QRD Diffuser


Creating a sense of spaciousness and aesthetics for your space by efficiently dispersing sound waves across the frequency range.


Timber Acoustics Quadratic Diffuser is made up of wells of differing depths that cause a combination of phase shifts that diffuse reflected sound. They’re used to suppress reflections in the listening atmosphere, particularly from rear walls and first-reflection points.

They are based on prime numbers, each of which has a special frequency response. The QRD sound diffuser is made of a series of parallel caissons with column variation depth. The product has a strong sound diffusion effect and reduces reverberation time significantly. It helps in diffusing energy around 484 Hz – 2260. This acoustic diffuser has a series of wells or troughs of varying depths into which sound energy is bounced around within the well and returns in a smaller version of itself spread out in a 180 degree, fan-like array of energy.

– It efficiently disperses sound waves through a broad frequency range owing to the vast number of small wells.
– Boasts low frequency diffusion which is not achievable with lightweight plastic diffusers.
– Dense and Rigid.
– Eliminates standing waves and flutter echoes.
– Adds a sense of air and retains natural ambience.
– The diffusers are made of a rigid structure for easy installations on walls.
– Mounts are provided with the QRD Diffuser.
– N7 Prime Numbered diffuses energy around 484 Hz – 2260 Hz.
– New Zealand Pinewood

Revolutionize Your Space with Our Innovative Acoustic Solutions

By creating a more controlled and balanced sound environment, acoustic panels also enhance the emotional impact of music. For example, in a home theatre or listening room, acoustic panels can help to create a more immersive experience, allowing music to fill the room without any unwanted interference or distortion.

A perfect solution for creating a quiet environment

Timber Acoustics panels and diffusers are a versatile and effective solution for creating a quiet environment in any space. By controlling the way sound waves behave within a room, acoustic panels as well as diffusers can help with noise reduction, sound proofing, increase privacy, improve speech intelligibility and create a more comfortable and functional space for work, relaxation, or entertainment.

Experience crystal clear sound every single time
Whether it’s a recording studio, a home theatre, or a conference room. Echoes and reverberations can create unwanted noise pollution, making it difficult to record your mix, hear and understand speech, music, or other audio content clearly. Acoustic panels help to control the way sound waves behave by absorbing or diffusing unwanted echoes and reverberation. This helps to create a more accurate and balanced sound environment.
