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.

Great Sound Overall, like the ability to tone down the high's using the db boost button on the tweeters. Running off head unit at the moment, crystal clear up to about 65% volume. Definitely needs an amp to see full potential, wiring up a Infinity Reference 4 chan to do that job, have high hopes for SQ out of these little coaxials. Picked these up a couple days ago, apparently was on sale because now I see the price is 30 dollars more than what I payed.
Definitely worth picking up if your not in the market for components.
And for those of you wondering about using the HU to power them since they are 2ohms, I have a kenwood x993 and it does a good job of it, headunit does not run any warmer than normal pushing these 2 ohm speakers.
Plan on adding a set of the kappa 6x9's in the next couple of weeks.

These speakers have great high's and the bass is better than expected.I installed these in the front doors of an 06 honda civic and they sound great just on the head unit power. The install was a little more time consuming than expected, as they did not just drop in, but everything worked out.

I have purchased infinity speakers for a while now. I like their design with the built-in crossover for easy installs. I originally had the infinity kappa 62.9i for the front speakers which were fine I just had to use the adapter rings that comes with the speakers to mount to the doors. My door trim was touching the rubber speaker surround and caused both to tear. So I bought these slightly bigger speakers which unfortunately did not fit right to the door frame as hoped. But with some modifications and ingenuity they fit better than the smaller infinity ones and sound just as infinitys should. Excellent!

Ive had alot of 6.5s over the years and these rank as well as the high end stuff when wired up to decent wire and amp. They are 2.6 ohm and do not sound as well on deck power and factory wire.

Love em! Could not be happier for the price I paid. These sound great without an amplifier. But when you give some power to them, dang! These things scream. Awesome lows, mids, and highs. If your looking for a factory replacement or even planning your next killer system go with these you wont be disappointed!
