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.
