Focal IS MBZ 100 | Plug & Play Mercedes-Benz Component Speaker Upgrade
Vehicle-specific 2-way Flax component speakers for selected previous-generation Mercedes-Benz factory locations.
Natural, Detailed Sound for Compatible Mercedes-Benz Vehicles
The Focal IS MBZ 100 is a vehicle-specific 2-way component speaker kit designed to improve the clarity, tonal balance and soundstage of selected Mercedes-Benz factory audio systems.
The kit combines 100mm Flax-cone midrange drivers with separate aluminium inverted-dome tweeters. This component arrangement provides clearer vocals, improved instrument separation, more detailed high-frequency reproduction and stronger midrange definition while retaining compatible original speaker locations.
The IS MBZ 100 is intended for factory positions that provide separate midrange and tweeter locations. The exact vehicle, audio package and speaker position must be confirmed before purchase.
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 Mercedes-Benz Component Speaker Design
The 100mm Flax driver and aluminium tweeter install in separate compatible factory locations. The midrange driver reproduces vocals and instruments, while the separate tweeter handles treble and fine high-frequency detail.
Positioning the tweeter higher in the cabin helps lift the perceived soundstage and can place vocals and instruments closer to dashboard level for a wider and more focused presentation.
100mm Flax Sandwich-Cone Midrange Drivers
Focal’s Flax sandwich cone uses natural flax fibres positioned between thin layers of glass fibre. The construction balances low mass, rigidity and damping to support natural midrange reproduction without unnecessary colouration.
Vocals, guitars, piano and percussion gain improved texture and definition, while complex recordings remain easier to follow.
The 100mm measurement refers to the midrange driver. The separate high-frequency driver is an aluminium inverted-dome tweeter.
Aluminium Inverted-Dome Tweeters
The separate aluminium inverted-dome tweeters provide controlled high-frequency response and broad dispersion. Their low-directivity design supports stable soundstage width across the front seating area.
Cymbals, strings, vocal harmonics and subtle recording details become easier to distinguish. Correct tweeter location, orientation and polarity remain important to achieving the intended result.
Focused Midrange Rather Than Deep-Bass Reproduction
The IS MBZ 100 has a published frequency response of 150Hz-20kHz. It is designed primarily to improve vocals, instruments, treble detail and overall soundstage definition.
The kit is not designed to reproduce deep bass. Compatible Mercedes-Benz subwoofers or factory bass drivers remain responsible for lower-frequency reproduction.

4-Ohm Design for Compatible Factory Systems
The IS MBZ 100 has a nominal impedance of 4 ohms and can operate in selected Standard, Advanced and Burmester systems where Focal specifically lists the application.
Electrical compatibility must be confirmed separately from physical fitment. Factory equalisation, active filtering and channel processing may remain after the speakers are replaced.
Factory Speaker Replacement and Amplifier Upgrades Require Separate Checks
Compatibility as a replacement speaker does not automatically mean that a Focal Impulse amplifier and Y-ISO harness can be added to the same vehicle.
Focal aftermarket amplification solutions are generally limited to selected non-amplified systems. Vehicles equipped with factory amplifiers or premium hi-fi systems require a different integration assessment.
Vehicle-Specific Plug & Play Integration
The IS 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 Model Applications
The IS MBZ 100 is listed for selected applications across model groups including the Mercedes-AMG GT 4-Door Coupe, C-Class, CLS, E-Class, EQC, EQV, G-Class, GLC, Marco Polo and S-Class.
These are broad model families rather than confirmation that every production year, body style, market specification, audio package or speaker position is compatible.
Front and Rear Speaker Positions Can Differ
Depending on the vehicle, the IS MBZ 100 may be specified for front doors, rear doors or another component-speaker position.
Locations that do not provide a separate tweeter may require an IC MBZ coaxial speaker instead. Dedicated surround and centre-channel positions require the ICR MBZ 100 or ICC MBZ 100 where listed.
Build a Complete Focal Inside Mercedes-Benz System
A complete system can combine the IS MBZ 100 with compatible rear speakers, the ICC MBZ 100 centre channel, ICR MBZ 100 surround speakers and the correct right-hand-drive ISUB MBZ 2 subwoofer pair.
Each product must be confirmed for the exact vehicle position and original audio architecture. System balance depends on the factory source signal, amplifier processing and installation quality.
Made in France
The IS MBZ 100 is developed and manufactured by Focal in France. Its Flax drivers, aluminium tweeters and vehicle-specific construction combine Focal loudspeaker technology with discreet Mercedes-Benz integration.
Retain the Original Mercedes-Benz Interior
In a confirmed application, the IS 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.
