【Zonotone Royal Spirit SP-1 (3.0m)｜Speaker Cable for Car Audio】

For Those Who Want to Revisit Soundstage Spread and Depth

Even after replacing your speakers and amplifier, you may feel that the way the sound “comes together” or spreads could be improved a bit more. In such cases, it’s worth looking not only at the equipment, but also at the speaker cable that delivers the music signal to the speakers.

Royal Spirit SP-1 (3.0m) is a speaker cable for car audio developed to commemorate Zonotone’s 10th anniversary of its founding. It uses a hybrid conductor that combines four types of materials, including ultra-high-purity 7N-class Cu, HiFC, and PCUHD.

Swapping the cable doesn’t mean every car will produce the exact same sound. However, when used while considering the balance of the entire system, it can be a good starting point for rethinking soundstage spread and depth, as well as the positional relationship between vocals and instruments.

For Those Who Want to Enjoy Your Usual Music a Bit More Naturally

The sound seems to gather at the speaker positions, the vocals are too close, and it’s hard to make out how the instruments are arranged. If you have concerns like these, changing the speaker cable can be one of the ways to improve the sound.

Royal Spirit SP-1 (3.0m) is a cable suited to those who want to focus not only on increasing the amount of audio information, but also on the sense of spread when listening to music inside the car and the expression of the performance space.

When you play the songs you usually listen to, you may find that the instrument sounds around the vocals—and the connection between sound and sound—feel natural. Choosing the cable with those changes in mind may help you feel more clearly the value of a cable replacement.

Just as Important as Choosing the Cable Is How It’s Installed

Speaker cables aren’t simply a matter of picking the product.

Depending on how it’s paired with your speakers and amplifier, how the wiring is routed, how the connection sections are handled, and the balance with your existing system, the overall impression of the finished sound can change. Even if you use the same Royal Spirit SP-1 (3.0m), where you incorporate it and how you organize the system as a whole are critical.

If it were me, I wouldn’t decide only on the cable first. I would check your current speakers and amplifier, the music you typically listen to, and the complaints you’re currently experiencing before making a decision. There are cases where it makes sense to consider the cable replacement together with a speaker upgrade or the addition of an amplifier; and there are also cases where revisiting the cable first makes it easier to align the system’s overall direction.

At LOGON, you can consult us not on the assumption that you will add products, but also including whether a cable replacement is an effective stage for your current vehicle. We finish carefully all the way through the installation and connection sections, and while confirming the sound after installation, we think together about the direction that lets you enjoy listening comfortably in the car.

If you’d like to revisit soundstage spread or depth, or if you want to know whether replacing the speaker cable will suit your current system, please feel free to consult about Royal Spirit SP-1 (3.0m). Rather than treating the product as a standalone item, we’ll organize the way to choose—something that’s less likely to need changing later—while looking at your vehicle and the entire system.
