About the Focal ACX 100

The benefit of Focal innovation
The benefit of Focal innovation
Focal designed their updated Auditor EVO Series speakers in France. That's a big deal — it means that these entry-level car speakers were reimagined by some of the same minds that design their flagship models. You'll recognize staples of Focal's famous sound: the inverted dome tweeter for precise treble and an improved soundstage; a polypropylene cone for a neutral and dynamic sound; and a butyl surround for impressive responsiveness.
The aim of Auditor EVO
Focal's goal is to improve the audio experience in any type of car, and these impressive ACX 100 4" coaxial speakers will easily outperform your factory speakers and bring the fun back to your drive time. Prepare for a new level of richness in the midrange, and Focal's acclaimed inverted dome tweeter, with its handsome black lacquered finish, broadcasts high-frequency details that put standard tweeter designs to shame. An integrated, high-fidelity crossover ensures that the woofer handles only the lower frequencies and the tweeter only handles the highs, giving you a smooth sound overall.
Ready to ride
A polypropylene woofer cone and butyl rubber surround help these speakers live a long life in your car doors, withstanding all kinds of environmental abuse while delivering robust sound.

Features
Woofer: The polypropylene cone and butyl rubber surround are resistant to the temperature extremes and humidity often found in the automotive environment, adding to the speaker's reliability and longevity.
4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The ACX 100's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please enter your vehicle information to confirm fit.

First time buyer of these French speakers and glad I did. They sound magnificent in my 2022 Bronco. They fill the cabin with crystal clear highs and zero distortion at peak power!
