【Mercedes-Benz MB-100RX Dedicated｜2-Way Trade-In Speakers Enjoyed with a Direct OEM Replacement】

I want the sound of the factory speakers to be a bit clearer and wider. I want vocals to be easier to hear. But I’m not considering major modifications or system changes.

That’s where the Mercedes-Benz 2-Way Coaxial Trade-In Speaker MB-100RX, which is easy for Mercedes-Benz owners to consider, comes in. It is an OEM replacement type compatible with the front and rear doors. Without any vehicle-side modifications, it can be connected with a one-touch hookup to the original connector.

Fine-Tune the Sound’s Definition and Soundstage with an OEM Replacement

The MB-100RX is a 2-way configuration combining a tweeter for the high frequencies and a midrange for reproducing the mid-to-low frequencies.

The tweeter uses an aluminum dome diaphragm and a neodymium magnet. It makes it easier to bring out high-frequency information, so you can enjoy a different listening impression than with the factory speakers—capturing the breath of vocals and even the subtle details of instruments.

The midrange uses a 100mm paper cone and a ferrite magnet to reproduce the mid-to-low frequencies that form the foundation of music. Even the music you normally listen to will sound a bit more defined, and it’s a speaker that can help steer the sound toward being easier to enjoy during long drives.

Since the tweeter side is built in with a dedicated high-pass filter, it plays the audio by separating the necessary bands for a 2-way speaker.

Trade-In Design with Reduced Vehicle-Side Work

The wiring supports OEM plug-and-play (coupler-on), allowing you to connect it without any wiring modification on the vehicle side. It doesn’t drastically change the feel of the factory setup, and it’s also suitable for those who want to start with simply replacing the speakers.

However, even with the same speaker, the sound impression changes depending on the mounting condition and the condition of the door. It’s important not to stop at simply replacing the factory speakers—make sure to check and install everything from the mounting stability and nearby interference to the balance between the front and rear speakers.

At LOGON, we confirm your vehicle model and the specifications of your factory audio, as well as the music you usually listen to and your volume preferences—then we discuss together whether the MB-100RX is a good fit. If it were me, I would choose by checking the overall compatibility with the entire vehicle, rather than deciding the speakers first.

Of course, if you want to change the sound with an OEM replacement first, that’s great. And even if you don’t know how far you should go with modifications, you don’t need to force your way into a large system. Let’s consult on a way to create a sound that’s less likely to disappoint—while organizing what you can do with your current car.
