【2-Way Speakers Compatible with OEM Replacement for BMW & MINI｜UPGRADE B-100N】

This is the BMW-dedicated 2-WAY trade-in system UPGRADE B-100N, designed for those who feel a bit dissatisfied with the sound of their factory speakers, or who want to enjoy vocal and instrument sounds more naturally inside the cabin.

In addition to BMW models such as the E61, E60, and E70—where installation is possible on the door trim side—it is also compatible with the MINI front/rear speakers. With a plug-and-play coupler-on design that connects to the factory connector, it’s also easy to handle because you can replace the speakers without significantly changing the vehicle-side wiring.

The tweeters use a 25mm silk dome diaphragm and a neodymium magnet. Rather than simply boosting the high frequencies, the configuration is aimed at spreading naturally—capturing not only clear detail but also the breath of vocals and the resonance of instruments. For the midrange, a 100mm paper cone and a ferrite magnet work together to bring out the information content in the mid and low-mid range.

When replacing the factory speakers, even the music you always listen to may sound clearer in terms of sonic contours and vocal placement, potentially becoming easier to enjoy during long drives. Since the way it sounds can vary depending on the vehicle model and factory audio specifications, it’s important to choose carefully—not just by swapping speakers, but by also checking compatibility with the vehicle and the installation condition.

You can also combine it with the separately sold 10cm midrange high-pass filter UG B-100X HP. This is a part to consider based on your vehicle’s factory system and your preferred sound, such as when you want to organize how the low frequencies are handled.

Installation is basically coupler-on, but even for compatible vehicles, modifications may be required during installation due to specification changes, etc. Since BMW and MINI configurations differ depending on model year and audio specifications, we provide guidance after confirming your vehicle before actual installation.

At LOGON, we don’t just think about replacing the speakers alone—we also consider a practical setup together by looking at the condition of the door side and how it pairs with your existing system. If it were me, I’d first confirm the vehicle specifications and your current sound, then organize whether speaker replacement alone is enough—or whether combining other work would be better before moving forward.
