Our take on the Focal K2 Power 165 KR2

by Buck Pomerantz
Focal

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

K2 Power speakers — engineered for superb sound

Side view of K2 Power speaker

At Focal, all that matters is music. Focal's sound gurus engage in intensive listening sessions as they design a new line of speakers, making it their mission to create products that deliver uncanny realism, sweeping dynamics, and breathtaking depth. During the hands-on production process, they test every model meticulously to ensure that they meet Focal's exacting standards.


Focal's "Power Hi-Fi" philosophy

The K2 Power 165 KR2 6-3/4" component speaker system bears the hallmarks of Focal's "Power Hi-Fi" philosophy. Nimble woofers made from Aramid and glass fibers demonstrate the control needed to reproduce delicate classical passages, yet they'll handle the power needed to drive your bass-heavy music with authority. The sturdy zinc-aluminum alloy baskets are non-magnetic so they won't interfere with the speaker's own electronics. And this 2-ohm system extracts maximum power from your stereo or amp so you'll get more punch from your system.


Inverted dome tweeter design

Inverted dome tweeter design

Focal's inverted dome tweeters act like little woofers, dispersing the highs in a wide pattern to create an exceptionally natural soundstage. K2 Power crossovers use hand-made components developed by Focal to deliver an ideal blend of the highs and lows for a dynamic stereo image. The 165 KR2's crossover features three levels of tweeter control, a tweeter "slope softening" selector, and two levels of midrange control so you can dial in the sound to your car's environment.

Important Note: These Focal K2 Power speakers use a low impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with virtually all factory and aftermarket stereos.

Note: Focal describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Dimensions

Woofer

K2 Cone: The woofer cone is a sandwich composite consisting of a foam core, a structural glass fiber bottom layer, and a Kevlar top layer. This combination of materials results in a rigid, light weight cone with excellent damping characteristics.

Surround: The butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Phase Plug: The bullet-shaped aluminum phase plug in the center of the woofer ensures a smooth, flat off-axis frequency response by preventing the high frequency sound waves emanating from one side of the cone from interfering with sound waves from the other side of the cone.

Zamak Basket: The woofer features a cast Zamak basket. Zamak is a rigid alloy of Zinc, Aluminum, Magnesium, and Copper. Zamak is non-magnetic.

Voice Coil: The voice coil is wound around a 1-1/4" diameter low-mass Kapton former, ensuring no coil deformation.

Tweeter

Inverted Dome Tweeter: The tweeter is an inverted Kevlar dome, producing a broad sound stage. The tweeter has a Neodymium magnet to provide a powerful magnetic field for the voice coil, while still maintaining the tweeter's compact dimensions.

Mounting Options: The tweeter can be surface or flush mounted using the included adapters. Focal recommends flush mounting, but the included angled cup allows surface mounting at one of two angles; approximately 15° and approximately 40°.

Crossover

Components: Focal uses audiophile grade polypropylene capacitors and air core inductors to ensure high definition and a dynamic sound quality.

Tweeter Level: You can adjust the output level of the tweeter on the crossover to -6 dB, -3 dB, or 0 dB.

Midrange Level: Set the midrange output to High or Flat to match their position in the car. When the mids are installed low in the door, some of the output is absorbed by the upholstery and they benefit from the High output setting.

Crossover Slopes: The crossover uses 3rd order, 18 dB per octave low-pass and high-pass filters. The crossover frequency for both is 3,800 Hz.

Wiring: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.315" wide.

Dimensions

Tweeters:

  Flush Mount Angled Surface Mount
Mounting Height 0.295" 1.236"
Depth 0.96" 0.542" (screw depth)
Frame Diameter 2.055" 1.840"
Cutout Diameter 1.828" N/A

Crossover: The crossover dimensions are:

  • Width: 4.915"
  • Height: 1.335"
  • Depth: 3.736"

Seems high quality

Written By Matt, Milwaukee, WI on Saturday, January 11, 2014
Crutchfield Customer Review (What's this?)
 
I actually ended up returning the whole system as I was not satisfied by the sound quality and performance output. Because there are so many other components and factors, I am not sure of these speakers was the major contributing factor to the failure or not. So I am not sure what "star" rating to give it. It could have been many other things. I researched and tuned the system for a full week. Even though I spent a lot of money thinking I would get an extremely great sounding audio system, It actually did not sound all that much better than the factory bose system. At least not for what I paid. The woofers were capable of lots of low bass and very bright mid bass. They did not go as loud as I thought they would before distortion however. The tweeters were very loud, I had to turn them down to the -6 setting on the crossover as they were a bit over powering.
Pros:
Seems very well built. Crutchfield's customer support is very helpful.

Worth the extra $$$ over the KR 1

Written By aztekk, Tucson, AZ on Saturday, November 26, 2011
 
If you are in the market for some Focal components, and were thinking about saving some money by purchasing the 165 KR one, stop right now.

After hearing both of these at the local shop, there is absolutely NO reason to save the extra money on the KR one, because these sound alot better. It was no contest, all it took was one switch from the 1 to the KR2 to realize that the midbass cone on the 2 is far superior (The two sets sport the exact same tweeter). It wasnt that it produced more bass, it was that the mid was far more clear, rendering voices much better than the KR 1. I was surprised, this set actually makes the 165 1 sound almost bad.

If you are fortunate enough to be able to purchase the KR 1, you can probably save up $200 more to spend on this far superior set.

Outstanding

Written By Anonymous, VA on Saturday, November 21, 2009
 
I have these installed in an 02 silverado running off a RF t-400-2 amp with a kenwood kvt-614 head unit. I was very reluctant to spend the money on these as they are very high priced. After I got them in I have no regrets. These speakers can get loud to the point of pain and not distort. I agree with previous reviews that they are bright at first if your not used to this level of sound quality but the crossovers are adjustable to your preference. Full door dynamat is a must considering what you spend on these speakers. If you want the best you got to pay for the best and these are by far the best.

The Best of the Best

Written By 2fast4thelaw, Denver on Friday, July 24, 2009
 
Hands down, these components are about as good as it gets. Everything else on the sound board sounds like its playing through a pillow in comparison. These speakers have incredible midrange clarity and tight bass punch. The only set I compared that came close was a polyglass 3-way component set. I still feel these edged out a bit. People complain that these speakers are bright. Thats because they didnt realize what they were missing. Plus after break in they tame down a little and yes they may be bright, but not harsh. You will here details in your music you never have had heard before. The build quality is very apparent looking at the crossovers and its evident that cost was no object in making these speakers but you get what you pay for and these are no exception.
