Crafted from high density solid wood and PU paint, this diffuser brings the precision of a Quadratic Residue Diffusion (QRD) mathematical design.

Grooves with varying depths facilitate uniform diffusion across a spectrum of frequencies.

This not only mitigates standing waves and flutter echoes but also addresses other anomalies that may compromise sound quality, simultaneously giving us the perception of a more spacious room.

Optimum diffusion range: 430-861 Hz.
