【ZONOTONE Grandio SP-1 (3.0m)｜Speaker Cable that Brings Out Dense Power and Spaciousness】

When you listen to your car audio, don’t you ever feel things like, “Even if I turn it up, it still sounds somehow thin,” “I want a bit more presence from the vocals and instruments,” or “I swapped the speakers, but the sound doesn’t change as much as I expected”?

ZONOTONE Grandio SP-1 (3.0m) is a carefully crafted speaker cable designed for those who want to bring out the speaker’s true expressive potential.

It uses a hybrid structure unique to the Grandio series, combining five materials: ultra-high-purity 7N-class Cu, high-performance pure copper wire HiFC using a new material, high-purity oxygen-free copper wire PCUHD, modern tin-plated high-purity copper, and high-purity oxygen-free copper OFC.

In terms of sound character, rather than simply brightening and emphasizing fine details, it tends to make the thickness and density of the sound easier to perceive. Vocals are likely to gain presence, and sounds such as those from guitars and pianos also become easier to follow not as flat layers, but with a clearer sense of positional relationships front-to-back and even the lingering decay. It’s suited to those who want to maintain energy from the low end through the high end, while also seeking a wider soundstage and greater depth.

If you want to enjoy the kind of impact as if the performance were right in front of you, or if you want to experience the music you always listen to one level deeper, I think this is a cable where you’ll feel the value of the upgrade.

However, speaker cables don’t produce the same result just by replacing the product. Depending on the configuration—such as the vehicle’s factory system, speakers, amplifier, DSP, and more—the direction of which cable suits your setup can change. How the sound coheres also varies with wiring routing, connection methods, and the combination with each component.

At LOGON, we don’t recommend the Grandio SP-1 (3.0m) as a standalone item. Instead, after confirming what kind of music you listen to in your car and where you’re dissatisfied with your current system, we work with you to consider what parts are truly worth replacing. Whether you’ve already upgraded your speakers and amplifier—or if you’d like to raise the thickness and realism of the sound a bit more—please feel free to consult us. (3.0m)
