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.

Great Sound and Great Value

These speakers have great high's and the bass is better than expected.I installed these in the front doors of an 06 honda civic and they sound great just on the head unit power. The install was a little more time consuming than expected, as they did not just drop in, but everything worked out.

Very Nice

The speakers are clean and clear. These are a far cry from the oem speakers! They can hit high and they can hit low. The only issue I've noticed is when it is trying to hit low and mid at the same time the mid hits and the low gets muddied. I recommend buying with the infinity sub to keep the lows off the woofer. Also they look very nice and have pods for attaching wires making them super easy to hook up.

Great sound

I have four of them in the doors of a pathfinder,and they are just now starting to break in only after a few months.they sound great even with just a head unit. Eventually I plan to install a four channel amp, because I was told that more power would make them sound even better.

excellent

Good range with crisp highs and decent lows, bass frequency is better than most 6.5" drivers. I give them a 9.1 out of 10 max.

Kappa 652.9i speakers

Great Sound

Great Sound Overall, like the ability to tone down the high's using the db boost button on the tweeters. Running off head unit at the moment, crystal clear up to about 65% volume. Definitely needs an amp to see full potential, wiring up a Infinity Reference 4 chan to do that job, have high hopes for SQ out of these little coaxials. Picked these up a couple days ago, apparently was on sale because now I see the price is 30 dollars more than what I payed.
Definitely worth picking up if your not in the market for components.
And for those of you wondering about using the HU to power them since they are 2ohms, I have a kenwood x993 and it does a good job of it, headunit does not run any warmer than normal pushing these 2 ohm speakers.
Plan on adding a set of the kappa 6x9's in the next couple of weeks.

Not a bad speaker but no base whatsoever

I would recommend this speakers for its quality and highs, but if you are looking to have some bass as well then this is not the speaker you want. I installed them to replace my bose speakers after one of them blew out after 10 years of use and had to take them back out because the bass was way too low. I had read that this was the case with these speakers on other reviews but didnt think it would be as bad as it was with the bass. Anyway the speakers are of excellent quality if you are looking for crisp, clean highs.

Don't buy

I don't recommend because it sounds great at first but after 2 weeks, all the cables are getting poopy.
All the plugs in the speakers come from one spot and they are all attached to each other. I installed them without problems but after 2 weeks, no more sounds, i took a look and all the plugs were scratched and there was no way I could repair it.

Greater upgrade for the dodge ram, big bass

I am glad that I got these speakers for my friends truck. He had to discard the old infinity speakers that were an older model and decided to fail. The newer infinity speakers I would recommend because all Infinity products have stepped up with their equipment.
