B-150USB

The B-150USB adds a satisfying low-bass thickness to your usual drive.

【BMW B-150USB 20cm Under-Seat Subwoofer】

This 20cm trade-in type under-seat subwoofer is designed for those who want to add a bit more presence and depth to the bass in their BMW’s factory audio system.

By replacing the factory subwoofer, the lower frequencies that form the foundation of your music become easier to reinforce, allowing you to hear vocals and instruments with a little more breathing room. Rather than simply making the bass louder, this model is for people who want to enjoy their usual music more solidly.

Since the wiring is designed to connect to the factory connector, the installation can be done without significantly changing the vehicle-side wiring. However, compatibility and installation methods may differ depending on the BMW model year and the specifications of the factory audio system. This product cannot be used on vehicle models where the factory subwoofer is bonded to the enclosure, so we will guide you after confirming your vehicle in advance.

The unit features a 20cm paper cone, a powerful ferrite magnet, and a large damper. Its design aims to deliver well-damped bass within the limited space available under the seat.

If you plan to replace both the left and right units, you will need 2 units. This product is sold per unit.

At LOGON, we don’t just install the product—we also check the overall balance to ensure the bass doesn’t stand out too much, while considering the balance with the vehicle’s factory system and the front speakers. If you want a bit more depth in your BMW’s sound, let’s decide the direction together while confirming the model, year, and factory audio specifications.
