【ZONOTONE Grandio SP-1 (5.5m)｜Speaker Cable That Adds Body and Soundstage Width to Your In-Car Audio】

Designed for people who, while listening to their car audio, feel that they want “a little more body in the sound,” “more presence from vocals and instruments,” or “a soundstage that feels wider toward the front.”

Grandio SP-1 (5.5m) is a next-generation Grandio-series cable that combines five types of conductors, including ultra-high-purity 7N-class Cu, HiFC high-performance pure copper wire made with a new material, high-purity oxygen-free copper wire PCUHD, modern tinned high-purity copper, and high-purity oxygen-free copper OFC.

In terms of sonic character, it’s aimed more at delivering a rich, dense sound than at being thin and lightweight. When you play music, thickness is added to the core of the vocals and the outlines of instruments, making it easier to perceive tonal shading and a sense of power. In addition, it is also crafted with soundstage width and depth in mind, so it’s well-suited for those who want to feel the entire stage as larger—not just lineup sounds in front of the speakers.

In your favorite vocal tracks, facial expressions in the voice are easier to convey, and with live recordings you can enjoy the impact of the performance and the spaciousness of the sound. Even with songs you already listen to all the time, the change in sound body and forward presentation makes it interesting in a way that encourages you to listen again.

However, speaker cables won’t produce the same result just by replacing the product. The final impression will vary depending on compatibility with your speakers and amplifier, cable routing, how the terminal sections are handled, and the overall balance of your existing system. To make the most of the cable’s strengths, it’s important to consider not only the cable itself, but also where and how it’s connected.

At LOGON, we will make suggestions—including whether the Grandio SP-1 will suit your setup or whether it would be better to review other parts first—while confirming your speakers, amplifier, and your current audio concerns. This is a speaker cable well worth consulting about if you want to achieve solid sound body and scale, and also if you want to refine your entire system one step deeper.
