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.

  • 6" x 8" (5" x 7") Kappa Series 2-way Speakers

    • Peak: 600 watts per pair / 300 watts each

Speaker Specifications

Series
This is the manufacturer product line of speakers.
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" x 8" (also mounts in most 5" x 7" locations)
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
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.

Metal Matrix Diaphragm
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.
300 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.
100 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".
94 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).
40 - 25000 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.
3"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
7-1/8" x 4-5/8" 
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

July 6, 2012

Ordered 2 sets for my 2011 F150, front and back doors. First, hooked them up on stock head unit with no amp, and they definitely sounded much better than the stock junk speakers. Since then, I have them hooked up to an amp running about 85watt RMS to each, and they sound even better. Had them for over a year now and no complaints.

December 13, 2011

Installed these speakers in my 2004 F-150 FX4, powered by the Clarion CZ500 head unit and these speakers are great. Sound quaility clear and loud. I had a Memphis Audio system previously and these are crisper and cleaner. The tweeter adjustment is a great added bonus when you're tuning the front and rear sets. The bass is nice without adding any distortion to effect the range of sounds. The speakers needed very little adjustment to fit into the factory holes. Infinity definately lives up to it's name with these.

Excellent speakers!

January 29, 2013

I admit I bought these from another retailer, but I wouldn't hesitate to buy from SE at all.
These speakers are great, and I love the off-axis tweeters. They really do help to bring up the soundstage if you only have speakers in the lower door panels and no dedicated tweeters up higher, as is the case in my Focus. The tweeters are a bit harsh though. I guess this is what some would call "bright" perhaps? They don't distort, they're just a bit "sharp". After a half hour of listening my ears would tire from the treble, and that's with the -3db attenuation on the tweeter. They have mellowed out over time a bit, but still a bit sharp.
The woofer looks awesome and is pretty stiff. It sounds worlds better than my previous OEM speakers and better than any of my peers' aftermarkets. They have a good bit of midbass, and are very smooth with a nice warm presence that seems to fill in the cracks of the music. I'm only driving them on 25 watts too, I'd love to see them with more power.
You may find it difficult to deal with the attached crossover. It's annoying, and just barely fit in my door while still clearing the window when rolled down. You might want to make sure you can fit it before you buy these.
Overall I'm very satisfied with these speakers, and I'm planning to buy the component set with silk tweeters for my Mazda 3. They're fantastic for the price.

I talked to a knowledgeable salesman who helped me find the right speakers to upgrade my stock speakers in my Mazda 3. They are Infinity 682.9cf speakers and they fit perfectly in the spot of the old ones just like he said they would-what a relieve not having to modify the old speaker housing. All in all it was a simple task and the sound is ten times better-yeah! Thanks Sonic!

Dial them down on the high end....

April 27, 2012

I purchased 4 of these for the 4 positions in my F150 std cab. I found the resulting image very muddled, and WAY too bright.

With some tuning however, the results are now very good.

The short version of my "formula" is to keep the door-mounted speakers as full range, with the tweeters set to the lower output setting on the units. The rear speakers are being used as subwoofers for the moment, crossed over at 80 hz, which I can easily set up by the Pioneer head unit I have.

The muddled imaging is Ford's problem due to speaker placement, but was underscored by the much increased presence and brightness of the Kappas. I could simply clearly hear the placement distortion issues I'd always had.

The brightness is easily controlled - I think again it's a function of what vehicle these will go into. If this was a large SUV with a much bigger internal volume, and speakers mounted low on the doors, the extra tweeter output would be welcome.

You can dial down what you have to fit, but you can't dial up what's not there. No points deduction for Infinity - this only means one can arrive at crisp clean highs and mids in about any vehicle, if one takes the effort to tune the results.

These don't have a profound low end, but that is again at least partly a Ford thing. The door and rear mounts have cutouts right by them, and also scattered near them, so you can't really get much bass from any speaker. It's like a free-air mount; the back waves cancel the front to some degree as they aren't seperated, so much of the bass is cancelled.

That said, it's ok, especially with the rears at least trying to help out.

