4" Kappa Series 2-way Speakers • 150W Max • 50W RMS • Woven glass fiber cone woofer • Rubber surround • Edge driven MMD dome tweeter • Direct connect computer-optimized, voice-matched outboard passive crossover
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.
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.
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.

Great bang for the buck!
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.

great speakers.
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.

Great value speakers.
I've been using these speakers as midrange and tweeters in my old '87 Corolla for about two years now, and these little guys really scream! They're kinda bright/harsh at high volumes,(so if you are into that, these are the speakers for you) however, with some equalizing you may get a really good result. With correct crossover settings, these speakers also handle a great amount power without distortion. Crystal clear sound with lots of details. So, final comment: I really recommend these 4" speakers. They are a little "bright-sounding", but damn, they are pretty nice speakers as well :)

Perfection!
I used these speakers to replace my old and worn out nakamichi speakers in my Sc400. I purchased two sets of these and am glad I did! For the buck these things are quite worth the money! The only complaint I have is that they have terrible lows but that's alright as long as you have a subwoofer to provide it. Anybody that has asked me about speakers i refer them to these and will continue to do so.

Crisp, good for front speakers.
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.
