【ZONOTONE Royal Spirit SP-1 (1.5m)｜Speaker Cable for Car Audio】

I want to add a bit more information and detail to the sound in my car audio system. I want to perceive the positions of vocals and instruments naturally. But I’m not at the point where I want to replace the speakers or amplifier right away. If this sounds like you, the ZONOTONE speaker cable Royal Spirit SP-1 (1.5m) is worth considering.

Speaker cables aren’t the most noticeable parts, but they are an important component that transmits the music signal from the amplifier to the speakers. By re-evaluating the cables, you may be able to feel changes in the sound’s outline, subtle expressions, and how the soundstage spreads. You can aim for impressions such as the vocals you normally listen to sounding a little closer, each instrument’s position becoming easier to pinpoint, and the sound not only coming from right next to the speakers, but connecting naturally throughout the entire cabin.

Royal Spirit SP-1 is a new-concept speaker cable developed to commemorate the 10th anniversary of the company’s founding. It uses a new conductor that combines four types of materials, including ultra-high-purity 7N class Cu, HiFC, and PCUHD. By combining the characteristics of each material, this model is designed to maintain the amount of audio information while bringing out a sense of openness and depth.

In particular, after installing a new speaker system or having an amplifier/DSP setup performed, there is value in considering a cable replacement if you want to refine the overall system one more step. Changes in sound are not judged only by their magnitude; they show up in the fine details you notice within the music you listen to every day—such as the expressions of the vocals, how the reverb tail remains, and how instruments overlap. The longer you drive and listen to your favorite music, the more enjoyable you may find these natural kinds of changes.

However, replacing speaker cables doesn’t always produce the exact same result. In addition to the combination of speakers, amplifier, DSP, and the OEM audio, the final outcome will also vary depending on how the cables are routed, how the connection points are handled, and the challenges your current system is dealing with. In some cases, it may be better to review adjustments or other parts first, rather than spending money on cables.

At LOGON, we don’t decide on products first. Instead, we think things through by confirming what you’re dissatisfied with in your current sound, what kind of music you listen to most often, and how much has already been done to your current system. If I were advising you, I wouldn’t recommend replacing cables just because they’re “good.” I would look at your vehicle and the entire system, then work on the parts where spending money truly makes sense.

Royal Spirit SP-1 (1.5m) is a speaker cable suited for people who want to shape the soundstage spread and depth a bit more naturally, who want to further fine-tune the results after replacing speakers, and who want to enjoy music carefully inside the cabin. While listening to your current sound, let’s decide together whether a cable replacement is the right approach—or if another method would be better as well.
