Focal ES 100 K Overview

The ES 100 K 4” 2-way car component speakers from Focal are impressive, to say the least. Kevlar woofer cones, aramid woven fiber inverted dome tweeters, and the Tuned Mass Damper (TMD) rubber surround are just a few of the pieces of this complex, but super-sounding, speaker system.

Home Audio Sound, but for the Car

Most people think that it’s impossible to get really rich, clean sound from a car audio environment. That’s not true and the sound gurus at Focal prove it with the ES 100 K speakers. The 4” 2-way K2 Power component kit is comprised of some of the finest materials available to produce some really incredible sound. You won’t believe your ears.

Sandwiched Kevlar Woofer Cones and TMD® Surrounds

You might be familiar with Kevlar: it’s used in bulletproof vests, racing sails, bicycle tires, and many other things. It’s 5 times strong than steel, but quite light. It’s no wonder Focal turned to this material to use as woofer cones for their K2 Power line of speakers. Sandwiched between to ultra-thin layers of glass fiber, the Kevlar woofers are extremely musically accurate and a joy to listen to. To help minimize distortion, Tuned Mass Damper (TMD®) rubber surrounds are used to keep the woofers firing cleanly and accurately.

“M”-Shaped Woven Aramid Fiber Tweeters

The 13/16” tweeters found in the ES 100 K are just as unique as the woofers: they are a testament to Focal’s sound engineers unwilling to compromise on their quest to achieve perfection. The tweeters reproduce high-frequency response with stunning clarity without sounding “harsh” thanks to the woven aramid fiber design. The sound is less directional than tweeters from other manufacturers thanks to the “M”-shaped inverted dome tweeter that Focal employs that is capable of wider dispersion.

Allow Us to Suggest…

To properly power these speakers (assuming you are using just a pair of ES 100 K speakers in your setup), we would recommend a 2-channel amplifier that is stable at 4 ohms. Ideally, the power output of this amplifier at 4 ohms would fall around 60 watts per channel.

The next thing we would suggest is to use a Dynamat Xtreme door kit to provide sound insulation. In doing so, you’ll receive better mid-bass performance as well as help reduce incoming road noise through your vehicle’s thin metal doors so you can better hear your new speakers. There is enough Dynamat Xtreme material in this kit to provide sound insulation for a pair of doors.

What is the resulting sound from these speakers if no crossover is used?
A shopper on Mar 16, 2019
  Crossovers must be used with this speaker kit. The appropriate frequencies must be sent to the correct speaker (tweeter or woofer) or else damage can occur. It is NOT recommended that component speakers such as this kit are used without crossovers unless you are using a bi-amping or bi-wiring method.
Can I use the crossover that was part of the original stereo system from the factory with aftermarket component speakers?
A shopper on Aug 22, 2020
  Hi there and thanks for reaching out to us! We generally don't recommend this method as it's hard to find the information pertaining to the original crossover's specifications. They may end up choking the Focal tweeters back to a point where you will be disappointed with the performance of a very fine-sounding speaker system. It would be best to use the crossovers that came with the Focal kit.
