【Compatible with BMW X3 F25・X5 F15・X6 F16｜BMW-Specific 2-Way Trade-In System UPGRADE B-100W2】

You want the sound from your BMW factory audio to be a bit clearer. You want to be able to hear vocals and instruments more easily. This is a BMW-dedicated 2-way trade-in system speaker made for exactly those needs.

UPGRADE B-100W2 is a model designed to be installed on the door sheet metal side for vehicles such as the X3 F25, X5 F15・F85, and X6 F16. By replacing the factory speakers, you’ll find it easier to perceive the definition of the sound and the spread of the high frequencies, allowing you to enjoy your everyday music with a slightly different feel.

The tweeter uses a 25mm silk dome diaphragm and a neodymium magnet. It’s designed to make the high frequencies feel less harsh, reproducing vocals, cymbals, and more in a natural way. For the midrange, a 100mm paper cone combined with a ferrite magnet is used to bring out the information content of the mid and low-mid ranges.

The wiring is specified to connect using the factory coupler-on style, but the cohesiveness of the sound is not determined by the speaker unit alone. Since the overall impression changes depending on the condition of the door side, compatibility with your factory audio, and the installation method, if I were doing it, I would first confirm the vehicle and then combine only the necessary work. Let’s not rush into an overly large system—let’s decide together how far we want to improve the sound with a simple speaker replacement first.

Also, for the BMW X3 F25, the midrange spacers for the front and rear differ in shape between UPGRADE B-100W2 and UPGRADE B-100W. Compatibility varies by vehicle, so please be sure to check the shape of your factory speaker before purchasing. If it’s difficult to judge, let us know the vehicle model, year, and installation position, and we will check and guide you.
