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.

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.

Good highs. Looks great. More bass than you would expect with a shallow design. Shallow design makes it easier to mount and it also comes with nice mounting options.

Great sound quality, great price. Only problem was that the magnet was too big for my doors. I drive a 96 Mercury Tracer and in the front doors there is a brace that partially impedes on the speaker slot, had to cut some plastic and metal and drill a few new holes, but all around worth it!

I bought 2 pairs of these speakers too install in my 2000 Jetta as my first upgraded sound system. It was super easy and fast considering i did it myself. They sound FANTASTIC, better than my friends 50,000$ Audi. Unfortunately the front door speaker blew the first day. But it was my fault because I had the music way too loud. But i just called Harman and they replaced it quickly and without question. HIGHLY recommended as upgrade.
However if you want to get the best out of these speakers you will need an amp. I just installed an infinity 4 channel amp and the difference is astronomical. Buy these.

Very good speakers for the price, I dare say best, but what do you expect from Infinity/Harmon-Kardon. The crossover gets kinda difficult to manage, but at the same time makes things easier. I think I ended up either ziptieing it or sticking it down with dynamat so it wouldn't bang arround. A flaw with my system installation means sometimes when I start my car the radio turns on at full volume, and will make you jump out of your skin (think James Brown). Using the Infinty Kappa Five with the amps crossover at 320 high pass. I think if I can pad the door panels or fur them out from the speakers, then I can set it to an 80 High pass and really make my molecules move! In the doors of my 2002 Monte Carlo SS. I belive the max excursion may be too much for the mounting space and that could be the cause of the bass distortion (either that or the panel needs reinforcement). There was also a mounting spot for a tweeter in the factory door speaker mount, kinda wish I peeled the panel off before making my purchase. I'd rather have components than #-way speakers. I went for the three ways rather than the 2ways and I think it was worth it. High value for dollar.

This is a wonderful speaker. I currently have a pair mounted in the doors of my 08 Tundra powered by a Soundstream Tarantula 4-channel amp. The highs are very clean and detailed. The bass is good, however I would recommend a sub for lower frequencies. Infinity did a good job with this one. I highly recommend them!!!!