Once they get back in stock (and one day they wil...) I will add a JL Audio CP108LG-W3v3 (8" sub-in-a-box), and a RF monoblock amp for real

Paired these with a Pioneer GM-D9500F and an MTX Audio Thunderform FZX3500BK12-T45 and an older Kenwood head unit and i must say it sounds better that i planned. The reason i did this project is a friend had just purchaced a 2011 Mustang GT with the 1000 watt shaker system w/ 2x 10 sub in the trunk, it reall put my stock system to shame and made songs i wasn't that fond of sound great. Now he tells me that my new system sounds better then his!

Exceeds my expectations

April 18, 2011

I bought this pair of Kappas along with a set of JBL Power Series 5x7's for my '09 Mustang. The Kappas were installed in the front doors and the JBL's were put in the back deck. I did not want to throw a sub in my car because the trunk space is more valuable to me at this time. Putting the JBL's in the back was a good compromise.

The Infinities are very accurate producing very tight mids, highs and even some decent lows. The lows are much better than my previous Infinity Reference set though they do not vibrate the seats as much as the JBL's do in back (I tested this by fading the sound between the front and rear to single out the two pairs).

Although this is not the ideal setup, it is a good low cost alternative to getting Infinities all of the way around with a four channel amp and a single channel amp + sub combo.

The head unit that I am powering these with is the JVC KD-AHD69. The 7 band EQ along with these Kappas brings out subtleties and nuances in the music I did not hear with my factory setup or even with my other system with the Infinity Reference speakers. I imagine that with an amp, I would be able to push them to even higher volumes without distortion but even with just the head unit, they sound fantastic. As always Infinity does not disappoint with producing very clean high frequencies.

Replaced the stock speakers on Ford Taurus (500) premium sound system and they sound great with the factory 330 watt amp. I now get full high ranges, decent mid-range, and bass is great. The sound is clear and undistorted with a dramatic sound improvement. Would recommend these to any 5 by 7 installation system and price point is very reasonable. Compare and listen to others and these sound the best for overall clarity of accurate sound reproduction.

This is an excellent speaker! They sound great and I love the ability to attenuate the highs. Be carefull what you power them with though. These are 2 ohm units and CANNOT be powered in the "real" world using a factory or an aftermarket head unit. These are designed to be powered by a 2 ohm stable amp only! Infinity website says otherwise but they are NOT testing "real" world conditions.

infinity kappa 682.9cf

February 2, 2009

This is a great speaker. My personal setup is two 6x8 infinities hooked up to a 440w amp, and two infinity 4 inch round dash speakers in a ranger. These speakers work great and are very crisp. They work great for country and classical music. I am personally going to put in a subwoofer to get the full body behind the music. If you are putting these in ranger, make sure to tighten down all of your panels and you should probably put sound deadening mat behind the speakers because there is alot of power with these speakers, they give a good punch.

Extremely pleased

June 30, 2014

To begin I will say that I'm not going to bore you with the technical aspect of these speakers. I have had these installed in my 1998 Ford Explorer XLT for several weeks, and have been very pleased with their performance. I listen to a wide variety of music (i.e. Metal, edm, rap, etc.), and they have handled them all very well. I have previously owned brands such as focal, boss, and pioneer. I have by far been the most pleased with these. Currently I am running these off the stock head unit (as I have failed to install my new kenwood stereo yet), with no amplifier. I have seen many reviews complaining about the external crossover (the large black box in the photos) being a hassle to arrange. I did not experience this issue. However, if you have these professionally installed then it should not be an issue. My advice is to Velcro it to the inside of your door frame, should you decide to do a self install, and just let it rest inside the speaker mount if yours is built in (as mine is). When I unboxed them after removing my door panel and factory speakers the original plug was a bit of a surprise. However, if you cut the plug off and strip the wires slightly, the wires install quite nicely into the crossover. All in all the speakers were easy to install, perform well, and fit nicely into both 6x8 and 5x7 mounts.

good speakers

July 15, 2012

These speakers are clean and loud hooked up to a Kenwood KDC-HD548U. I have them installed in an '06 Ford Crown Vic and they are loud, but not very much bass even though I have XTC 5" x 7" Foam Speaker Baffles installed behind the speakers.

