Great acoustics on a budget

We have optimized our designs so they are fast and easy as possible to make with really low material cost.


Open Source

The best solutions always arise when communities work together. The most efficient way to maximize this is to share knowledge.


Best sound treatment

We share the most efficient designs in the market. The Ultrafusor is more efficient than a standard PRD diffusor, and our absorbent panels work great for frequencies as low as 100 Hz.
