“Driven by Passion. Perfected by Hand.”

Nothing but the best for your car.

This isn't just high-end car audio. This is high-end car hi-fi.

For over 25 years, Zelos has chased one thing—pure sound. Born from the legacy of Abyss-Zelos, we don’t follow the trends of car audio. We forge our own path. Every amplifier, every speaker, every circuit we create is a deliberate rebellion against mediocrity.

We believe true performance isn’t mass-produced. It’s crafted—painstakingly, relentlessly, by hand.

What Makes Zelos Different?

Dual-Circuit Mastery:

While most brands pick one path—Voltage Feedback or Current Feedback—we combine both for ultra-precise control, fast response, and a holographic soundstage.

Home Hi-Fi DNA, Reimagined for the Road:

Inspired by the finest home systems, our amplifiers boast oversized power supplies, precise bias calibration, and Class A/AB hybrid designs that recreate music as it was intended.

Only the Finest Components:

WIMA film capacitors, Burr Brown op-amps, VISHAY FETs, hand-soldered gold terminals—every detail serves a single goal: perfect sound.

100% Handbuilt. 100% Repairable.

Built to last decades. Easy to maintain. Never disposable.

Zelos x Concerto

Where Passion Meets Precision

A collaboration born from obsession with perfection.

At Zelos, every amplifier is built by hand. Every speaker is tuned by ear. For decades, we’ve defied trends and rejected shortcuts—because true sound takes time.

Concerto understands that. More than a distributor, we are curators of experience. With deep roots in Indonesia’s car audio community, Concerto shares our belief that quality is sacred—and sound should move you.
