GZIW 250

Turn the heat of music into bass that reaches your chest.

【GZIW 250|Deep, Thick Bass in Your Car with a 25cm Subwoofer】

You want to add a bit more bass thickness and impact to your factory audio sound. But you don’t want a way of playing where only the bass stands out.

GZIW 250 is a 4Ω SVC subwoofer with a 10-inch (25cm) driver. While it’s designed with affordability in mind, it still uses an HQPP cone, a high-roll surround, and a POLYCOT spider. It firmly handles the low frequencies that form the foundation of music.

With the added bass, vocals and instruments can feel more three-dimensional, and your favorite songs can gain more depth. The role of a subwoofer isn’t simply to turn up the volume to create impact; it’s to support frequency ranges that are difficult for front speakers alone to cover.

It features a high-rigidity steel basket, a 50mm-diameter voice coil, and a magnetic circuit driven by a large ferrite magnet. The design focuses on solid core subwoofer performance, aiming for high-quality bass reproduction.

However, the impression you get from a subwoofer depends not only on the product you choose, but also on the box volume, installation method, the combination with the amplifier, and how it connects to the front speakers. If the bass becomes bloated, the music you worked hard to enjoy may become harder to listen to—so proper installation and tuning tailored to your vehicle and how you use it are important.

At Logon, we work together to determine the direction that will naturally gel across the entire car interior, confirming how much you want to enjoy the bass and what kind of music you usually listen to. It’s a model that’s easy to consult as one of your options, whether you’re adding a subwoofer for the first time or considering a system upgrade.
