WOODFOIL® AcSh® The Woodfoil® is a slightly concave diffusion panel, made of varnished birch plywood on a soft wood structure. This diffuser is great to be used in concert halls, such as theatres and auditoriums, and is ideal for building acoustic diffusion shells. This model has two options: the Woodfoil® diffusion panel, which is made of plain birch plywood, and the Woodfoil® Ab, which has different holes that provide it with a higher absorption coefficient. Its format allows us to make the appropriate adjustment, by using several panels and positions through 90º rotations, in order to obtain the goals required for each room. Both the angle and the gyrate of this piece were calculated to provide a more versatile use. When using multiple pieces jointly, the angle of incidence never is too convergent, thus providing a homogeneous scattering diffusion of sound energy, which contrasts with other models from our brand that have a different development conception. The Woodfoil® is available in various wood finishings or regular colours, as an option, thus allowing an appropriate background for each space. The mounting process is rather easy by simply using the docking accessories that are supplied.
FEATURES Manufactured in birch plywood.
Two options: Woodfoil® (diffusor) Woodfoil® Ab (diffusion with absorption characteristics)
NRC: 0.23/m2 (WFL060); 0.62/m2 (WFL060 Ab)
Average diffusion Woodfoil®: 0.68/m2 [>100Hz;<5KHz].
Average diffusion Woodfoil® Ab: 0.51/m2 [>100Hz;<5KHz].
Installation: mounting accessories included Depending on the space available on the stage, more or less elements may be used in order
to form the shape of a perfect shell.
Built on a modular configuration with 120 x 120cm pieces, up to four modules can be
coupled in height, thus totalling a diffusing homogeneous surface of 480 x 120cm.

Based on works and experiments in the field of sound wave diffusion and the positive
aspects that result from the presence of diffusers in rooms, we have built this acoustic
Therefore, we are presenting new design proposals that are less common in diffusion
structures designed for mobile use.
The WOODFOIL® AcSh® are an easy-to-install
portable acoustic diffusion shells meant to be used in certain types of musical concerts.
It is a piece that changes the room's acoustics by enhancing its features.
Diffusion shells are acoustic treatment elements used in large volume rooms, such as
theatres and auditoriums. They may also be used outdoors for the performance of concerts
by large orchestras or just recitals.
The installation of these acoustic diffusion components is meant to project the
non-amplified original sound from the stage towards the audience.
This will enable to hear the sound that comes directly from the sound sources and
instruments, without the characterization or colouring inherent to the use of
electro-acoustics. These shells also enable the stage and the room to be within the same
space and not separate in two by the mouth of the stage. These pieces do not need any preparation prior to their installation, just a free stage with good access.
They must be coupled and multiplied in such a way that is adequate to each project in
order to obtain a diffusing area that is proportionate to the space in question.
