【USB-10｜Add Deep, Thick Bass to Your Car Interior with a 25cm Powered Subwoofer】

When listening to music on your factory audio, do you ever think, “I want a bit more thickness in the bass,” or “I want to feel the solid foundation of the music even without turning the volume up”?

USB-10 is a powered subwoofer that integrates a 25cm flat-cone woofer and a power amplifier. It has a built-in amplifier with a maximum output of 350W (175W×2), adding low-frequency ranges that are difficult to produce with the front speakers alone.

Rather than simply making the bass louder, it adds the “thickness” of the sounds beneath vocals and instruments, helping the overall music feel less thin. This model makes it easy to build a natural foundation for everything from rock and hip-hop rhythm to vocal tracks and music you listen to on long drives.

Because it uses a flat-type diaphragm, its overall dimensions are 275mm (W) × 82mm (H) × 369mm (D) despite being a 25cm model. It’s a size that’s easy to consider as an option for adding a subwoofer even in vehicles with limited installation space.

It supports high-level input, allowing connection even to OEM head units that lack pre-outs, and when using high-level input, the auto power-on function is also available. A level controller is included for adjusting volume from your hand, so it’s easy to use—keep it modest during everyday listening, and turn it up a little for songs where you want to enjoy the bass.

Important Considerations When Installing the USB-10

A subwoofer’s impression changes not only with the unit’s performance, but also with where it’s installed, how you route the power and signal cables, and how you connect it to the front speakers.

If only the bass comes forward, the overall music may be harder to keep cohesive. At LOGON, after confirming the vehicle’s audio configuration and usage, we adjust the low-pass filter and phase, and finish the installation while checking how it integrates with the front speakers.

This subwoofer is suitable not only for those who want sheer impact, but also for people who don’t want to drastically change the sound of their factory audio and simply want it to be a bit more enjoyable to listen to. Since the proposal may vary depending on the vehicle model and installation location, feel free to consult us if you’d like to decide the direction together, including the installation.
