Sound diffuser system
OptiDi is an acoustic diffuser designed for specific performance goals. It gives interiors a distinctive character, combining minimalist aesthetics with excellent acoustic properties.
The system is made of specially profiled aluminium to provide sound diffusion in the mid and high frequency ranges, while also absorbing low frequencies. When designing the shape of OptiDi, our key objective was to achieve high sound diffusion efficiency with the smallest possible panel depth.
Every millimetre mattered to us.

Details
OptiDi system diffuses sound in mid and high frequencies, most effectively as a combination of positive and negative modules. Due to internal filling and variable slots’ width, bass absorption may be adjusted to a particular frequency of choice. OptiDi is usually used on walls but it can be designed for ceilings or as a portable panel as well.
