Focal ES 100 K

Focal K2 Power ES 100 K | 4" 2-Way Component System

The Focal ES 100 K is an ultra-compact, high-performance component system from the iconic K2 Power series. Designed for audiophiles who need a small-footprint solution without sacrificing output, this 4-inch (100mm) kit features Focal’s signature aramid fiber sandwich cones. It is an ideal choice for high-end European vehicles (like BMW or Mercedes-Benz) that utilize smaller factory door or dash locations.

Product Highlights

• Aramid Fiber K2 Sandwich Cone: The famous yellow Kevlar® membrane combines lightness, rigidity, and damping. This triple-threat of characteristics ensures the woofer delivers dynamic sound with incredible definition and zero unwanted coloration.

• "M"-Profile TKM Tweeters: The inverted dome tweeters are made of aramid fibers and feature an exclusive "M" shape profile. This design allows for better control of dome deformation, resulting in high-frequency reproduction that is smooth, precise, and remarkably low in distortion.

• TMD® (Tuned Mass Damper) Surround: Originally developed for the Sopra home speakers, this surround technology stabilizes the cone's behavior at high volumes. It prevents deformation and ensures the midrange frequencies remain neutral and natural.

• Integrated Phase Plug (Ogive): The center of the woofer is equipped with a phase plug that improves the dispersion of sound throughout the car’s cabin, ensuring a clear and consistent soundstage regardless of your seating position.

Key Features

• Ultra-Compact Crossovers: The kit includes new-generation, compact crossover networks that are easy to hide behind door panels. They feature a tweeter level adjustment (0 / -3 / +3 dB) to help you match the high-end output to your car's interior materials.

• High Sensitivity: With a rating of 90 dB, these speakers are remarkably efficient for their 4-inch size, allowing them to deliver significant "punch" and volume even when space is limited.

• Precision Die-Cast Aluminum Basket: The rigid, non-magnetic basket provides a solid foundation for the motor assembly, eliminating parasitic vibrations that could interfere with the purity of the music.

• Versatile Tweeter Mounting: Focal includes various mounting accessories, including angled and recessed supports, making it easy to install the TKM tweeters in original factory locations or custom pods.
