Product Description

Nankarrow QuadraFuse™ QD1 is a two-dimensional diffusion panel that is best applied to walls or ceilings, providing multi-reflection on both vertical and horizontal planes in sound critical spaces. It performs on mid and high frequencies, brightening and clarifying sound.

Don’t risk missing results by simply putting random blocks in a series that are not calculated, as that will not give even acoustic diffusion. Make the room sound bigger with TRUE diffusion of high frequencies with our precision-cut, 23-root, two-dimensional Quadratic Diffusor.

So, let us explain Acoustic Diffusion.

What is diffusion?

While absorption is vital for any room an area that can’t be ignored is diffusion. Diffusion is the even spreading of sound waves from a direct source. So, if you have a small space diffusion can give the idea of a room being larger than it actually is by providing increased natural ambience.  By having no absorption or diffusion installed in a space speech intelligibility is reduced and sound quality is degraded and while absorbent materials will help a great deal in solving that dedicated well designed diffusion such as our Nankarrow QuadraFuse™ acoustic diffusor will be much more effective.

Nankarrow QuadraFuse™ Acoustics diffuser panels gives your recording studio or listening environment a sense of spaciousness in your music by addressing the above issues without deadening the room too much. Sound diffusers scatter sound across two planes: horizontal (left & right) and vertical (up & down), which is called acoustic diffusion. This two-dimensional scattering broadens the soundscape and makes a room sound larger.

Nankarrow QuadraFuse™  diffusers you can be sure that your speakers or monitors don’t have a bommy sound , with an ill-defined mid-range, an aggressive high end and an uneven bass response  where some notes boom out and others seem almost to vanish.

Nankarrow QuadraFuse™ can be used in control rooms, broadcast studios, live rooms, home theatres – anywhere a range of instruments and voices are recorded or heard, rehearsal rooms and other performance spaces.

Nankarrow QuadraFuse™  is made from from high quality Taiga Spruce Wood  form Russian Snow Forest. It’s instantly alluring design results from unique research based on the acoustic properties of the wood. Nankarrow QuadraFuse™  to act as a diffuser, letting you tame reflections without rendering your room dead.

    I received the Diffuser in approximately 15 days in perfect condition, as soon as it was installed I could notice the difference of sound in my listening room. Reasonably priced and worth being purchased.

  3. Great Product very effective

    Rajesh Shetty

    Like all Nankarrow products,this item is well made, looks attractive and is reasonably priced.
    I bought several of these diffusers to maintain a good balance of diffusion, as suggested by auralexchange team to compliment the Nankarrow absorbers I also purchased. Collectively, they make a huge improvement to the acoustics in my studio.
    As an added bonus I can hold my car keys in one of the cubby holes..very handy!

  4. It's just beautiful

    Nandan Kumar

    Deducted one star for late delivery – took almost 15 days because it had to be imported specially. But it’s really an amazing quality and very heavy so you will need strong fixing mechanism to put it on the wall or especially ceiling. Weighs 9-10kg almost. Genuine product.
