About the Focal ES 100K
Meticulous design and construction
Focal incorporates their Tuned Mass Damper (TMD®) rubber surround for excellent woofer control and minimal distortion.
Meticulous design and construction
Handmade in France, the Elite K2 Power Series ES 100K 4" component speaker 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.
A classic woofer with a new twist
The ES 100K uses Focal's classic "W" sandwich cone woofer design to reproduce your audio 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 to the woofer design which minimizes harmonic distortion for the cleanest midrange possible.
A redesigned tweeter
The separate 13/16" tweeter employs a one-of-a-kind "M"-shaped inverted aramid fiber dome design that does a better job than ever of dispersing 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.

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" diameter low-mass Kapton former, ensuring no coil deformation.
Neodymium Magnets: Each woofer uses a Neodymium magnet, which has a magnetic field strength similar to a ceramic magnet approximately 10 times its size, reducing the size and weight of the speaker.
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°.
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 crossover uses 2nd order, 12 dB/octave low-pass and high-pass filters. 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.
Band-Pass: Another switch (on/off) on the crossover allows you to engage a 12 dB/octave high-pass crossover to remove the lower bass from the 4" woofer.
Wiring: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.315" wide.
