Focal 4 Inch Two-Way Coaxial Kit - RCX100

Online Only




Upgrade your car’s factory system with a kit that is easy to install and capable of even better performance than the previous generation. Rediscover the pleasure of driving to your favourite music with speaker drivers wired to your current head unit.

This coaxial kit is now equipped with Focal’s famous inverted dome tweeters to provide excellent linearity. The high sensitivity of this kit will set it apart from your vehicle’s factory system. Auditor makes Focal technology and performance available to all drivers.

Grills are supplied.


The car audio kits in the Auditor line feature high-end technology: they still have a 1" (25mm) voice coil on a kapton frame, a powerful 31/3" (85mm) magnet, a matt black polypropylene cone and butyl suspension...but the new feature for 2017 is our famous inverted dome tweeter, a key representative of Focal’s core values. The Mylar used for the dome allows for a combination of extremely low mass, minimal directivity and excellent linearity in the high end, something which is unprecedented in this price range.


The design of the steel baskets is clearly inspired by the Performance ranges, recognisable by the double arms. The design of the tweeter can be easily installed in the vehicle’s factory locations.


New grilles have also entered the scene (except on the RCX-570 kit). Their relatively flat shape and mesh structure provide excellent dispersion, and succeed in reconciling aesthetics, optimal integration and high performance.
