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.

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.

Paired these with a Pioneer GM-D9500F and an MTX Audio Thunderform FZX3500BK12-T45 and an older Kenwood head unit and i must say it sounds better that i planned. The reason i did this project is a friend had just purchaced a 2011 Mustang GT with the 1000 watt shaker system w/ 2x 10 sub in the trunk, it reall put my stock system to shame and made songs i wasn't that fond of sound great. Now he tells me that my new system sounds better then his!

Good speakers, not much better than my factory's but a good price for a pair of infinites. Running them with a jvc avx77 in a 2k Lincoln LS, plan to install an amplifier as well, nice highs and decent lows.

Installed these speakers in my 2004 F-150 FX4, powered by the Clarion CZ500 head unit and these speakers are great. Sound quaility clear and loud. I had a Memphis Audio system previously and these are crisper and cleaner. The tweeter adjustment is a great added bonus when you're tuning the front and rear sets. The bass is nice without adding any distortion to effect the range of sounds. The speakers needed very little adjustment to fit into the factory holes. Infinity definately lives up to it's name with these.
