Focal IS MBZ 100 Mercedes-Benz 4" 2-Way Component Speaker Kit

The Focal IS MBZ 100 is a premium 2-way component speaker kit specifically developed for select Mercedes-Benz vehicles as part of the acclaimed Focal Inside range. Designed as a direct Plug & Play replacement, the IS MBZ 100 delivers significantly improved sound quality while preserving the factory appearance and functionality of the vehicle.

At the heart of the system is Focal’s renowned Flax sandwich cone technology, manufactured in France and engineered to provide natural midrange reproduction, exceptional vocal clarity and outstanding tonal accuracy. The lightweight yet rigid Flax diaphragm allows the speaker to reproduce music with remarkable realism, bringing greater detail and emotion to every listening experience.

High frequencies are handled by Focal’s aluminium inverted dome tweeter, a signature technology known for delivering smooth, detailed and highly accurate treble response. This combination creates a wider soundstage, improved stereo imaging and enhanced spatialisation throughout the cabin, transforming the factory audio system into a true hi-fi listening environment.

To maximise performance within the limited space available in factory mounting locations, the IS MBZ 100 incorporates a compact neodymium motor and vehicle-specific design. Installation is simple and discreet, requiring no modifications to the vehicle's interior or original wiring, making it an ideal upgrade for Mercedes-Benz owners seeking premium sound quality without compromising OEM integration.
