The Primacoustic Radiator Open Grid Diffuser fits into standard ceilings. It is ideally suited to act as a portal between the room and the plenum to increase the sense of space by allowing acoustic energy to transition naturally between the two air spaces. This approach has been used for years by studio designers to enhance the sound of a room and create natural trailing reverb without the compressed sound of a small space.
The Radiator can also be used as a cloud: A series of carefully positioned mounting holes allow multiple Radiators to be ganged together with the supplied hardware to create ceiling arrays that can be suspended over the recording work space. This will help eliminate standing waves and powerful reflections. Finally, when combined with Broadway panels, a host of creative designs can be introduced to control the acoustic environment while introducing a sense of design and flair to the room.
A natural laminated wood finish and great looking dove-tail joints make the Radiator the perfect centerpiece to add spice to any room décor.
Breaking up sound energy with the Radiator
The Radiator is not a diffuser in the true sense of the word. True quadratic residue diffusers (QRDs) employ a series of mathematically calculated wells based on prime numbers that will break up sound energy in such a way to ensure that all frequencies are equally distributed over time and space to provide both spatial and temporal diffusion.
When used as a ‘diffuser’, the Radiator’s 64 cubicles break up sound energy as it hits the hard wood boundaries and scatters it around the room as it reflects back in multiple directions. This gives smaller rooms a sense of space and air.
The Primacoustic Radiator is a 24″ x 24″ x 3″ open grid acoustic diffuser that is used in a variety of ways to reflect high frequency sound energy in a random fashion, creating a sense of air and space in any room. The Radiator can be used as a standard flush-mount wall diffuser or mounted over top of Broadway panels to improve performance and add lower frequency absorption.
They can also be used as a suspended cloud or dropped into a T-Bar ceiling grid to take advantage of open ceiling spaces and plenum to create a balanced, large room sound without direct reflections and echo. All hardware is included to hang the Radiator on the wall, or to link multible units together.
The beautiful natural birch finish and limitless number of uses makes the Radiator the perfect addition to any room décor, from studios to waiting rooms.
