【Grandio SP-1(4.5m)｜Zonotone speaker cable that brings out sound thickness and spaciousness】

When you want to make your car audio sound even more solidly refined, it’s worth looking not only at the speakers and amplifier, but also at the speaker cable that delivers the music signal to them.

Grandio SP-1(4.5m) is a Zonotone speaker cable made by combining five different materials: ultra-high-purity 7N-class Cu, the new high-performance pure-copper wire HiFC, high-purity oxygen-free copper wire PCUHD, modern tin-plated high-purity copper, and high-purity oxygen-free copper OFC.

In terms of sonic character, rather than simply emphasizing fine details, it’s suited to those who want to add thickness to the overall music and bring out the presence of vocals and instruments. It adds shadow-and-highlight contrast and richness in the sound, as well as a forceful, push-forward sense of power—making it easier to perceive the stage’s spread and the depth both front-to-back.

It’s a cable worth considering if you want your favorite vocals to feel closer, want to enjoy rock or live recordings with impact, or feel that the sound is somewhat flat and leaves you wanting more. Even with songs you already listen to often, you may notice changes in the sound’s thickness and in how instruments overlap.

However, speaker cables don’t produce the same result just by replacing them. What you hear will change depending on the vehicle’s system configuration, the combination with the speakers and amplifier, how the cable is routed, terminal processing, and the finishing of the connection points. Even if you choose an expensive cable, if the installation and adjustment don’t match your car, its advantages may not be fully realized.

At LOGON, we don’t recommend a product as a standalone item—we work together to consider what replacing the cable means, while checking where changes in your current system are most likely to produce an effect. Taking your sound direction and budget into account, we’ll propose a configuration that won’t be a burden.
