【UP W8MB-S4 LHD｜20cm Trade-in Subwoofer for Left-Hand-Drive Vehicles】

You want a bit more bass thickness and depth in the sound from the factory audio. However, there’s no need for a box-type subwoofer that takes up a large portion of the trunk.

That’s where the UP W8MB-S4 LHD comes in—it’s an easy option to consider. Designed for left-hand-drive vehicles, this 20cm trade-in type subwoofer supplements the low-frequency range that’s hard to produce with front speakers alone, while making effective use of the limited space inside the cabin.

The 20cm woofer unit uses a lightweight, high-rigidity paper-cone diaphragm. In addition, the magnetic circuit driven by a powerful neodymium magnet is designed not only to deliver satisfying bass quantity, but also to focus on the bass response—its initial attack and fine nuances.

The playback frequency response is 25Hz to 250Hz. Because it’s tuned primarily for the subwoofer band, it’s easier to separate the roles and frequency ranges from the front speakers, making it simpler to integrate the overall sound. Adding punch to bass and kick drum contours, as well as low-effect sounds from movies and music, helps you achieve a natural, well-balanced thickness across the soundstage.

A subwoofer isn’t something you choose simply by making it play louder. The final impression depends on factors such as the installation method, the available space in the vehicle, compatibility with the front speakers, and the crossover settings. It’s important to adjust it so that the bass doesn’t stand out on its own and instead blends naturally with the sound from the front.

At LOGON, you can consult with us about whether adding a subwoofer makes sense, including by confirming your vehicle model, the configuration of your factory audio, the music you usually listen to, and your preferences for bass. If you want to add more thickness to your sound but don’t want to make major changes inside the car, try considering it together based on your specific vehicle—just once.
