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.

Bought these for my 2011 F150. They were a massive upgrade from the stock garbage Ford put in there. I'm only running them off of the factory stereo, and they are loud and clear enough to make your ears hurt.

I purchased 4 of these for the 4 positions in my F150 std cab. I found the resulting image very muddled, and WAY too bright.
With some tuning however, the results are now very good.
The short version of my "formula" is to keep the door-mounted speakers as full range, with the tweeters set to the lower output setting on the units. The rear speakers are being used as subwoofers for the moment, crossed over at 80 hz, which I can easily set up by the Pioneer head unit I have.
The muddled imaging is Ford's problem due to speaker placement, but was underscored by the much increased presence and brightness of the Kappas. I could simply clearly hear the placement distortion issues I'd always had.
The brightness is easily controlled - I think again it's a function of what vehicle these will go into. If this was a large SUV with a much bigger internal volume, and speakers mounted low on the doors, the extra tweeter output would be welcome.
You can dial down what you have to fit, but you can't dial up what's not there. No points deduction for Infinity - this only means one can arrive at crisp clean highs and mids in about any vehicle, if one takes the effort to tune the results.
These don't have a profound low end, but that is again at least partly a Ford thing. The door and rear mounts have cutouts right by them, and also scattered near them, so you can't really get much bass from any speaker. It's like a free-air mount; the back waves cancel the front to some degree as they aren't seperated, so much of the bass is cancelled.
That said, it's ok, especially with the rears at least trying to help out.
Once they get back in stock (and one day they wil...) I will add a JL Audio CP108LG-W3v3 (8" sub-in-a-box), and a RF monoblock amp for real

Great speaker, awesome sound and easy installation. Just pay attention where you mount the crossover module because I mounted it in the wrong place and my window damaged it.
