【Trade-in Speakers for BMW & MINI｜UG B-100XW Coaxial 2-Way Speakers】

This is the UG B-100XW trade-in system speaker for BMW, designed for those who want to hear their music a bit more clearly when upgrading from the factory speakers.

It’s a coaxial 2-way type compatible with installation on the door sheet metal side, such as on F20, F21, F30, F31, F32, and others. It also fits the MINI front and rear speakers. Since it connects with a factory plug-and-play coupler, it’s an easy-to-enjoy setup that lets you experience the sonic change from the speaker swap without significantly altering the cabin atmosphere.

For the high-frequency range, it uses a silk dome tweeter; for the mid-low range, a 10cm paper-cone midrange. While making the contours of vocals and instruments easier to pick out, it reproduces a spacious, well-dispersed treble. It’s a speaker suited for anyone who wants to enjoy their usual music more clearly, with a natural balance.

The impression of the finished sound with a trade-in speaker can vary depending on the installation method and the condition of the vehicle side. For example: whether you proceed by replacing only the factory speakers, whether you add a dedicated high-pass filter, or whether you take the condition of the door side into consideration as well. If it were me, I would check the vehicle model, the factory audio specifications, and how you normally listen—then choose a configuration that’s practical and won’t be overcomplicated.

Even for compatible vehicle models, machining may be required during installation depending on specification changes and the vehicle’s condition. If you’re considering replacing the speakers in a BMW or MINI, we will guide you to the installation method that suits the actual car while checking the vehicle model, model type, year, and so on. If you’re unsure about the direction of the sound you want, let’s sort that out together.
