From many years the Quadratic diffusers became a classic shape in architectural acoustics. Jocavi revisited and made a new design of the oldest ever project of acoustic diffuser modules.

Starting from the same principle of the calculations for Quadratic diffusers, we reviewed it with a new approach and add a new energy flow calculation theory that adds better scattering predicates and advantages. NEO 3Q® has a three grade design pattern, making the distribution of energy homogeneous and balanced within its effective frequency range.

The phase grating surface of the NEO 3Q® is designed to provide a more uniform diffusion of the sound reflections radiated against it, mostly in the mid and high frequencies sound field.

In the cases where the reflections are disturbing the sound image and it is not advisory to add further absorption, diffusers are a very useful solution to reduce flutter echoes, early reflections, comb filtering etc., these components must be placed on the disturbing surface so that these derogatory characteristics can be manipulated.

This model is made of ABS, with a composite filling of recycled materials, which gives itthis product a specific mass and also contributes to its consistence. The ABS as an external raw material makes it the fastest and most specific properties required for a diffuser like this, along with UV protection, impact resistance, durability and fire resistance Bs1.

NEO 3Q® can be installed in recording studios, music education facilities, auditoriums and performing halls. It is available in several different colours By using our fastening materials it can be applied on walls and ceilings, as well as "T" type mounting bars for fake ceilings.

To adjust the diffusing properties of these models to the room where this product is applied, the placement of the pieces must be taken into account in order to obtain its best performance, for technical support contat us at:

NEO 3Q® AcSh®P - N3Q120P

The diffusing acoustic shells are acoustic treatment elements intended for large volume rooms, such as theatres or auditoriums with a stage where orchestral concerts or mere recitals take place. These acoustic diffusing components are meant to project the non-amplified original sound from the stage to the audience. This will enable people to hear the sound coming directly from its sound sources and instruments, without the electro-acoustic inherent characterization or colouring. This panel also aims to enable the stage and the room to be within the same space and not separate in two by the mouth of the stage. JOCAVI®'s EFFECTFUSER®, WOODFOIL®, PLURA® and DYNAMICFLOW® models have been designed at the specific scale of these needs. Due to its shape and depth, they also have a high diffusion coefficient on medium/low frequencies. The all are large-sized diffusers that provide a very homogeneous diffusion within the diffuse and sound spectrum. Manufactured in ABS (except WOODFOIL® in wood) with a rigid framework, these pieces can be coupled and multiplied in order to suit each project's demands. When mounted, several modules should be grouped so as to obtain an area that is proportional to each space. Mounting: They can be hung from the ceiling in a strategic position in order to obtain sound diffusion in the required angles. They can also be mounted with a motorized rigging system from the stage ceiling. These elements / modules are fastened with steel cables by using appropriate mounting accessories. Their low weight makes mounting easier. As with any other JOCAVI® diffusion panel, these models can also be applied on false ceilings, flat ceilings or walls. The combination of the various EFFECTFUSER®COMBI and the other models Plates, diffusing pieces must be optimised so as to obtain a diffusion as uniform as possible in the entire room.
