ABOUT US
Who We Are
Seruniaudio is a professional audio brand developed by PT Seruni Karya Indonesia, a leading audio equipment manufacturer based in Yogyakarta, Indonesia. We specialize in high-quality sound reinforcement solutions, with a strong focus on designing and hand-building professional-grade microphones for musicians, creators, and sound professionals.
Our journey began in 2015 with the launch of the SEM-01, a compact, clip-on electret condenser microphone designed specifically for acoustic instruments. Built by hand in our Yogyakarta workshop, the SEM-01 redefined how musicians in Indonesia amplify and record their instruments—offering a practical, high-fidelity alternative to bulky condenser and dynamic microphones.
​
In recognition of its innovation and design excellence, SEM-01 was awarded the Good Design Indonesia Award in 2017, marking a milestone for locally made professional audio gear.


Our Innovation & Progress
In 2020, Seruniaudio introduced the SEM-02, a next-generation microphone designed to offer enhanced durability, wider usability, and superior sound performance. Whether it’s for live performances, studio sessions, voice-overs, film sound design, or on-location recording, SEM-02 delivers natural, clear audio with minimal setup.
Despite its small size, the SEM-02 is built to perform with power and precision—trusted by musicians, engineers, and content creators alike.
In 2023, we launched the MKS-14, a stage-ready microphone system designed for ensemble and orchestral performances. This model was honored with the Good Design Indonesia Award 2025, strengthening Seruniaudio’s position as an innovator in professional audio solutions.
Our Commitment
At PT Seruni Karya Indonesia, we are committed to pushing the boundaries of audio innovation through our Seruniaudio brand. Every product is designed with care, hand-assembled in Yogyakarta, and tested to meet the demands of professionals around the world. We exist to empower creators with tools that sound great, perform reliably, and are built to last.
