Product Description

Product Description
Infinity Kappa Series loudspeakers embody technological breakthroughs that make them, quite simply best in class. If you are looking for sound quality that rivals the best home audio systems, then Kappa is the ideal choice.Plus One woofer cones patent pending technology delivers a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency.Edge-driven MMD dome tweeters 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.To ensure proper imaging the 682.7cf utilizes a patented rotating tweeter. So even if the speaker is mounted down low in the door, the soundstage can be brought up and optimized for the listener's location.Woven glass fiber woofer cone material is extremely stiff, minimizing cone flex which yields very low distortion and improved clarity, an Infinity trademark.SLI high-output design. Conventional 4-ohm speakers do not leverage all of the power available from today's car audio amplifiers and high-powered head units. This topology extracts every last watt from the amplifier source, increasing overall system output and efficiency.Computer-optimized voice-matched outboard passive crossovers - Each Kappa multi-element and component system features an outboard crossover that has been voice-matched using audiophile grade air core inductors and polypropylene capacitors. The result is flawless performance with incredible detail and accuracy.Adjustable tweeter level -Each Kappa multi-element features a user adjustable tweeter level control. On the two-way models, simply rotate the tweeter to add or subtract 3dB output. On the three-way models, it is the simple push of a button right on the tweeter faceplate.

5.0 out of 5 stars A really good speaker, even if bought at full price, March 4, 2008

By	John Palmer (Seattle, WA United States) - See all my reviews (REAL NAME)

Extensive Review of the Infinity Kappa 682.7cf 6x8 2 way car speakers. I chose these speakers based on a prior experience with some in a friend's car years ago, and they were the Reference series models and sounded fantastic even then.

I ordered them through a 3rd party seller here on Amazon at considerably less than the street price on the 25th of February and they arrived later that week. I installed them that Saturday in my 1992 Ford Ranger extended cab truck, replacing the stock 6x8 speakers in the back. The month prior, I had replaced the original factory cassette head unit that still worked great, except sounded pretty bad as far as the electronics are concerned with a Panasonic CD head unit, model CQ-C1305U deck, boasting 50Wx4 amp for a total of 200W peak, with a nominal power at around 18W per channel, quite adequate for the truck and seems more than what the factory head unit put out. Immediately, I noticed a difference, just w/ the head unit, the original speakers did improve some, but still were not very clear, although the bass extended a tad as a result of the additional power going to them, the highs and mids, while still so, so, improved a bit too, making them actually passable in many respects but still sucky overall, just not as bad as before.

Now, enter the Infinity's in the back of the cab and the difference was virtually night and day different as far as clarity goes. Nice, crisp highs without being shrill for most recordings, even at moderate to high volume. The bass, while not super deep in that it won't do much beyond 40Hz, does bass very well in all other respects and is more than adequate, although a sub can add to the bass experience, but really, isn't necessary for most situations IMO.

Now when I mean bass, I mean the ENTIRE bass range, not just the boom of the mid bass or so that serves as the driving bass line, or bass beat of a given recording, especially of most Pop/R&B/Soul etc recordings. What I mean is this, how well a typical large speaker can handle the overall bass range that will include instruments such as the Bassoon, Tuba, stand-up string bass, Cello, electric bass guitar, various drums from the kick bass to kettle drums and all of the various snares/drums in a typical drum kit - all of it, including the lower registers of the organ and piano too and all of it's resonant/harmonic frequencies as well

So the prime question is, do these Infinity's measure up? Yes, quite well in fact. They can reproduce pretty much the entire bass range with ease and with clarity too - even at moderate to high volumes, something not all speakers are capable of. Now, I do run my bass setting at a +6 or a +8 since I have no loudness compensation switch on this head unit and have found it to be plenty for the setup I have. Anything higher than that will eventually damage the front stock drivers of which one is already on the raspy side and that does mar the overall sound a little, due to the lack of clarity of the fronts, which are still stock at this time but that's minimal as I mostly am getting the infinity's clean, clear sound instead, even with the fader at center, which tells me they are more loud than the stock drivers are, in large part due to their 2 Ohm impedance, instead of the typical 4 Ohm found on most car speakers. How do the highs and mids fair? Again, a very good question, they are very much improved. The highs retain their composure and almost never become glaring when driven loudly, but even then, it's I think more the fault of the recording that the speaker itself. The mids are overall smoother and less overt than I got with the old speakers, in fact, the overall clarity of the high to mid frequencies are just as clear as the bass and the extreme highs are succinct, something I was not getting before, the cymbals, high hats and such are crisp and clean, even with the tweeters left at full spectrum, rather than attenuated -3dB, which you do have the option of doing. Something I do like is that you can rotate the outer ring of the tweeters to aim them at or close to your ears so you get more of prime sweet spot of the tweeters, rather than off axis, allowing you to experience more of the speakers full range since in most cases, the speakers are in less than prime locations for good special/stereo imaging to begin with in most vehicles.

I would recommend you bring along an MP3 player or mix CD of the music you tend to listen to in the car and if it's as wide as what I listen to, it can range from vintage Rock/Pop, Soul, R&B, Blue Eyed Soul (Rascals et-al), Southern rock (Lynard,Skynard) , California Rock (Doobie Bro's) on through more current groups and artists with very compressed and loud CD's (Blues Traveler), I'd include samples of any and all of it as so much of it represents a wide array of bass information, which my Free-Form CD mix is and on it, I have Bubblegum Pop (some of them have great electric bass tracks throughout the recording) to Pop to Blues Traveler to you name it, it's probably on there and I was very impressed with the overall capabilities of the speakers to faithfully reproduce them as accurately as possible.

The installation itself was mostly a straightforward job, just the space I had to work in was cramped and the stock wiring harnesses had little slack but I did manage to get them installed and they fit perfectly where the old ones were. However, that made lashing the outboard crossovers a bit of a challenge as well, and it was not helped by zip ties that were too short, so had to lash two together to make it all work. Outside of that, the install was not too difficult and took I'd say an hour and a half or so.

Overall, I'm very pleased with the speakers and have found them quite nice and a definite upgrade for the stock speakers. If there is a downside and that is on some CD's, they may not sound as "loud" as one would think they aught to and thus think the volume has to be turned up when in fact they are "loud" to begin with, which is not good on anyone's hearing but outside of that, they are an excellent choice for speaker replacement/upgrades.

5.0 out of 5 stars Great Speakers, July 24, 2007

By	santussubs "subs" (Beaufort, SC) - See all my reviews

My first set of infinity speakers and the quality is amazing. Sound: awesome highs, I had to turn down db adjustment on the tweeters in the front door and the base is great as well. Be warned, there is are external cross-overs that come with these speakers that have to be mounted somewhere and installed. The cross-overs are relatively small but did make for extra unexpected work.
