DIAMOND®

DIFFUSION PANEL

DESCRIPTION TECHNICAL DRAWINGS Image of 60x60cm model Ref.:DIA060.

The DIAMOND® is a 3D-controlled dispersion multidirectional reflection panel with a depth 60
factor that is logarithmically varied. It is, therefore, a three-dimension omnidirectional reflection 8.5
panel that controls primary reflections and fragments the energy in 64 vertices of incidence by
using the theoretical numerical sequence ratio of the primitive root as a basis for calculation.
It is built with ABS recyclable material, and its modular design makes it a particular and high-
performance diffuser. The reflection angles were optimised according to mid-size room
applications.
The DIAMOND® is an acoustic diffusion element with a lozenge geometry. The front view refers
to 64 interconnected polygons with four multiple sound diffusion angles, which determines a
diamond shape.It was created in 16 singular modules that have a quadrangular base and
different extrusion heights on each corner. The combination of those positions results in a
geometrically scattering diffusion pattern with a very attractive shape.
Thus, the DIAMOND® produces exceptional results of sound diffusion effect and provides
spaces with considerable sound perception.

IMPORTANT NOTICES

12 • JOCAVI® accepts no responsibility for any printing errors. Specifications can be modified without prior notice, if technical or commercial reasons so require.
• RAL© is an international independent colour standard system partner for industry, trade, architecture and design. Should be consulted before placing any order.

• The colours shown on this catalogue are only a reference and an illustration of the products finishing. The colours shown are not binding because brightness, contrast and colour balance may vary due to the printing process.

• Colours may vary due to raw-material suppliers' changes and some differences may occur in tonal range.
• Typical Indoor Comfort Standards state a temperature range of 20ºC - 27ºC (68ºF - 81ºF), and a relative humidity of less than 60%. These would be considered as normal operational levels of JOCAVI® products' range.

• Sizes may vary slightly due to their production method and some inherent raw-materials characteristics.
