The Plus One cone on the Kappa series provides more overall speaker-cone area than others in its class

Key Features

Plus One woofer cones

The Plus One cone on the Kappa series provides more overall speaker-cone area than others in its class. With an effective increase in cone area, the speaker radiates more air. Also, the woven glass fiber woofer cone material produces a lighter and stiffer cone. The result is a better low-frequency response and a greater ability to make those important nearly tangible musical notes that people often associate with a larger speaker size.

Woven glass fiber woofer cones

Woven glass fiber woofer cone material is both extremely stiff and very light. This minimizes cone flex while allowing the cone to react quickly which yields very low distortion, improved clarity and deep low frequency response; all Infinity trademarks.

Edge-driven MMD dome tweeters

These are not commonly used W-domes, but fully edge driven domes like those found in fine home audio loudspeakers. This much larger voice coil increases power handling and provides better sonic integration with the mid-woofer. An edge-driven tweeter also has better dispersion characteristics and allows for a lower crossover frequency than comparable tweeters of its size, which improves imaging. The result is improved vocals and clarity in music.

A wide frequency response that extends to 35kHz helps compensate for speaker placement variations in the car and human hearing deficiencies in the high-frequency spectrum above 15kHz
UniPivot tweeters

Sometimes tweeters aren’t positioned in the best locations. To compensate for this, the Kappa 62.9i coaxial speakers have an innovative feature called UniPivot. UniPivot allows you the ability to “aim” the tweeters for improved stereo imaging anywhere that they are installed. The result is more realistic, better sounding music.

Ultrahigh-frequency response (up to 35kHz)

A wide frequency response that extends to 35kHz helps compensate for speaker placement variations in the car and human hearing deficiencies in the high-frequency spectrum above 15kHz. The result is that the Infinity Kappa 62.9i coaxial speakers deliver more of the full-range frequency response that you associate with great sound.

True Four Ohm Impedance

All Kappa speakers feature two ohm voice coils. Original factory-installed speaker wiring in many cars is 18-22 gauge. This wire, and heating in the voice coil when power is applied, increase the impedance “seen” by the amplifier or head unit. The impedance of Kappa Speakers has been adjusted to compensate for this increase and provides more output than factory speakers or others in its class.

Computer-optimized, voice-matched outboard passive crossovers

The 62.9i’s are unique when compared to other traditional coaxial speakers as they feature an outboard crossover that has been voice-matched for flawless performance. In using an outboard crossover, the 62.9i is able to deliver much of the performance of a traditional component system without the need to cut or modify a vehicle for a separate tweeter. And since the crossover features only the best parts including including low-hysteresis polypropylene capacitors, low-loss air-core inductors and high-quality resistors you know you will be getting high-performance sound with incomparable clarity, detail and accuracy.

Adjustable tweeter level control

The Infinity Kappa 62.9i coaxial speakers feature a user adjustable tweeter level control. Custom tuning allows users to optimize the sound for different in-vehicle locations. Simply rotate the tweeter to add or subtract 3dB of output.

Intermount III mounting system

The included mounting adapter ring makes installation easy, allowing the same speaker to be used in different factory locations without the need to purchase additional adaptors or mounting kits.

Product Information

44 years. One purpose.

Infinity speakers have been the science of sound on the move – innovation after innovation – for over 40 years. In 1968, as our first product – a breakthrough electrostatic speaker with a servo-controlled subwoofer – became highly acclaimed, we found that perfection in the reproduction of recorded sound could be a feasible objective. The Infinity brand’s first 44 years have resulted in a continuous lineup of quality systems and technical improvements that critics have roundly praised and competitors have widely copied. Now, coming up on half a century, we still have an unwavering commitment to technology and performance.