If you're not worried about bass because you have subs to add to the set up, then these speakers will do just fine for ya. I would recommend using an amp to power these speakers, especially if you're running 500W RMS or more in your subs!

The best speakers ever

December 28, 2010

This speakers are fantastic, the quality of this speakers are incredible. The clarity of the sound is by far the best for this price range. Bass response is also impressive for the size of the speakers.
This infinity speakers are well worth the money and it will not disappoint at all.

INFINITY KAPPA 682.9CF

November 1, 2010

Infinity Kappa speakers are great speakers, with a great price and great sound. they fit perfectly in my 92 mustang 5.0 convertible feature/summer/special edition. i am powering them with about 100/110 watts rms of kicker power and they have held up without a hiccup. great clarity and midrange. they are only 5x7/6x8 speakers so they down drop down too low in frequincey but with a sub to back them up they sound killer. i run infinity all around and they sound great. i would recomend these to anyone.

Great sound..... low price

July 19, 2010

I have a pair of Infinity Kappa 682.9cf in the rear of an '02 mustang and a pair of Infinity components(6830cs) in the front running off of a JL Audio 300/4 and they sound amazing. I would recommend these speakers to anyone who wants clean and brilliant highs. The only thing about these speakers that could be viewed as negative is they are not good with producing any bass, but I didn't get them for bass. I only wanted what they give me now, great sounding highs!

Well it took me a few weeks to find everything for my system. I have these amazing speakers in my front doors and rear deck. I have them hooked up to the MB Quart DSC 450 which puts out every ounce of power i will need for them. I did however blow the one speaker but it was due in part to water getting in the door and freezing between the magnet and the woofer cage which will crack at a certain tone. Everyone absolutely loves them. They have amazing highs and are incredibly great speakers. I recommend them to everyone.

i highly recommend these speakers the sound imaging is excellent and the highs are clean and crisp i am powering these with 100 watts rms per speaker and i have the low pass set at 100hz the only way to get better sound would be to go with full components but that wasnt an option in my application. the speakers these replaced were boston pro series and they couldnt even hold a candle to the sound and performance of these speakers.

High quality, very nice sounding speakers, for a great price. I have owned these for about 8 months now, and these can handle everything I throw at them from metal, rap, top 40, techno, to "unplugged" acoustic tracks. Even at extremely loud volume levels, they never fold under pressure.

These are great speakers!

low price high performance

October 13, 2014

For the relative low price these things jam very good bass(FOR A 5/7)or speaker of this size,mids and highs are great as to be expected plus swiveling tweeter helps.II've had these at 100W rms for about four years now at high volume every day with no issues if they don't sound good to you it's your amp set-up or not tuned properly don't send 40htz to mid speakers.Use them for what they are designed to do and you will be happy happy happy!I would put these in same league as JLs and I love my 13W6' s it also adds function that they are 2ohms but don't putem on a head unit!
GET THESE paying more would be a waste of money you could put towards something else like proper wiring etc.

Good punch

September 12, 2012

These speakers fit snuggly in my Mazda 6 2006 hatchback. I hooked these up with a 500 watt 4-channel amp which in turn is connected through the speaker level inputs to the stock head unit. It must be said that the sound quality from the stock non-bose head unit is extremely poor.
The speakers are nevertheless very responsive, crisp and punchy and they stay that way at any volume. Also the ability to rotate the tweeter proved to be a very useful feature. I'm sure that with a proper head unit these speakers would really shine.

September 6, 2012

These speakers have great sound quality for the mid to high range and have high power handling. Another plus is that they run at a 2-ohm load so you can buy a smaller 4-channel amp and run each channel at a 2-ohm load utilizing the amps full power. I can turn up the radio and amp without any distortion. These are the second pair of Infinity Kappas I own and both are currently in use. I highly recommend these speakers if using a sub(s) for the lows and bass.

