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.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

5 1/4" sound good, but I think I would buy something else if I could do it again. Not having a speaker with a dust cap in a SUV is proving to be a bad idea.

They sound good, but as I only got the 5 1/4" ones I can't really comment on loudness as the 5 1/4's seem pretty weak compared to anything larger. I have 4 of them in my 2010 Toyota Rav4 and wish I would have gone with at least 6 1/2" speakers.

I thought I was very careful with cleanliness and handling, but I had one speaker that acted up after installation and had to purchase another pair to replace it (It had a crackle). The design is neat with the pivotable tweeter, but it leaves the coil vulnerable to damage from sand and other dirt that would normally be kept out by a dust cap on a conventional speaker. I can't say I'd suggest this design of speaker for a SUV or pickup that will see any dirt. Overall I would not buy these again for my application.

Awesome speakers, couldn't be happier

I could not be happier with the sound of these speakers. Pristine, crystal clear sound, with a warmth that makes it sound like you are sitting in the same room as the artist you are listening to while they perofrm their song. Love them.

So far so good !!

I installed four of these speakers in my truck and they sound great !! I purchased these because I replaced the Infinity Kappa speakers that I installed 15 years ago. Need I say more... It's a great product for a reasonable price.

INFINITY KAPPA 52.9I

I've been a stereo installer for over 10 years and Infinity speakers are what I use the most because of their clarity and ability to handle lots of power. These are some of the most crisp speakers on the market and a great buy on from this site. I'm getting ready to customize three more Harley's and they will all have INFINITY KAPPA products from front to back. I give it a 4 overall because I would like to see them up the RMS watts.

Infinity Kappa 52.9

I would recommend these to anyone. I loved the highs coupled with the nice mids. definitely recommend hooking it up through amp though. make sure the receiver is of high quality it will effect output of speakers more than anything. overall very good speakers with good sound quality.
