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.

These are great mid range speakers with one of the cleanest sounds that I have heard in a long time! The lows are typical of small speakers, but the mids and highs more than make up for it even if you don't run an amp to it.

Sounds a million times better than my stock Porsche 996 set up and I only had to do a little bit of modification.

i have a pair of these hooked up to a crunch p900.4 and they sound great. i have them set up so they have the high pass filter and they sound crystal clear. i tried letting them bump a little by switching them to no filter but they couldn't handle much. i didn't really expect much out of 4 1/2 in. speaker anyway. overall, if your looking for a decently priced speaker to fill in the highs and mids in your system, you won't be disappointed with these.

I used these to replace factory 4 inch rounds for my front speakers and paired with Infinity 462.9cfp for the rear. They sound nice for radio, and mellow songs. However, they get overworked and bottom out while listening to pop, hip hop, and country with a lot of deep notes. Would propbably be very nice if paired with larger speakers for the lows.

Used them in my jeep wrangler and then made a custom home speaker system with them. Great for little speaker installations.