These speakers are absolutely amazing! The fact that they are 2 ohm impedance should not make anyone hesitant to purchase! You get more out of your setup with a lower impedance, and by the time it travels through your factory wires you will have close to 4 ohms anyways. A must have for Ford owners since these fit!

These speakers are loud! I have them wired with a kicker 350.4 giving them 90 watts rms each and they destroy! Along with my 2 kicker cvr's they create a perfect sound system with incredible highs and mids followed by bass from my subs. Even along by themselves they produce great bass. I would recommend them to anyone who wants loud music.

Bass-y replacement speakers.

May 9, 2011

These speakers were purchased to replace a front/back set of speakers in a 99 F-250 King Cab. The speakers are being driven by a JVC KD-R810 receiver.

http://www.sonicelectronix.com/item_21996_JVC-KD-R810.html

The truck is like most trucks, noisy and hard on sound quality. I find these speakers to be "very" bass-y. Being bass-y is both good and bad as it's hard to find a balance between sound enhancing bass and sound distorting bass; overriding the treble.

I find the highs to be clean but the equalizer has to be carefully set so the bass-y nature of the speakers doesn't overwhelm the treble as I have old man ears (I'm 59) and typically, old men lose the highs in their hearing so the highs have to be boosted via the equalizer to compensate for this natural hearing loss.

Overall, I find these to be pricey but with a sensitivity of 94db, a response range of 40Hz - 25,000Hz, an impedance of only 2 Ohms with an adjustable tweeter, I find these speakers to be well designed and very efficient so as to assure you'll get the most out typically underpowered, in-dash receivers like the one I have.

A word to the wise, these are "STIFF" speakers to they will take some time to break-in and become flexible or responsive to the signal you're going be feeding them. You need to give them a hundred hours or so of play time before they'll loosen up and come into their own. Also, I like how well they're designed to deal with the affects of door water that typically leaks into the doorway.

Hope the above helps.

April 16, 2010

These are some good sounding speakers, quality construction for the most part. I bought 4 for my 95 T-Bird, and although I am very pleased with the sound, I do believe I'm starting to hear a bad buzz in the front right. I haven't checked to see if it's blown or has some separation or something, but it's not sounding good. I don't play my music too incredibly loud, and the bass isn't too bad. So if this isn't something other than a damaged speaker, then i am very displeased with the quality of these speakers.

these speakers sound great.. i have them in the doors of my ranger and all my mirrors shake..ive had like 4 people ask me if i have subs behind my seat, and i dont.. i have sonys in the back and im getting rid of them and buying two more of these to replace them very soon. they are great speakers and well worth your money. i dont even have an amp pushing them. my only complaint is that it was a little tricky hooking up the wires to the crossovers. but it was worth the extra 10 min. trying to get them in good and tight. and by the way, on certain rap song, the tweeters do screech some, but its not noticeable 99% of the time.

Audiophile quality for entry level price.

February 26, 2014

So far the 6*8 coaxial speakers sound great. I purchased these to go along with my front 6*8 component set in my ford focus. These are a great addition. One noticeable problem is that the tweeter was loose on one of the speakers and the only way to tighten the screw is to remove the sicker voiding the warranty. This series of infinity kappa's have very limited low end anything 80hz and below is quiet. If you adjust the bass higher on an equalizer the mids become muddy. If you plan on adding these to your car for more bass don't! You'll definitely need a sub. The quality and power handling of these is quite good but they are hungry. Factory radio power is not enough to get true definition. I have my front components currently hooked up to a 45 watt amp they sound crystal clear up until distortion. My rear coaxial are being powered by the an aftermarket pioneer head unit and they just can't keep up. I recommend you purchase an amp with these speakers.

I bought two pair of these speakers for my wife's Mustang. They fit great and sound amazing. I was surprised by the projection of the highs, and the clarity of the highs and mids. I've turned the HP filter off and they can handle 65 watts full range no problem, I tend to keep the HP on about 100hz though. I've got a Boston Acoustics GT-50 powering the speakers and sub (MTX thunderform) and it's the cleanest system I've ever put together(well until I got done with my Accord that is). I highly recommend these Infinity speakers, and might replace the Polks in my truck with them.
