About the Focal Inside IS MBZ 100

Alexander H.

Customized component sound for your Mercedes

Audio upgrades for Mercedes-Benz owners have historically been unimpressive. But now the Inside Series brings Focal's famous sound to your Benz. The best news of all is that Focal uses their flax woofer cones in their Inside IS MBZ 100 4" 2-way speakers. Focal discovered that a flax woofer cone produces a dynamic sound that's worthy of their reputation. At half the weight of fiberglass, these flax fibers help create a very rigid yet lightweight cone that ensures accuracy and limits unwanted vibrations.

What Focal is famous for

You'll find another Focal innovation in these speakers: the inverted dome tweeter. Focal includes premium inline crossovers to ensure optimal performance from the tweeters. Altogether, they achieve a clear, natural sound that lets you hear your music the way it was meant to be heard. Focal designs and builds these speakers to fit perfectly into a nice range of Mercedes vehicles. All the necessary mounting hardware is included, and integrated connectors connect to your existing factory speaker plugs — no cutting or splicing required.

Installation Note: Unless you're powering these speakers with an amplifier that has an active high-pass crossover, the included in-line filter must be used between the crossover and woofer.

Features

Mounting: The IS MBZ 100 component speaker set is a direct replacement for the factory speakers in select Mercedes Benz vehicles. Both the woofers and tweeters are direct, snap-in replacements for the factory drivers. Please enter your vehicle information to confirm fit.

Wiring: Each component crossover's input and output wires have factory plugs, so no splicing is necessary; the factory woofer harness plugs into the new crossover input. The crossover's 16" tweeter output wire plugs into the 12" wire attached to the tweeter and the 8" woofer output wire plugs directly into the woofer frame. If this speaker system is powered by any amplifier without an active high-pass crossover (including the factory radio), the additional included in-line filter (labeled protection patch on the box) must be used between the crossover and woofer.

Crossovers Dimensions:

  • Width: 2⅞" (4⅜" including wire)
  • Height: 1"
  • Length: 1½"

Q
These speakers can theoretically be used in other car brands, correct? I would assume so, as one would just need to cut the Mercedes specific adapters from the wire and add different ones? These would fit wonderfully in my F30 335i.

Greetings, and thank you for your question. Theoretically, yes. They are specific for Mercedes Benz because of the correct mounting brackets and direct plug in harness's. The speakers would work with any 4ohm system.

Q
Will the standard sound system in a 2017 MB C300 sedan adequately power these speakers?

The IS MBZ 100 component speaker set is a perfect direct replacement for the factory speakers in select Mercedes Benz vehicles Robert, and it does look like these sweet IS MBZ components fit both the Burmester and non-Burmester packages. Both the woofers and tweeters are direct, snap-in replacements for the factory drivers and are not only designed for the factory radio power they will also sound great! You can always add an amp if you choose, as these can handle a robust 50-watts RMS.
