HOFA Diffusor

HOFA Diffusors are effective acoustic elements to optimise room sound.

They can be used wherever the best possible room acoustics are required, for example in recording studios, home cinemas or home-recording environments.

The HOFA Diffusors are manufactured by hand, in close cooperation with a sheltered workshop (Lebenshilfe, Germany).

Sounds good

The two-dimensional HOFA Diffusors ensure a vivid and controlled room sound. Diffusors help you to achieve a better and more natural sound, wherever music is played or recorded.

Our Diffusors are made of birch plywood, and they look as good as they sound. Excellent workmanship and the natural materials make HOFA Diffusors optically appealing in any room.

HOFA QR-Diffusor

Four become one

For perfect and symmetrical diffusion in your room, you can easily combine four diffusers into one large QR diffuser.

The HOFA QR-Diffusor scatters sound waves effectively and the room sound becomes more balanced and refined.

Fabric cover for HOFA Diffusor

HOFA Diffusor natur only 69,90 €
  • Dimensions: 50 cm x 50 cm x 11 cm
  • Compatible with the HOFA Frame
  • Available in 6 different colours
  • No influence on the acoustic effect of the diffusor

Choose your own look

The fabric covers allow you to colour-match your diffusors to the HOFA Absorbers and Basstraps – or combine different colours entirely to your liking. The thin fabric of the cover does not affect the acoustic properties of the diffusor.


Easy fix

Simply cover your HOFA Diffusor with the fabric cover and tie the ribbon on the back. Due to the stretchy fabric, it covers the diffusor wrinkle-free. The cover is washable and can be ironed.


Combination is key

Absorption & diffusion

In many cases it’s recommended to use HOFA Absorbers in combination with our Diffusors. In rooms where you listen to music (control rooms, hi-fi rooms, home theaters, …) absorbers and basstraps are important elements of a balanced sound.

Live end – dead end: LEDE

The LEDE concept is the ideal solution to achieve a perfect listening environment: sound energy is reduced with HOFA Absorbers and Basstraps (Dead End) and sound is scattered at the rear end of the room with HOFA Diffusors (Live End).

Versatile and flexible

Absorbers and Diffusors can be combined as desired in the HOFA Frame. Mounting is very simple, both on walls and the ceiling.

What can HOFA Diffusors improve?

Diffusors ensure lively room reflections.

HOFA Diffusors help you to realise professional and natural room acoustics. They improve signal location, especially in the mid and high frequencies and prevent annoying flutter echoes. Thus, instruments, vocals and loudspeakers can show their full potential.

In the live room

HOFA Diffusors ensure a natural and balanced room sound when combined with a sufficient number of absorbers. We especially recommend diffusors when recording acoustic instruments like guitars or percussion.

In the control room

Diffusors are used in control rooms in addition to absorbers in order to achieve a balanced mix of absorption and lively room sound and to eliminate annoying flutter echoes on smooth surfaces.

How many do you need?

One to four modules are ideal for the near field. They ensure balanced acoustics during the recording of instruments.
How many modules are actually needed in your room depends on the geometry, interior design and intended use of your room. If you have any questions about the number of modules or the installation, please contact us.


Sustainability & social manufacturing

Climate neutral acoustic modules

Working environmentally responsible has always been an important part of our corporate culture. Therefore, we compensate all CO2 emissions that are generated at HOFA and cannot be avoided by supporting a climate-positive project certified to the highest standard. At HOFA-Akustik, for example, we compensate for the entire production and delivery of HOFA acoustic modules, every job including the commutes of our employees, the complete infrastructure with office and warehouse, and much more.

Short transport routes & close cooperation with local workshop “Lebenshilfe”

All HOFA acoustic modules are produced in Germany – most of them at “Lebenshilfe Bruchsal-Bretten”, just a few kilometres away from our offices. This way, we support local workshops for people with disabilities, which have been working with us for over 15 years and supply us reliably with high-quality acoustic modules. All HOFA products are then packed and shipped from our own warehouse.
