DiffusersSilentical QRD Acoustic Sound Diffuser
The Silentical QRD Acoustic Sound Diffuser uses a mathematically derived well sequence to scatter sound with precision. Instead of absorbing energy, it redistributes it. The room stays vibrant while harsh reflections and flutter echo disappear.

The 1D model (SI-QRD-001) uses rubber solid wood in a 600 x 600 x 100 mm module; a 2D version (SI-QRD-002) is available in 1200 x 600 x 100 mm and 600 x 600 x 100 mm in solid oak, fir, or paulownia. Both carry a standard environment-friendly finish paint, national standard E1-level environmental performance, B1 flame-retardant performance, and full-frequency diffusion.
The reference choice for recording studios, home theaters, listening rooms, rehearsal spaces, houses of worship, and performance venues where accuracy matters. For complex noise problems, Silentical's acoustical consulting and noise study services measure your space first, so the treatment plan targets the actual problem instead of guessing.
