GRAND acoustic panels are stylish sound absorbers made of high quality natural wood and designed for effective low end absorption. These acoustic absorbers are made with use of high density acoustic wool, which delivers broadband sound absorption in A class. They can be placed behind dipole speakers to round off sharp reflections, reduce resonances and eliminate SBIR effect. Filled with the best damping core material available, GRAND Absorbers effectively reduce room modes and decrease reverberation. They can also be used to treat early reflection points as they have excellent absorption properties over a wide frequency range.

INSTALLATION
Grand Absorber by default are free-standing panels. However, they can also be hung on the walls using an appropriate mounting system. It is not recommended to mount them on the ceiling due to their high weight.
APPLICATION
Grand Absorber panels are high-performance acoustic absorbers designed for treating early reflections and reduce room reverberation. They are very effective in eliminating the SBIR (Speaker Boundary Interference Response) effect which causes nulls and peaks in the frequency response. For this reason they are highly recommended for treating the wall behind the speakers. They can also be used to control side and back wall reflections in the room.
