Focal ICR MBZ 100 | Plug & Play Mercedes-Benz Surround Speaker Upgrade
Vehicle-specific 2-way coaxial surround speakers for selected dedicated Mercedes-Benz rear surround locations.
Detailed Surround Sound for Compatible Mercedes-Benz Vehicles
The Focal ICR MBZ 100 is a vehicle-specific 2-way coaxial surround speaker kit designed for selected Mercedes-Benz vehicles equipped with dedicated surround-speaker locations.
Each speaker combines a 100mm Flax midrange cone with an integrated high-frequency driver. The kit improves rear spatial detail, vocal clarity and sound-field continuity while retaining compatible factory speaker locations.
The ICR MBZ 100 is not a general rear-door replacement. It should only be installed where the current Compatibility Guide identifies a dedicated surround position.
Mercedes-Benz Factory Audio Compatibility
Compatible with selected Mercedes-Benz vehicles equipped with Standard, Advanced or Burmester factory audio systems where specifically listed. Compatibility varies by model, production year, market, speaker position and factory audio configuration. Focal aftermarket amplification solutions are not compatible with vehicles equipped with factory amplifiers or premium hi-fi systems unless a separate approved integration solution is specifically identified. Please refer to the Compatibility Guide or contact your nearest Authorised Focal Australia Dealer to confirm compatibility.
Mercedes-Benz vehicles can use different factory amplifiers, speaker impedances, connectors, equalisation and channel-specific processing. A speaker that physically fits a factory location is not automatically compatible with every original audio configuration.
Confirm the exact model, chassis code, production date, body style, factory audio package and intended speaker position before purchase.
2-Way Coaxial Surround Speaker Design
The midrange cone and high-frequency driver share the same compact chassis. This allows the speaker to reproduce a broader frequency range from a single factory surround location.
The kit is commonly used in selected rear parcel-shelf or dedicated rear surround positions, depending on the vehicle’s original speaker layout.
100mm Flax Sandwich-Cone Midrange Drivers
Focal’s Flax sandwich cone balances low mass, rigidity and damping through natural flax fibres placed between thin glass-fibre layers.
The construction supports natural midrange reproduction, helping rear vocals, instruments and ambient information sound clearer and better integrated with the front soundstage.
Integrated High-Frequency Reproduction
The integrated high-frequency driver adds treble detail without requiring a separate tweeter location.
This supports a compact coaxial installation within the dedicated Mercedes-Benz surround opening. Correct polarity and system balance remain important to avoid excessive rear emphasis.
Surround Fill Rather Than Primary Front-Stage Output
The ICR MBZ 100 is designed to support spatial information and rear sound-field continuity rather than replace the primary front component speakers.
Rear surround levels should complement the front soundstage. Excessive rear output can pull vocals and instruments behind the listener.

4-Ohm Design for Compatible Factory Surround Channels
The ICR MBZ 100 has a nominal impedance of 4 ohms. The connected factory or aftermarket surround channel must be suitable for this load and the speaker’s power rating.
Factory channel equalisation, filtering and level control may remain after the speakers are replaced.
Vehicle-Specific Plug & Play Integration
The ICR MBZ 100 uses dedicated Mercedes-Benz connections and mounting provisions for selected compatible factory locations. In confirmed applications, the original speaker wiring can remain intact.
Plug & Play describes the dedicated electrical connections and vehicle-specific mounting design. It does not mean universal Mercedes-Benz compatibility or guarantee that every installation can be completed without careful trim removal, acoustic sealing, replacement clips or minor adjustment.
Selected Mercedes-Benz Surround Applications
The ICR MBZ 100 is listed for selected surround positions in model groups including the C-Class, E-Class, EQS, G-Class, GLE and S-Class.
These model names do not confirm that every vehicle has dedicated surround openings or the correct factory channel. Verify the exact model, production year and audio package.
Difference Between Surround, Rear-Door and Centre Speakers
The ICR MBZ 100 is designed for dedicated surround positions. Standard rear-door positions may require an IS MBZ component kit or IC MBZ coaxial kit instead.
The dashboard centre channel requires the ICC MBZ 100 where specifically listed. These products should not be treated as interchangeable.
Build a Complete Mercedes-Benz Surround System
The ICR MBZ 100 can form part of a complete system with compatible IS MBZ front and rear component speakers, the ICC MBZ 100 centre channel and the correct ISUB MBZ right-hand-drive subwoofer pair.
The final result depends on the number of factory channels, original signal processing and correct level matching between the front, centre, surround and bass speakers.
Made in France
The ICR MBZ 100 is developed and manufactured by Focal in France. Its Flax cone, neodymium motor and moulded aluminium structure combine compact construction with vehicle-specific integration.
Retain the Original Mercedes-Benz Interior
In a confirmed application, the ICR MBZ 100 remains concealed behind compatible original trim and factory speaker grilles. The dashboard, doors, floor area and vehicle controls retain their original appearance.
The installation can remain substantially reversible when the original wiring, connectors, mounting points and surrounding trim are preserved.
Professional Installation Recommended
Professional installation by an Authorised Focal Australia Dealer is recommended. The installer can identify the factory audio package, confirm the exact speaker location, verify electrical compatibility and complete the installation without damaging trim, wiring or safety systems.
Confirm Compatibility Before Purchasing
Compatible with selected Mercedes-Benz vehicles equipped with Standard, Advanced or Burmester factory audio systems where specifically listed. Compatibility varies by model, production year, market, speaker position and factory audio configuration. Focal aftermarket amplification solutions are not compatible with vehicles equipped with factory amplifiers or premium hi-fi systems unless a separate approved integration solution is specifically identified. Please refer to the Compatibility Guide or contact your nearest Authorised Focal Australia Dealer to confirm compatibility.
Do not rely solely on the vehicle model name, approximate speaker size or the presence of a matching connector. Confirm the chassis code, production date, factory audio package and intended speaker position before ordering.
