Grandio SP-1 (3.5m)

A premium speaker cable for enjoying your car’s sound more richly and more comfortably.

【Zonotone Grandio SP-1 (3.5m)|Speaker Cable That Adds Body and Soundstage to Your Car’s Audio】

While listening to your car audio, do you ever feel like “even if I turn the volume up, I don’t get the impact I expected,” or that you “want a bit more presence from the vocals and instruments”? Even when you replace the speakers or amplifier, you may not be able to fully bring out the strengths of your entire system unless you also reconsider the cables that deliver the signal.

Zonotone Grandio SP-1 (3.5m) is a speaker cable that combines five materials, including ultra-high-purity 7N-class Cu, as well as a new-material 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. By hybridizing these materials, the design is focused not only on adding sonic thickness and force, but also on expanding the soundstage and enhancing the sense of depth.

When incorporated into a system, you can experience more than just a sense of impact as if the sound is pushed forward—you may also find it easier to perceive the positioning relationships of vocals and instruments, or hear the music as if it gains more density overall. Even with songs you already listen to all the time, this cable has the potential to let you notice differences in sound density and stage feel. It’s well suited not only for those who prefer powerful sound, but also for anyone who wants to enjoy a live-like sound in their car.

However, speaker cables won’t necessarily produce the same results simply by swapping them. The final impression will vary depending on compatibility with your speakers, amplifier, DSP, existing wiring, and the vehicle-side system. It’s important to think not only about which cable to choose, but also about where to use it, how to route the wiring, and how to handle the terminal processing.

At LOGON, we make proposals while confirming your vehicle’s system configuration, the music you usually listen to, and the direction of sound you want to achieve—so that we can advise whether there is a real meaning in using the Grandio SP-1 (3.5m). We won’t prioritize simply adding expensive parts; instead, we work together to organize where you can make changes in your current system that are more likely to produce noticeable improvements.

If you want to rethink the foundation of sound in combination with replacing your speakers or amplifier, or if you’d like to add an extra layer of thickness and soundstage to your current system, please feel free to consult us. We’ll refine the setup while keeping the overall balance in mind, so that the time you spend listening to music inside the car feels richer and like a stage that expands forward.
