EFFECTFUSER®

DIFFUSION PANEL

DESCRIPTION Image of 60x60cm model Ref.:EFX060 (on the left) and 180x120cm Ref.:EFXCOMBI (ambient image).

Diffusion shells are acoustic treatment elements used in large volume rooms, such as TECHNICAL DRAWINGS
theatres and auditoriums, where orchestral concerts or mere recitals take place.
The installation of these acoustic diffusion components aims to project the natural sound 180
from the instruments and maintain some liveliness in the room's acoustics. JOCAVI®’s 60
EFFECTFUSER® has been designed at the scale of these needs. It is a large-sized diffuser
that provides a very homogeneous diffusion within the diffuse sound spectrum. Due to its 120 40 60 30
shape and depth, the EFFECTFUSER® has a high diffusion coefficient on medium/low
frequencies, thus making it more balanced when compared with other diffusers. This MODELS AND SIZES WIDTH
piece can be coupled and multiplied in order to suit each room's project. 120 cm
When mounted, several modules must be grouped in order to obtain a diffusion area that MODELS HEIGHT 60 cm DEPTH WEIGHT
is proportional to each space. They are properly positioned on ceilings or walls in order to 40 cm 55.5 Kg
EFFECTFUSER® | DIFFUSION PANEL obtain sound diffusion at the intended angles. EFXcombi 180 cm 30 cm 5.4 Kg
EFFECTFUSER® may also be used, like any other JOCAVI® diffusion model, in EFX060 60 cm
combination with other models of absorption panels.

IMPORTANT NOTICES

16 • 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.
