K2 Power, Fourth Generation
Focal's K2 Power range is built around its iconic yellow cone — a longstanding symbol of power and dynamics. The fourth generation continues that tradition, delivering pure hi-fi sound on board.
Ultra-Compact
The ES 100 KE is highly sensitive for its size and fits a wide range of vehicle interiors and configurations. Speaker drivers use the K2 cone — Focal's yellow aramid-fibre innovation — combining lightness, rigidity and damping for dynamic, highly defined sound. Central ogive cones help to disperse sound more evenly throughout the passenger compartment.
The TKME tweeter complements the midrange with smooth treble reproduction. Also made from aramid fibres, its inverted dome uses an exclusive M-shaped profile to control cone deformations and limit distortion.
The kit includes a compact crossover, making in-vehicle installation and adjustment straightforward. The TKME tweeter can be mounted in factory locations, flush-fitted or on angled brackets. Aluminium grilles are included.
K2 Sandwich Cone
The aramid fibre cone features an ultralight foam core sandwiched between a thin layer of aramid fibre and a layer of fibreglass. This construction delivers the three acoustic essentials — rigidity, lightness and damping — for precise, dynamic sound reproduction.
TKME Tweeter
The M-profile TKME tweeter extends frequency response to 22kHz with reduced distortion for smooth, precise high-treble diffusion. A push-pull motor based on IAL2 technology achieves very low resonance frequencies for harmonic balance.
More Linearity and Precision
The progressive spider on the K2 Power driver uses a progressive section to reproduce bass impact accurately and improve linearity, precision and dynamics.
Increased SPL
The Radial VC cooling system expels hot air from the voice coil through 6 holes towards the bottom of the motor. This controls coil temperature, limits heat compression, improves reliability and increases dynamic output.

About the Focal ES 100 KE
From our tech experts at CEN
Focal K2 Power Series 4 inch component speakers, with separate tweeters that can be mounted where you will actually hear them, rated at 60w RMS.
Who it suits
Drivers building a proper front stage and happy for tweeters to be mounted separately, which usually means a professional fit. K2 Power is Focal’s long-running aramid-fibre range, the one enthusiasts recognise by the yellow cone.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker, and Focal drivers repay an amplifier. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: What size is the Focal K2 Power ES 100 KE?
A: It is a 4-inch (100mm) 2-way component kit with a mounting depth of 39mm, which makes it suitable for compact speaker locations.
Q: How much power can the ES 100 KE handle?
A: It is rated at 60W RMS nominal and 120W maximum, with 4 ohm impedance and 90dB sensitivity.
Q: Can the ES 100 KE tweeters be mounted in different positions?
A: Yes. The TKME tweeter can be mounted in the factory locations, flush-fitted or on angled brackets, and the kit includes woofers, tweeters, crossovers, grilles, speed clips, screws and an owner's manual.
