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.

Very good overall sound quality and clarity. If you listen to any kind of metal these speakers do a wonderful job of recreating the sound from the drums especially the toms. The only negative I have about these is they try to play too low. Even crossed over they still seem to play lower than they should.

I recommend this to any one that wants a good 2 ohm speaker. I have four of these running on a Rockford Fosgate T-400 and they sound great evan past the rated 75 watts RMS.

Replaced factory speakers with these, driven by a Pioneer GM-D9500F. I've had several audiophiles and musicians in my car and they want me to do the same setup for them. Truly amazing sound.

I purchased two sets (4) of these for my 2011 Kia Sorento and I have not been disappointed. I hear things in my music that I have never heard before. These speakers are the best three ways I have owned to date. I have a Crunch amp (PZA1200.4) pushing these and my stock tweets and it can blow my ear drums out if I turn it past 15 on my headunit. I will buy other infinity products as these are the best.

I have owned just about every brand of speaker and by far these are the best! Amazing highs and mids! They made my system extremely balanced.
