【GZUM 55SQ｜Refine the mid-to-high range with 5.5cm mid-range speakers】

You may feel that the vocals sound a little distant, or that the entire music track feels muffled. In such cases, there’s an alternative to simply increasing the bass: revisiting the mid-range speakers that handle the presence of vocals and instruments.

GZUM 55SQ is a 5.5cm mid-range speaker. It covers the 500Hz–11kHz range and is responsible for the mid-to-high frequencies that strongly influence the overall impression of music—vocals, guitar, piano, and more. Even with songs you already listen to, this speaker aims to clarify the center of the sound, making it easier to confirm the vocal position and the contours of instruments.

The diaphragm uses a silk dome with a special coating. In addition, it combines a company-designed basket design with a neodymium basket. This configuration makes use of the compact size while being suited to those who want strong transient response and detailed expression.

Mid-range speakers: your impression changes with the installation

Mid-range speakers are not something you can just install and be done. The way vocals come through and how well the overall image comes together can change depending on the connections with existing speakers and tweeters, the amplifier/DSP, as well as the installation position, orientation, and volume balance.

To get the most out of the GZUM 55SQ, it’s important to check the vehicle model and your current audio setup, then consider which frequency range to assign to it and how to connect it with other speakers. If I were doing this, I wouldn’t decide based only on replacing the product by itself—I would confirm what kind of sound you want to achieve in the car, and then build the installation plan accordingly.

If you feel, for example, “I want the vocals a bit more forward,” “I’m not satisfied with the sound of the factory speakers,” or “The tweeters alone don’t provide enough body,” please feel free to consult us. We’ll think together about whether incorporating the GZUM 55SQ makes sense for your vehicle and how you use it.
