OptiDi is one of the kind diffuser giving your interior a unique aesthetics. It combines philosophy of minimalistic design and great acoustic properties. Its specific shape made of aluminium provides sound diffusion combined with efficient absorption in a lower frequency range. OptiDi providing a great visual effect and outstanding acoustical performance.
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.
