things shine with a little juice... it would be a great injustice to power these by the headunit or a poor quality cheap amp.

You should all be aware that this set of component speakers is the first I have ever installed, and the first that haave been installed in this car. I would rather talk about Inifinity as a brand. The Kappa series of Infinity uses quality material which translates into clear precise sound. I have a lot of tuning capability in my car ( AudioControl DQXS), but even when I hook these speakers up to my 5 Band EQ headunit you can hear the quality resonating from these speakers. If you are looking for quality over quanitity, I would suggest these speakers. The RMS rating is higher or as high as most component speaker sets in this price range. I have 150 watts RMS going to each set of woofer and tweeter. With plenty of power you can hear these speakers at their peak. Higher volumes you begin to get distortio, vibration..etc., but if you do not plan on dynamating your doors than you will get background noise like that regardless.
