In addition to its effectiveness at addressing sound absorption problems, acoustic treatment is often used to open up a room by introducing a sense of air and space. Primacoustic’s Radiator Open Grid Diffuser handles this with style and efficiency.

Sporting a natural laminated wood finish and featuring a stylish grid design that enhances any room’s decor, you can mount the Radiator on your wall or use it as a ceiling cloud to help eliminate standing waves and powerful reflections in your room.

When mounted on a wall, the Radiator’s 64 cubicles break up sound energy when it hits the hard wood and scatters around the room, reflecting back in multiple directions. When used as a cloud or mounted in the ceiling, the Radiator enhances your room’s sound by creating natural trailing reverb without amplifying the compressed sound of a small space.
