Sound diffuser panel
OptiDi Panel is a compact acoustic diffuser with a wide range of applications. Its unique shape and colour bring life to any interior, giving it a distinctive character by combining visual appeal with acoustic performance. Precisely formed from aluminium, it is available in two profiles and two thickness options, providing sound diffusion in the mid and high frequency ranges, with optional low-frequency absorption.
When designing the shape of OptiDi, our key objective was to achieve high sound diffusion efficiency with the smallest possible panel thickness.
Every millimetre mattered to us.
A Master of the Background
OptiDi Panel does more than diffuse sound – it can also take centre stage in an interior arrangement.
At Kraków’s Variete Theatre, it proved that acoustic performance and scenic presence can go hand in hand.
Golden Hall
of the Kraków Philharmonic
OptiDi Panel was used as an acoustic treatment supporting sound control in this intimate concert space, without interfering with the representative character of the interior.
Extended Low-Frequency Control
OptiDi Panel can be complemented with a rear absorbing module, extending its performance to include low-frequency control.
