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.

Speaker Specifications

Series
Kappa (Infinity)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Pair
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6-1/2"
Design
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Component System
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

UHF
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Woven Glass Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
270 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
90 watts
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
95 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
45 - 35000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
2-7/16"
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.

Hard as hell to beat product

March 1, 2014

The pros. Once you adjust the DB bottom to - 6 db on the tweeters these infinity kappa 60.9cs will sing sweet music from your vehicle to your ears.who sad they didn't have bass or midbass. (Haters). For the size of a 6.5 diameter woofer there's plenty mid-bass . Keep in mind I just had my speakers installed today NO break in time and they sound wonderful. I listened to focal ps-165 which sound ONLY good if all your songs are just vocal or opera. Jazz blues funk or classic rock the infinity SMOKE them. JL audio c5-650 great speakers but seriously to damm over price. Alpine sr-60c damm good speakers for the money but the infinity sound and perform better. The cons if you don't adjust the DB level on the tweeters they sound harsh.

It seems a lot of people complain about the highs coming from the tweeters. Well buy a decent head unit and the right amp ,and that problem is easily fixed. When tuned right these speakers have great drive and fantastic highs! Just make sure you buy from sonic best prices and service I've seen.

1st day impressions

January 3, 2014

I had a pair of the kappa60.9cs installed today, amp of choice jx360/2. I'm very impressed, I'm literally grinning ear to ear typing this review. As most have noted, the tweeters are bright. However, I like it bright. Not at all harsh, at least for my hearing preferences. The mid-bass preforms well and helps fill in the notes the sub can't hit. All in all I'm extremely satisfied...so far. Note** only 1 star for durability, speakers installed today.

Awesome Speakers

August 19, 2013

These speakers sound great. I made up some speaker boxes and i am using them in my boat cabin of my 28 ft. Searay. The sound out of these speakers blew my polks away. The only difficult part was wiring the tweeter and mounting the crossover in the speaker box. But well worth the extra time.

You got to allow room

March 29, 2013

I bought these for my 2010 Kia Forte Koup a week ago and installed them. This website said they would fit no problem... Big problem! The magnets on them extended so far I couldnt even roll my window down half way. But with some power tools and thinking, I was able to intall them by making my door speaker well deeper by pushing them out and fastening them to the door. So the protrude out a bit but looks plush with the car door, Wish I could upload a picture. But they sound great!!!

Infinity Kappa 60.9cs

December 30, 2012

I just bought these components because I had Infinity reference coaxials in the front of my car, I put the coaxials in the rear and these component woofers in the front. I had to cut a hole to mount the tweeter but I already had that planned the the crossover fit perfect inside my door panel. These are not amped they are just hooked up to the head unit. Since these tweeters can handle up to 35kHz, they produce VERY loud frequencies and make my ears ring for a long time without listening to a complete song. My head unit is set at Sub: 10, Bass: -2, Treble: 7. You cannot go wrong with infinity they have amazing quality and a 3 year warranty.

Better can be had

December 10, 2012

Where to begin... This is definitely one of the poorer performing component sets that I have ever owned. The tweeters are extremely bright sounding, almost to the point of having a "piercing" sound to them. Not to mention the size is a bit awkward. As well, the connection points for the tweets are very difficult to use since it requires a nearly microscopic sized alan wrench. This makes it very difficult to establish a secure connection when using anything larger than 18 gauge wire, when can be a problem when trying to maintain a fluid wiring look for your install. Onto the mids. On two separate occasions I had one of my midrange driver fail. The spider separated completely from the base of the speaker. This was not done from overpowering, or excessive heat, but the glue joints just undid themselves; in the springtime no less. Additionally, the mounting brackets that come with this set, did not fit either of my two vehicles, therefore I had to resort to making custom MDF spacers in order to make a secure mount. Really the only positive to this set is the fact that they come in a two ohm configuration. Aside from that, I can't think of anything positive to write about. I most certainly would not get another set, or recommend them. I understand that this is an entry-line offering from Infinity, yet other companies offer entry-level components at the same price point that are made of a much better quality and much more user friendly.

