The QRD 1D 407 diffuser is an exceptional acoustic panel. It uniformly distributes sound in the mid and mid-high frequency range. It is a classic QRD Schroeder diffuser based on the prime number 7, providing outstanding sound diffusion capabilities. The diffuser is made entirely of natural hardwood of the highest quality, which makes it eco-friendly and provides superior acoustic properties.
The QRD 1D 407 diffuser has several benefits that make it a popular choice. It effectively eliminates multiple sound reflections from walls, reduces reverberation, and prevents the comb filter effect. This results in a more sonically pleasing and spacious-sounding room that is perfect for music recording, podcasting, or any other audio-related application.
The QRD 1D 407 diffuser works effectively in a wide frequency range. Because of its relatively narrow and deep shafts, it transforms unwanted reflections into a sonically pleasing diffuse sound field. Having a dispersion range of ~ 500 to 3000 Hz, makes it suitable for a wide range of applications.
Mounting the diffuser is easy with the hangers on the backside of the panel. The installation process is hassle-free, and the diffuser can be easily removed and repositioned as needed.
In conclusion, the QRD 1D 407 diffuser is an effective and environmentally friendly acoustic panel that provides excellent sound diffusion capabilities. Its ability to eliminate sound reflections, reduce reverberation, and prevent the comb filter effect makes it perfect for optimizing rooms used for music recording, podcasting, or any other audio-related application.
