Product Description

The Kappa 60.9cs component speaker system features 6-1/2"" woofers with responsive woven glass-fiber cones that won't flex during a hard workout. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils add a little more punch to the bass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.



Infinity uses the same textile dome tweeters found in many of their popular home speakers with this Kappa system, so you'll hear the music the way it was recorded with minimal coloration or distortion. The tweeters handle down to 2,500 Hz, almost an octave below the tweeters in many systems, so you'll hear more definition and detail, no matter where you sit. Infinity includes mounting hardware to install the tweeters in custom or factory openings.



The computer-optimized outboard crossover networks employ audiophile-grade components to separate highs and lows, so that the woofer and tweeter work together perfectly. You can attenuate tweeter response by 6 dB to get the perfect sonic balance if you've mounted the tweeters in a less-than-ideal factory location.



Pre-wired crossovers eliminate a time-consuming step in your installation, and terminals at the end of the crossover wires screw directly to the Kappa woofers and tweeters, leaving no chance for incorrect wiring.

1.0 out of 5 stars E&B not an authorized Infinity dealer, Mfgr. warranty is void, August 30, 2009

This product had a tweeter stop working for me a short while into the warranty period. I called Infinity corp. and they stated that I had to make a claim through the dealer I bought the system from, in this case it was E & B Electronics. As ridiculous as this sounds I tried it. The guy that answered the phone at E&B told me there is no way they will stand behind the product I bought from them. Then the guy actually tells me "We are not even an authorized dealer, we are just a store that sells a lot of different stuff." UNBELEIVABLE!! Did you know that Amazon apparently sells (through third-party partners like E&B Electronics) grey-market electronics, for which the manufacturer will not honor the stated warranty? I would not have believed this. When Amazon customer assistance did a three way call (which amazon wisely recorded) with me quietly listening to try to resolve this with the dealer, they ranted on at the Amazon representative, and told him to not "even to try to get a word in edgewise, because I can go on like this all day", then he abruptly hung up. The Amazon representative was as shocked at this display of unprofessional treatment towards the company that directs thousands of dollars of sales to them as I was.
In closing, I would highly recommend nobody buy any Infinity product from E&B Electronics as the warranty is not valid, and you will have no recourse if anything goes wrong with your expensive purchase. Stay away from these two companies.

Simply put, I have been a home/car audio enthusiast (installer/tinkerer/builder, etc.)for many years. I have used all good brands and they all have their strengths. The strength of these Kappa components is that they are ACCURATE! In other words, their strength is that they have no weaknesses. When a speaker is accurate, you can do anything you wish to tailor it to your ears. Some say the Kappas are harsh with highs. You can attenuate highs in a multitude of ways (one way is to lessen the high frequency volume with a button on the crossover)but you CAN'T make an inferior tweeter reproduce the symbols, for example, because they are "soft." In other words, you cannot make an inaccurate, softer signal more accurate, but you can make an accurate, "harsh" tweeter sound softer and still be accurate (have all the musical ingredients reproduced)! So, overall, if the music has punch, these reproduce it. If music has extraordinary detail, these reproduce it. If your system is crap, these reproduce that, too! So if your sound from these is bad, check your deck, your amp, speaker placement, etc, and forget suspecting these speakers. GET THEM.

4.0 out of 5 stars 60.9cs Install Comments, September 26, 2010

This review is from: Infinity 609CS 270W (Peak) 6-1/2 x 6-3/4 Two-Way Component System Speakers (Pair) (Electronics)

Built a system for my 2002 Yukon XL, I know, ok call it a Suburban. Room was an issue as I wanted no loss of utility in the vehicle, I found this was a compromise. Power is everything to obtain transparent sound that does not distort at even relatively high volumes. I chose the Alpine PDX-5 for three reasons 1) it had five channels at sufficiently high wattage 2) was very small and would fit under the left rear seat and 3) gossip was that although the specs quote at loose < 1% THD it would be clean. As far as amps go, IMHO there is no such thing as too much power because you only use what the volume requires, it is that simple. The Alpine is a good amp and my selection of speakers helped the amp a bunch.

Chose two Infinity 60.9cs 2-way component systems sets with a pair in the front doors and a woofer in the rear door and its tweeter in the very back pillars. The Infinity's have a very high Sensitivity (93 db@1 watt@1meter), therefore they are very miserly when it comes to power. The rule of thumb is every 3 db increase in volume requires a doubling of wattage so they are way ahead of say a speaker with a sensitivity of say 87. They are crystal clear and indeed I hear stuff in the music I don't hear in other systems.

The tweeters come with like (5) ways to mount them and the one that I love and worked for me was a threaded cylinder that has a mating basket that fits in it.. The cylinder permits varying the depth of the mount (out or into the plane) by inserting homemade spacers and the basket allows aiming the tweeter at what looks like up to 45 degrees! The tweeters I replaced up front are now directed right up to the front passengers, very powerful stuff.

The speakers come with their associated passive crossovers. These things are clunky at best and I ended up putting a set under each rear seat. They could have been made with the corresponding components (for example the coil) being put with its driver (woofer) as an assembly which I would have liked. Regardless, they work very well as evidenced by the sound.

For the bottom end I required a very shallow 8" for my factory sub box. Among the vast number of 8" out there (is there another?), I selected the Pioneer TS-SW841D. It turns out it is a feisty little guy and provides good bass down to 60 HZ, HUG. No really that is the 5 db down point in a closed box. It is way better than some 8" in open air in many a car. What I found that was very important was setting the Alpine's high- pass to the 60.9CSs to 75 hz and the sub low-pass to 75 hz. Otherwise there is a spike of bass that will give you a headache for sure. Later I plan to go with a Stealthbox but for now the 8 sounds just fine
By the way, got a Pioneer DEH-P7200HD deck and media selection is phenomenal compared to factory. Need to use it for a while to be able to comment on usability.
