Focal ES 100 KE

Focal K2 Power ES 100 KE | 4" 2-Way Component System (4th Generation)

The Focal ES 100 KE (Part Number: ES100KE) is the latest 4th-generation evolution of the legendary K2 Power series. While it retains the iconic yellow aramid fiber sandwich cones, this "KE" (Evo) version introduces significant technical refinements over the previous ES 100 K, including the all-new TKME tweeter and optimized TMD® surrounds. Designed and manufactured in France, it is the ultimate high-fidelity solution for compact factory locations where sound quality cannot be compromised.

Product Highlights

• 4th Gen K2 Sandwich Cone: This signature tri-layer cone uses an ultralight foam core sandwiched between aramid fiber and glass fiber. This combination provides the perfect balance of rigidity, lightness, and damping for a sound that is precise, dynamic, and free from coloration.

• New TKME "M"-Profile Tweeters: The "KE" edition features the updated TKME tweeter with an exclusive "M"-shaped inverted dome. This profile provides better control over dome deformation, extending the frequency response to 22 kHz while significantly reducing high-end distortion.

• Patented TMD® (Tuned Mass Damper) Surround: The woofer surround incorporates harmonic damping technology to stabilize the suspension. This eliminated erratic behavior between 1 kHz and 2 kHz, resulting in a remarkably neutral and realistic midrange.

• Progressive Profile Spider: The redesigned spider ensures better linearity and precision under high-excursion loads, allowing the 4-inch driver to maintain its composure even during complex, high-volume musical passages.

Key Features

• Neodymium Motor: Despite its compact size, the ES 100 KE utilizes a powerful Neodymium magnet to maintain high sensitivity and exceptional power handling for such a small-footprint driver.

• Optimized Compact Crossovers: The kit includes new-generation crossovers built with high-grade components selected for their thermal stability. They offer 3-level tweeter adjustment (0 / +3 / -3 dB) to fine-tune the acoustics for your cabin.

• Radial VC Cooling System: A specialized cooling system expels hot air from the voice coil through six dedicated holes. This improves reliability and limits heat compression, ensuring consistent performance during long listening sessions.

• Flexible OEM Fitment: The ultra-compact 1.5-inch mounting depth and included multi-mount tweeter hardware make this a preferred choice for luxury European vehicles like BMW, Mercedes, and Porsche.
