【BMW-Specific 2-Way Trade-In System Speakers UPGRADE B-100W｜Enjoy a Natural Sound with a Direct Replacement】

You may not be dissatisfied with the factory BMW speakers, but you might feel that the vocals are a little too far away, the sound seems muffled, or you want to enjoy music with a bit more spaciousness. If that sounds like you, consider the BMW-Specific 2-Way Trade-In System Speaker UPGRADE B-100W.

A BMW-specific design that supports installation on the door sheet-metal side, such as on the F20 / F21 / F30 / F31 / F32, etc. By replacing the factory speakers, you can increase the amount of sonic information and enhance the spread of the high frequencies, making the sound more like you can easily perceive the positions of vocals and instruments in your usual music.

The tweeters use a 25mm silk dome diaphragm and a neodymium magnet. The design avoids overemphasizing the treble with a hard, sharp character, so you can enjoy natural extension and spaciousness. The midrange combines a 100mm paper cone with a ferrite magnet, aiming at clear reproduction from the midrange—including vocals—down to the mid-bass.

It also supports plug-and-play wiring that connects to the factory connector, allowing you to replace the speakers while keeping wiring modifications to a minimum. However, speaker replacement alone is not what determines the final sound. The impression of the finished result can vary for the same product depending on the condition of the mounting surface, the mounting method, what is done on the door side, and how the tweeter is integrated.

At LOGON, we organize and guide the necessary work while confirming your BMW’s factory audio configuration and vehicle specifications, the music you usually listen to, and your preferences for volume. If it were me, I would first check the condition of the factory speakers and installation requirements, then decide in an actual vehicle whether B-100W alone is sufficient or whether it would be better to combine it with a dedicated high-pass filter, etc.

The speakers are also compatible with the MINI front/rear speakers, but for the F25 X3, the front/rear midranges use different spacer shapes between UPGRADE B-100W2 and UPGRADE B-100W. Before purchasing, please be sure to check the shape of your factory speakers.

These speakers are intended for people who want to make the time spent listening to music inside the cabin feel a little more enjoyable. Since the ideal configuration can change depending on the vehicle model and factory audio specifications, if you’re unsure, let’s confirm together based on your vehicle.
