【ZONOTONE Grandio SP-1 (4.0m) Speaker Cable | Add Body and Soundstage to In-Car Audio】

For those who want to enjoy car audio sound even more deeply, ZONOTONE’s speaker cable Grandio SP-1 (4.0m).

When you replace speakers or add an amplifier and the sound starts to improve, the next thing that often comes to mind is the cable that delivers the signal to the speakers. You may want a bit more body in the sound, clearer vocal presence up front, or a wider sense of soundstage. In such cases, it’s worthwhile to reconsider the overall system balance—including the cables.

Grandio SP-1 is a speaker cable that combines five types of materials, including ultra-high-purity 7N-class Cu, high-performance pure copper wire HiFC, high-purity oxygen-free copper wire PCUHD, tin-plated high-purity copper, and high-purity oxygen-free copper OFC. Designed to take advantage of the characteristics of each material and aim for a rich, dense presentation.

When you listen to music, you’ll find it easier to sense more impact from the low to mid frequencies and added thickness in the contours of the sound. If vocals or instrument tones feel thin, this cable makes it easier to add punch that spreads forward while firmly supporting the core of the sound. The design also considers expansion of the soundstage and a sense of depth, making it suitable for those who want a lifelike presence—as if you’re listening from within the stage—even with your everyday tracks.

That said, replacing a speaker cable doesn’t always produce the exact same result. Depending on the character of your speakers and amplifier, your current wiring, the connection method, and how the sound comes together inside the car, compatibility can vary. If I were choosing, I wouldn’t base it only on the cable’s standalone performance; I would check what sound your current system is producing and what you want to extend before making a decision.

At LOGON, we organize together which parts are more likely to show improvement from a cable swap—while asking about your vehicle model, the audio equipment you use, the music you listen to most often, and your preferences for volume. It’s important to have the installation planned with care so that after it’s fitted, you can enjoy your music in a comfortable, satisfying way—down to routing the wiring and finishing the connections.

If you want to add more body to your sound, draw even more out of your speaker and amplifier performance, or enjoy not only punch but also width and depth, consider adding the Grandio SP-1 to your shortlist. While checking your current sound, we’ll think together in a sensible, no-nonsense way—also considering whether a replacement is truly worthwhile.
