Custom Design Acoustic plates und modules manufactured in Berlin

The unique combination of diffusion and bass absorption in the 3D Diffuser 50 provide an advanced solution for optimizing the acoustics of small and medium sized rooms. Diffusion ensures that the room's sound is open and vibrant, while allowing you to control the sound with high precision. Bass absorption is essential for controlling resonances in the room and make low end defined and punchy.

The 3D Diffuser 80 features different a geometry and pattern to its sibling. A sharper angle element and internal cavity volume provide slightly different diffusion and absorption characteristics. Like the 3D Diffuser 50, it is successful in optimising acoustics in small and medium-sized rooms. Small rooms in particular exhibit resonances (room modes) in frequency regions at which the 3D Diffuser 80 is most effective. It is mainly used as a ceiling panel, but can also be installed on walls.

The Diffractal 21-GL is the largest diffuser we produce and is effective from 250Hz to 20kHz. It is a quadratic residual diffuser [QRD] featuring sub-structures which are also high-frequency QRDs. This system provides the widest frequency range of true diffusion of any known diffuser and it increases the perceived size of a room, psychoacoustically.

The Diffractal 7 is a modular version of the Diffractal 21-GL that allows interconnectivity of up to seven individual Diffractal 7 units. It provides great flexibility in acoustic design and installation, and being smaller and lighter than its sibling, it can be mounted onto ceilings or sidewalls as well as the rear wall. The Diffractal 7 modules can also be partnered with geometrically different Diffractal 7 modules (e.g. different depths, inverted versions) and combined in a modulated sequence system to provide a more uniform and extended low end diffusion.

Broad band absorbers are the most effective in reducing reverberation time and always desirable as first-aid solution in most of the rooms.

While highly effective they cannot completely eliminate undesired frequency resonances when used in isolation; this applies to any room less than 100 square meters in area where additional acoustic elements are not used. Broad band absorbers can be easily wall mounted or suspended from the ceiling thanks to their rigid framed construction.

This type of absorber is called a bass trap because it only works as an absorber in a defined, narrow, low frequency range of 30 to 150 Hz. The device must be optimally tuned for each room and placed correctly in it. We manufacture bass traps individually for each project, and only after a detailed simulation of low-frequency resonances or based on the results of acoustic tests.

Acoustic treatment room kits offer a selection of acoustic elements from within our range including various diffusion and absorption options. Our acoustic kits are pre-calculated sets for rooms varying from 16 to 40 square meters in area. The number of panels in each set can vary from 8 to 50 pieces and come in a variety of colour options.
