【RS-X12 30cm Subwoofer｜For Those Who Want Solid Bass】

You want a bit more thickness and impact in the low end from your factory audio.
Not only when you turn the volume up, but also so you can enjoy the music you normally listen to more comfortably.

If that sounds like you, you should consider the RS-X12 30cm subwoofer.

This subwoofer uses a 12-inch (about 30cm) paper cone, and is designed to handle the low frequencies that are difficult to reproduce with door speakers alone. It doesn’t just increase the amount of bass—by sharing the role with the front speakers, the overall sound may gain more body, and vocals and instrument notes may become easier to hear.

Thanks to its larger size, it’s ideal for anyone who wants to enjoy bass rhythms—such as in rock or hip-hop—as well as for reinforcing a factory system that can feel like it has restrained bass. Even if you want the bass to hit hard, it’s not simply a matter of turning it up. It’s important to adjust it while checking the connection with the front speakers and how it sounds inside the cabin.

For the RS-X12, the box capacity is roughly about 48L for a vented design and about 32L for a sealed design. Since the way the bass sounds and how well it “comes together” varies depending on the box type and volume, you’ll want to choose while considering your in-car space, your preferred sound, and how it will pair with the amplifier you use.

At Log On, we don’t think about the subwoofer on its own. We organize the installation method and adjustment details together based on your current audio system, the space inside your vehicle, and the music you usually listen to. Even with the same subwoofer, the final impression will change depending on how you combine it and how far you take the adjustments.

For those who want to add solid bass to the cabin while prioritizing cost performance, this is a model that’s easy to consider. If you’re unsure about how the bass will turn out, tell us first what you’re dissatisfied with in your current sound and what music you want to hear. Let’s think together about the best approach for your car.
