Grandio AC-1 (4.5m)

Refine the foundation of sound, carefully starting from a single cable.

【ZONOTONE Grandio AC-1 (4.5 m) | Interconnect Cable for Car Audio】

ZONOTONE’s interconnect cable Grandio AC-1 (4.5 m), designed for those who want to further refine their car audio sound.

Cables are often thought to cause changes that are difficult to notice, but in order to properly convey information from the entire system, the signal path itself is also an important part. Centered on ultra-high-purity 7N-class Cu, the Grandio AC-1 combines five materials: the new high-performance pure copper wire HiFC, high-purity oxygen-free copper wire PCUHD, tin-plated OFC, and high-purity oxygen-free copper.

This is a cable aimed not only at emphasizing impact and power, but also at making it easier to perceive sound’s leading edge and fine details. It is designed to naturally convey vocal and instrument placement, as well as the depth of the recording space. It’s for anyone who wants to enjoy their usual music a bit more three-dimensionally and a bit more vividly.

A length of 4.5 m is convenient depending on the layout of your in-car equipment. At the same time, how you handle any excess cable also affects the final finish. Rather than simply swapping it out, installing while checking your current system configuration, the placement of your components, and cable routing relative to other cables will help you achieve a clean result—including in appearance.

In car audio, the impression changes not only with the performance of the cable by itself, but also with how it’s combined with the head unit, DSP, amplifier, and speakers. If I were choosing, I’d consider the overall sound direction and the balance of your current system, and think about replacing the parts where you’re most likely to feel the effect. Let’s choose together, including whether the Grandio AC-1 suits your current car.
