D30/S QRD Diffuser Panel

D30/S QRD Diffuser Panel


By changing the depths and breadths of each well, the QRD design allows the diffusion range of the panel to be altered.

As such, even at its smallest size, the D30 is able diffuse effectively from 571Hz – 1142Hz and extensively to 5548Hz. This allows it to bring clarity to the upper-mid frequency range which helps articulate sounds like vocal presence.
