【Royal Spirit AC-1(4.5m)｜High-Purity Audio Cable to Refine Soundstage and Depth in Car Audio】

For those who want to draw out a bit more—more information and wider spread—from their car audio, here is the Royal Spirit AC-1(4.5m).

This cable combines four types of conductors—ultra-high-purity 7N-class Cu, high-performance pure copper wire HiFC, high-purity oxygen-free copper wire PCUHD, and high-purity oxygen-free copper OFC—in a proprietary balance.

In an orchestral symphony, it helps you more easily perceive the positioning of instruments and the depth of the sound. In big band jazz, it’s designed so that each instrument doesn’t overlap too much, aiming instead for a spread that lets you look across the entire stage. It’s for those who don’t just want sound made flashy, but want to enjoy a wide sense of soundstage that feels like the music is wrapping around you inside the car.

Car audio doesn’t always change in the same way just by swapping cables. It’s important to consider compatibility with the entire system, including your speakers and amplifier, the DSP configuration, the cable length and routing, and even terminal processing.

If it were me, I’d use the cable where its effects can be maximized, after checking your current audio concerns and the music you listen to most—rather than deciding based on the cable alone. If you’re going to replace it, it’s less likely you’ll regret it if you align the direction together while also keeping an eye on the sound after installation.