I was hoping for more when I got these. They just didn't have the nice clear midrange and treble I had expected from an Infinity product. However, the price I paid was excellent, and the overall build quality was good. So, I opened up the external crossover. I could see some room for improvement. I'm somewhat surprised that Infinity offered such a simple crossover as they did.The factory crossover is 6 db per octave on the HF, and full range on the woofer. I modded them with a 12 db per octave crossover on the HF, and 6 db per octave on the woofer. I'll share details if anyone wants to know. The resulting sound is much clearer in the treble and midrange. Cost for the mod, about $20. With the mod, they sound like much more expensive speakers than the price I paid. So, I'm very satisfied overall.

These speakers are awesome! First let me just be clear that no matter what car you have, you HAVE TO HAVE an amplifier to run these speakers. If you don't want to put an amp in your car, then get the Infinity Reference line. I initially bought my Corolla with the Kappas in it, with no amplifier and they sounded worse than my 4Runner with Infinity Reference hooked up to a Pioneer deck with no amp. After some research and talking with professionals, they said that these speakers will blow if no amplifier is installed. They will be underpowered and therefore will sound muddy and unclean. I then bought an Alpine 300 W (75 W RMS x 4 channels) and installed it in my car. What a difference! These speakers blow my mind every time I listen to any type of music. It always sounds like I am sitting there watching the band live. Another caveat is that you need a good tune with your amplifier. If you don't, they will also sound crappy, and you can blow them if you turn your gain up on your amplifier too high. I liked these so much, I bought 4 more to put in my 4Runner and bought an Infinity Kappa 4 amp to put in it. All I can say is WOW! I love these speakers, and I don't need a subwoofer in my Corolla with the Kappas they handle bass so well. Everyone who rides in my cars compliments me on how good the sound is. I have spoken to professionals and lots of them prefer the Kappas over any other speaker, mainly because they can handle the bass.

I purchased 2 of these to replace the stock speakers in my 2014 Kia Optima Hybrid. I did not have the Infinity upgraded stereo that Kia offers. I will say that the non-Infinity stock speakers from the Kia had the smallest magnet that I have ever seen. It must have been about 2 oz. Needless to say the Infinity Kappa speakers sound SO much better!! I have seen some reviews that say they have no bass. True that they will not rattle your windows or compress your chest but they have a lot of bass for 6.5" speakers. They hit hard when needed and do a decent job on low sustained bass.

I have also read in some reviews that the Infinity speakers have harsh treble. I will admit that these speakers hit the high notes very crisply. But for me that is a very good thing. I don't turn my speakers up much past half way so the highs don't sound harsh or hurt my ears at all.. They simply sound crisp and clear and highs should.

And I have read that these 2 ohm speakers will blow your amp and/or are made cheaper and that is why Infinity does it. However as long as you don't try to push your volume to its max then your stock stereo amp will be just fine. In fact you will find that you need a lower volume setting on your system to achieve the same volume from these speakers (at least compared to stock). I have no secondary amp at all and get plenty of volume and bass.

And finally, a comparison. I originally purchased only 2 Infinity Kappas for my Optima. I put them in the front doors and they sound awesome. But I wanted to replace my rears next to hopefully give me a little extra bass. I read that the Polk Audio db series went all the way down to 35 Hz instead of the 45 Hz for these Kappas. So I bought a pair of Polks to try out.

So far so good. I am waiting on my 2nd set for the back doors. I put these in a 2013 Hyundai Veloster Turbo. The factory Dimension speakers are garbage. I had them replaced twice under warranty and they blew up again. Rather than waste another day at the dealer I figured anything was an improvement. The price was also very reasonable. The reviews on this were fairly consistent so I got them. I can only compare them to the stock speakers so the difference is 1000% better. A few things though when changing speakers on the Veloster. 1- the factory speakers are riveted in. 2- the factory speaker is also an angled spacer. 3- You need to break out the speaker and re-use the spacer part. 4- Due to the angle of the door panel the door grill may touch the bottom edge of the surround. 5- you can use your own spacers. I did not because I did not want to have deal with figuring out what was going to work.

Replaced the speakers in my 2002 Durango with Infinity. Pretty straightforward fit and sound much better. These are running off the factory amp with premium sound but having used Infinity in custom systems in the past, they would sound much better with a better quality (non OEM) amp with more power.
