How diffusers and absorbers work
Absorbers and diffusers have different functions, but both are important for the acoustics of Hi-Fi systems. Let's take a look at how they work and when to use them.
Absorbers work on the principle of sound energy absorption . They are made of porous materials such as mineral wool, polyurethane foam or special acoustic fabrics. When a sound wave enters the absorber, it penetrates the material and some of its energy is converted into heat due to friction. This process is most effective in the mid-range (500–2000 Hz) and high-frequency (2000–20000 Hz) ranges.
Diffusers , on the other hand, disperse sound waves in various directions without losing energy. Their surfaces are complex shapes, with depressions and protrusions of varying depths. When a sound wave hits the diffuser, it is reflected in different directions, thus creating a uniform sound field throughout the room. Diffusers work most effectively in the frequency range from 500 Hz to 4000 Hz.
When to use absorbers
Absorbers are useful in the following cases:
- To control first reflections – when sound waves from side walls reach the listener within 5-15 milliseconds after the direct sound.
- To eliminate flutter echoes between parallel walls, which can give the sound a metallic tinge.
- In living rooms , where the reverberation time exceeds 0.4–0.6 seconds.
When to choose diffusers
Diffusers are perfect for:
- For rear walls behind the listener, where absorbers could reduce the spatial sensation too much.
- For ceilings , to reduce strong reflections from above.
- For side areas where reflections need to be controlled but not completely eliminated.
It is important to understand when and how to use these solutions, as it directly affects sound quality.
Material and construction features
The effectiveness of absorbers depends on the density and thickness of the material. Thinner panels (2.5–5 cm) absorb high frequencies, while thicker absorbers (10–15 cm) are effective in the mid-range. To control low frequencies, special bass traps are used, which are often triangular in shape and installed in the corners of the room.
The effectiveness of diffusers depends on the complexity of their geometry and depth . Sequential diffusers, based on mathematical formulas such as the Schroeder sequence, ensure uniform sound dispersion. The depth of the diffuser should be at least 1/10 of the wavelength of the lowest controlled frequency. Properly selected designs improve stereo imaging and sound clarity - which is very important for Hi-Fi systems .
Compatibility with Hi-Fi systems
For Hi-Fi systems, it is essential to maintain a natural timbre balance . Too many absorbers can “kill” the sound and reduce the sense of dynamics. The best solution is a hybrid approach : use absorbers in critical areas (e.g., in the zones of the first reflections) and diffusers to maintain the spatial feeling.
It is also important to consider the characteristics of the speakers. If the Hi-Fi speakers emphasize high frequencies, more absorbers will be needed to control this area. If the sound seems too dry, diffusers will help create a more natural spatial effect.
AUTOGARSAS.LT specialists can help you select the right combination of absorbers and diffusers, taking into account your Hi-Fi system and room acoustics , to ensure optimal sound and a sense of space.

How to install diffusers and absorbers
Properly installed diffusers and absorbers can significantly improve the sound quality of a Hi-Fi system. The key is to know how and where to install them to make the sound in the room as smooth and pleasant as possible. It all starts with analyzing the room and applying the right solutions based on its size and acoustic properties.
First steps before installation
Before installing acoustic elements, it is necessary to measure the room and determine the places where sound is reflected the most. A simple but very effective method is the mirror test. It allows you to accurately identify the reflection points where absorbers should be installed to reduce unwanted reflections.
Diffuser placement
The diffusers should be mounted at a height that matches your listening position. This will help ensure even sound distribution throughout the room. It is recommended to place them symmetrically to avoid direct reflections and create a harmonious sound image. It is especially effective if the diffusers are combined with other acoustic solutions.
Positioning of absorbers
The installation of absorbers begins with the identification of the main reflection points. They are usually installed in places where sound is most often reflected - on the side walls and, if necessary, on the ceiling. If you want to control low frequencies, it is recommended to install special bass traps in the corners. It is important to leave a gap between the absorbers and the walls - this allows them to work more effectively.
Diffusion and absorption balance
To achieve a natural and balanced sound, it is necessary to combine diffusers and absorbers. Using too many of one type of element can lose the desired acoustic balance. Properly matched solutions help maintain a lively sound and reduce unnecessary reflections, preserving the acoustic "liveliness" of the room.
Technical aspects of installation
When installing acoustic elements, it is necessary to take into account the materials of the walls and ceilings of the room. Light surfaces will require different fixing solutions than hard surfaces. It is recommended to fix heavier elements in several places to ensure their stability and precise horizontal placement. Use appropriate fixings and leveling tools to ensure precision.
