A Quest to build the Perfect Sound

Uncompromising technology for the perfect sound experience.



One & Only

The principle of this technology is like noise-canceling headphones, but for a large room. The core principle of the hardware is very simple. We vibrate the surface of the plate with a sound wave 180 degrees out of phase, which is opposite to the wave generated by the sound source in the room.

Our hardware is controlled by the software system. When we install our system, we perform a 1-hour calibration and a 1-hour fine-tuning. During this time, the AI system in the DSP learns what the sound characteristics of the room are. It learns the different frequency concentrations in different parts of the room and other data. So when a frequency band comes from the main audio system, the DSP sends the correct 180-degree frequency band for each panel. In this way, we minimize and control the noise and echo in the room and create the best acoustics in the middle listening area.


Learning from the Best

Clear and unmistakable lines as well as distinctive wooden membrane make Shion active acoustic systems not only of musical but also of visual art. 

Shion's design team has been working side by side with renown designers and artists such as Zaha Hadid.

According to Shion's design philosophy, wood is much more than just a visual element. At first glance, it stands for the high value and durability of a product. This is why several weeks of development are invested in a seemingly simple detail such as the orientation of wooden fibers. It is designed to give the most natural feel to the person lucky enough to experience this outstanding quality first hand.


Passion for Material

We value local craftsmanship. From the first design sketch to prototypes, all the way to the final product: Every component marked with the Shion name has been completely developed in-house and assembled manually by highly qualified technicians. This is how we create icons of the high-end audio universe.



German Engineering

To achieve absolute sound quality, we combine state-of-the-art technology, the best electronic components and craftsmanship. Prior to assembly, we select only the best components that meet our tightly defined tolerances.

Over 300 computer-assisted measurements are performed before and after installation into our active acoustic modules. A component only enters the final test phase if the measurements show no deviation. Afterwards, the device has to pass our manual Shion hearing test before shipping.


Cutting Edge AI

Even though technology is capable of ever more, we believe that its application should not be a mystery. After all, we want the attention to be fully dedicated to the enjoyment of music.

This is why Shion software system use powerful Artificial Intelligence to perform real time calibration and adjustments to the performance of the system. Our listeners shall not worry about anything. Just sit back and enjoy the perfect sound.
