Description
Meticulous design and construction
Handmade in France, Focal’s ES 100 KE 4″ component speaker system is the culmination of Focal’s desire for perfect sound. Focal’s sound gurus engaged in intensive listening sessions designing this line of speakers so that you experience uncanny realism, sweeping dynamics, and breathtaking depth in your music.
A classic woofer with a twist
The ES 100 KE uses Focal’s classic “W” sandwich cone design for incredibly accurate audio reproduction. 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 Tuned Mass Damper (TMD®) rubber surround to the woofer design which minimizes harmonic distortion for the cleanest midrange possible.
These crossovers direct frequency traffic to the woofer and tweeter, while also providing you settings to get just the right sound.
A tweeter designed for smooth highs
This system’s 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 and one for the woofer let you dial in the sound to your car’s environment.

Features
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.
Neodymium Magnets: Each driver 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.
Tweeter Mounting Options: The tweeters can be surface or flush mounted using the included adapters, or the trim rings 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°.

| Frame Width | N/A | 2.075″ | 2.075″ |
| Frame Depth | N/A | 2.125″ | 1.957″ |
Crossovers: The inputs and outputs are screw terminals; they will accept bare wire or spade connectors up to 0.315″ wide. The crossovers use 2nd order (12 dB/octave) low-pass and high-pass filters; the crossover point for both is 3,500 Hz. A three position switch on each crossover allows you to adjust the output level of the tweeter to -3 dB, 0 dB, or +3 dB. 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.
Crossover Dimensions:
- Width: 4⅜”
- Height: 1¼”
- Depth: 3″
