Meticulous design and construction

Handmade in France, the Elite K2 Power Series ES 165K2 component system is the culmination of Focal's passion for perfect sound, exceptional standards, and technological advances. Focal's sound gurus engaged in intensive listening sessions designing this line of speakers so that you hear uncanny realism, sweeping dynamics, and breathtaking depth in your music. This 2-ohm system extracts maximum power from your amp so you'll get more punch from your system.

A classic woofer with a new twist

The 6-1/2" woofer uses Focal's classic "W" sandwich cone design to reproduce your music with incredible accuracy. The nimble Kevlar and glass-fiber woofers demonstrate the control needed to play delicate classical passages, yet they'll handle the power needed to drive your bass-heavy tracks with authority. Focal adds a new Tuned Mass Damper (TMD®) rubber surround which minimizes harmonic distortion for the cleanest midrange possible. Focal also distinguishes this system by incorporating an aluminum phase plug in the woofer for extended frequency response.

A redesigned tweeter

The separate 13/16" aramid fiber tweeter employs a unique "M"-shaped inverted dome design that disperses the highs with remarkable precision, all the way up to 22,000 Hz. The 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. Three levels of tweeter control let you dial in the sound to your car's environment.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

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: Focal's patented butyl rubber TMD (Tuned Mass Damper) surround helps control unwanted resonances, providing a clean and neutral midrange with very low harmonic distortion.

Phase Plug: The bullet-shaped 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.

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

Size Classification Note: Some manufacturers, including Focal, call this size woofer a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size as a 6-3/4". Please enter you vehicle information to confirm fit in your vehicle.

Tweeter

Inverted Dome: The "M" profile, Aramid fiber, inverted dome tweeter is designed to increase precision at very high frequencies. The push-pull motor also damps acoustic resonances on the back of the membrane and extends the low end of the frequency response.

Mounting Options: The tweeter can be surface or flush mounted using the included adapters, or the trim ring can be removed and the protective washers added for mounting in a factory tweeter location. The included angled cup allows surface mounting at one of two angles; approximately 60° and approximately 40°.

Crossover

Components: Focal uses audiophile grade polypropylene capacitors and air core inductors to ensure high definition and a dynamic sound quality. Thermal camera imaging is used to optimize component power dissipation, improve reliability, and lower temperature.

Slope: The high-pass crossover slope is 12 dB/octave. A switch allows you to choose between 12 dB/octave and 6 dB/octave slopes for the low-pass crossover. The crossover point for both is 3,500 Hz.

Tweeter Level: A three position switch on the crossover allows you to adjust the output level of the tweeter to -3 dB, 0 dB, or +3 dB.

Tweeter Shelf: Another switch on the crossover turns on/off a high-frequency boost, designed to improve definition.

Bi-amp Inputs: Each crossover has bi-amp inputs, one input for the tweeter and one for the woofer. When using only two amplifier channels the crossover inputs must be shorted together using two short pieces of speaker wire. 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.

Wiring: The inputs and outputs are set screw terminals; they will accept bare wire up to 10 gauge.
