K2 Power speakers — engineered for superb sound
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 165KRX2 6-1/2" 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 a little more punch from your system.
Inverted dome tweeter design
Focal's 2" 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 165KRX2'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.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

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 1-9/16" diameter low-mass Kapton former, ensuring no coil deformation.
Inverted Dome Tweeter: The TN53K tweeter is an Aramid fiber inverted 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. The dispersion is controlled by the twin radius wave guides to improve staging and directivity.
Mounting Options: The tweeter can be surface or flush mounted. Focal recommends flush mounting and the flush mount cup is built onto the tweeter housing. The included angled cup allows surface mounting at approximately 30°.
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 allows slope adjustment of both the low-pass and high-pass filters. The woofer can be run full range and use its natural mechanical roll off, or be crossed over with a 12 dB per octave slope. The tweeter can be crossed over with a 12 dB or 18 dB per octave slope. The crossover frequency for both is 4,700 Hz.
Wiring: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.315" wide.
