【APBX 10AS2 | Amplifier-Integrated Subwoofer Adding Low-End Thickness to OEM Audio】

If your OEM audio system—or a system you’ve upgraded by replacing speakers and adding an amplifier—could use a bit more low-bass thickness and a sense of scale, then consider the APBX 10AS2.

This box-type model integrates a 250mm Prima APS10DS subwoofer with an amplifier, delivering a rated output of 400W RMS. It not only increases the quantity/impact of low bass, but also makes it easier to feel the contours of the bass and bass drum, as well as the foundation of the entire track. Rather than bass that gets in the way of vocals or the mid/high range, it’s designed to support the sound of your front speakers from below.

The enclosure uses a sealed (shielded) type design. With a sealed configuration, you can more easily target a cohesive low-end, making it a great option for those who like to listen to music carefully and attentively. The mounting depth is only 158mm and the unit is slim, so it’s easier to fit into limited spaces. If you don’t want to sacrifice a lot of luggage space but still want to add a solid subwoofer, this is a practical choice.

Using the included bass level controller HRC AP, you can adjust the low-end quantity right from the unit depending on the song or your mood. It’s also a nice feature that you can enjoy it in different ways—keeping it natural on a daily basis, or adding a bit more thickness for tracks where you want extra punch.

A subwoofer won’t produce the same sound just because it’s installed. It’s important to adjust the volume and frequency range while checking how it connects with the front speakers and how it sounds inside the cabin. At Log-on, we evaluate your current OEM setup, the speakers you already have installed, and how you use the vehicle, then perform installation and tuning so that only the bass doesn’t stand out and the whole piece comes together naturally.

This subwoofer is recommended not only for those who feel they’re lacking in low bass, but also for anyone who isn’t planning a major system change yet wants to enjoy their usual music in a more satisfying way.
