Vicoustic Multifuser DC4 Acoustic Diffuser Panel

Bi-dimensional EPS diffuser panel for walls and ceilings, supplied in boxes of four

This is the sound panel that's seen in so many Upscale Audio employee homes. It's light and easy to mount, and it looks really good. People actually ask if it's modern art!

The Vicoustic Multifuser DC4 is an acoustic diffuser panel designed to scatter sound in both the vertical and horizontal planes. Used on walls or ceilings, it helps reduce strong reflections while preserving energy in the room, making it a useful treatment for hi-fi rooms, home theaters, studios, and other sound-critical spaces.

The DC4 works primarily in the mid and high frequencies, where diffusion can improve clarity, speech intelligibility, and music definition without deadening the room. Its bi-dimensional surface creates multi-reflection behavior, helping the listening space sound more open, balanced, and natural.

This 4th-generation Multifuser has a refreshed design with softer edges for a cleaner, more seamless look. It is made from high-quality expanded polystyrene, keeping each panel light and easy to handle while maintaining the acoustic performance of Vicoustic’s DC diffuser series.
