【APBX 8AS2｜An amplifier-built tune-up woofer that adds low frequencies without taking up space】

Once you replace the factory speakers and amplifier and the sound’s definition starts to settle, the next thing that’s easy to notice is how thick the low end sounds.

Although the vocals and instrument tones have become easier to listen to, you want a bit more impact across the whole of the music. Even if you turn the volume up, only the bass can feel light. If that sounds like you, consider the Tuned Woofer APBX 8AS2.

By adding it to a car audio system you’ve upgraded with an amplifier and speakers, it supports the low frequencies that are difficult for front speakers alone to cover, and adds thickness to the overall sound. Rather than simply making the bass louder, you can stabilize the foundation of the music and bring out a different way of hearing your usual tracks by tuning it while considering how it connects with the front speakers.

A design that makes it easy to keep installation space down with a slim box

The APBX 8AS2 is a shielded box with a built-in amplifier and a 200mm woofer.

Using a special cone-dustcap-basket shape, it keeps the installation depth under control while still ensuring large woofer excursion. With a box size of 386mm × 294mm × 158mm, it’s a slim model, making it easier to consider even for limited in-car space.

It’s suitable for those who don’t want to use much of the luggage space, and for those who want to add low frequencies without changing the usability inside the cabin as much as possible. However, since the actual mounting location and fixing method vary depending on the vehicle model and interior shape, it’s important to check the actual car before installing.

Think not only about the amount of bass, but also about the cohesiveness of the entire system

A subwoofer isn’t something that will sound good just by being installed.

If the volume balance with the front speakers and the way the low frequencies connect don’t match, you may find that only the bass stands out, or that the entire music feels heavy. To make the most of the APBX 8AS2, it’s important to set up a reasonable configuration while checking compatibility with the vehicle’s factory system and your existing amplifier and speakers.

At LOGON, we confirm the vehicle model, your current system, the music you normally listen to, and the direction you want for your bass, and then work with you to decide how to combine everything.

If you want impact but want to avoid bass becoming overly strong, I would first check the overall balance and adjust it so you add only the necessary amount in a natural way. Most important of all is that you can enjoy the music comfortably after installation.

Using the included Bass Level Controller HRC AP, you can adjust the bass quantity feel according to the music or your mood. Because the appropriate connection and installation methods vary depending on the vehicle model and system, if you’re considering the APBX 8AS2, please tell us your current audio setup and the vehicle model. We’ll guide you to a sensible combination while checking an actual vehicle.
