K2 Power speakers — engineered for superb sound
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 165 KRX3 6-3/4" component speaker system bears the hallmarks of Focal's "Power Hi-Fi" philosophy. The nimble 6-3/4" woofer, made from Aramid and glass fibers, demonstrates the control needed to reproduce delicate classical passages, yet it'll handle the power needed to drive your bass-heavy music with authority. The sturdy zinc-aluminum alloy basket is non-magnetic so it won't interfere with the speaker's own electronics.
3-way design
Focal's 2" inverted dome tweeter acts like a little woofer, dispersing the highs in a wide pattern to create an exceptionally natural soundstage. An additional 3" speaker, made from the same composite that's used in the woofer, provides the system with smooth midrange frequencies. An aluminum phase plug improves midrange dispersion so you'll hear clean, up-front vocals. Focal includes a pair of surface-mount pods that allow you to install the midrange driver and tweeter side by side.
High-quality crossover network
The K2 Power crossover uses hand-made components developed by Focal to deliver an ideal blend of the highs, mids, and lows for a dynamic stereo image. You'll find 162 possible combinations of tweeter, midrange, and woofer settings so you can fine tune the sound to your car's environment.
Important Note: Focal strongly recommends using a 4-channel amplifier to drive the 165KRX3 component system — two channels for the woofers and two channels to run the mids and highs. The 165KRX3 crossover can be set up to use a 2-channel amplifier, but it would present a load of less than one ohm per channel which most amps cannot handle safely.
Note: This component speaker set consists of a separate woofer, midrange speaker, and tweeter. Our Car Selector checks to make sure the woofer will fit in your factory location. You'll have to custom install the midrange and tweeter.
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.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

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.
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.
Midrange
K2 Cone: The midrange 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.
Zamak Basket: The midrange features a cast Zamak basket. Zamak is a rigid alloy of Zinc, Aluminum, Magnesium, and Copper. Zamak is non-magnetic.
Phase Plug: The bullet-shaped aluminum phase plug in the center of the midrange 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.
Voice Coil: The voice coil is wound around a 1" diameter low-mass Kapton former, ensuring no coil deformation.
Neodymium Magnets: The midrange drivers use Neodymium magnets, which have the same magnetic flux power as a ceramic magnet 10 times their size, reducing the size and weight of the speaker.
Size: The midrange drivers are not a standard size, approximately 3" diameter. It can be top or bottom mounted and has these dimensions:
- Depth (top mount): 1.4"
- Mounting height: 0.2"
- Flange height: 0.2"
- Depth (bottom mount): 1.6"
- Tweeter protrusion: 0" (zero)
- Cutout diameter: 2.883"
- Frame diameter: 3.47"
Tweeter
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°.
Tweeter/Midrange Mounting: Two surface mounting pods are included with the 165 KRX3 that hold a midrange and tweeter. The pods' dimensions are 6.856" x 4.114" x 3.123" (height above mounting surface).
Crossover
Components: Focal uses audiophile grade polypropylene capacitors and air core inductors to ensure high definition and a dynamic sound quality. There are five switches on the crossovers to adjust crossover points and output levels, offering a total of 162 different settings.
Bi-amp: The new crossovers included with the 165 KRX3 have bi-amp inputs, one input for the midrange/tweeter combination and one for the woofer. When using only two amplifier channels the crossover inputs are shorted together. Focal recommends using four amplifier channels to bi-amp the speakers for the improved dynamic range and to present an easier load for the amp(s) to drive.
Tweeter Adjustment: You can adjust the overall output level of the tweeter on the crossover; set to -6 dB, -3 dB, or 0 dB. Another switch allows you to emphasize the extreme (high) treble frequencies.
Midrange Level: The midrange output is also adjustable; set to -6 dB, -3 dB, or 0 dB. When the mids are installed low in the door, some of the output is absorbed by the upholstery and they can benefit from a higher output setting.
Crossover Points: There are three crossover frequency options for both the woofer (low-pass) and midrange (high-pass) outputs; the exact crossover points are not given. The upper frequency limit of the midrange output is not adjustable.
Wiring: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.315" wide.