Kappa Compenents

June 14, 2012

I bought these about 4 months ago running off a Rockford Fosgate P400-4 amplifier. Let me start off by saying that the tweeters are huge! Seriously, do not expect to be able to fit these in factory tweeter locations without a good amount of modification (that's why I gave them 3 stars on ease of use). I ended up just cutting holes in my doors and mounting them in the swivel mounts (which are awesome for pointing them any direction you want) but the tweeters are amazing, voices sound great and I never hear any of that strong horrible "ssss" sound with S's that most tweeters do. I have them set to -6 on the crossover and they sound magnificent. I hear many tones other tweeters totally miss out on. On to the speaker, it has a very large magnet and the cone is made out of nice woven material. The speaker does go pretty deep in the door panel so make sure you measure how much depth you have to work with before you buy. The mid bass was lacking at first, but after the speaker breaks in a bit it has great mid bass. I have subwoofers so I can't comment on bass reproduction, but these keep up with my Sundown SA-12's on 2000 watts all day long. I have all Infinity speakers in my car and they sound amazing. To the people who think I'm just nuthugging Infinity, last weekend I won 1st place in Sound Quality at the Texas Showdown car show. The judge pointed specifically at these components and told me he was "very impressed" with them. All I have to say for the people that are not getting the quality sound these can produce, mess with the settings on your amplifier/head unit. Use the High Pass Filter on your deck, mess with every little detail in the "Settings" menu until it is perfect. I have my mids boosted at 500 hertz and it made such a difference from the factory settings. One last note, if you don't have an amplifier to power these, don't even bother buying them. If you're looking for components to be powered off just a head unit, look for speakers in the 25-40 watt RMS range. These will not sound good off just a head unit. Hope this review helped, I love these components. I put the Value at 4 stars because $200 is a LOT of money! But hey if you have the money and a 4 channel amp go for it!

Large, Bright Tweeters

July 13, 2011

First, I want to say these are extremely good 6.5" drivers for the cost; well worth it if you have the room for them. Great bass response and mid range. Great looking product. Secondly-- importantly-- all of the components are very large compared to their peers. If you think you may have limited space, this probably is not the kit for you. The tweeters are so large and deep, they make a hard fit. They are extremely bright and I have my tuned down -6db. The crossovers are way large. The drivers are larger than your typical 6.5"-- I'd say a true 6.75"+.

Great clarity, quality and value. Not perfect though.

June 14, 2011

Overall, a really nice set of components for the price. Quality seems great. Mid to highs are very clear and precise, but as other reviewers mentioned, the highs (S's especially) can be a little harsh at times, even with the -6db mute button pressed on the crossover. The tweeter body's and mounting cups are rather large, which may or may not limit your mounting locations. It forced me to put mine in the door panel, which could explain some of the harshness due to poor angle. They are listed as 2 ohm impedance, but like one reviewer mentioned mine are ~3.2ohms at the speaker, and a little more when measured through the speaker wire. The crossovers are really nice... count on losing that tiny hex key though. These things shine with a little juice... it would be a great injustice to power these by the headunit or a poor quality cheap amp.

First set of Components

May 23, 2011

You should all be aware that this set of component speakers is the first I have ever installed, and the first that haave been installed in this car. I would rather talk about Inifinity as a brand. The Kappa series of Infinity uses quality material which translates into clear precise sound. I have a lot of tuning capability in my car ( AudioControl DQXS), but even when I hook these speakers up to my 5 Band EQ headunit you can hear the quality resonating from these speakers. If you are looking for quality over quanitity, I would suggest these speakers. The RMS rating is higher or as high as most component speaker sets in this price range. I have 150 watts RMS going to each set of woofer and tweeter. With plenty of power you can hear these speakers at their peak. Higher volumes you begin to get distortio, vibration..etc., but if you do not plan on dynamating your doors than you will get background noise like that regardless.
