Acoustic sound diffusion keeps sound waves from grouping, so there are no hot spots or nulls in a room. In fact, sound diffusion greatly widens the "sweet spot" and lends a strong, 3D sense of openness to a room, making it easier to hear "into" a mix. As a companion to the Metro 2" Acoustic Absorber and Metro LENRD Bass Trap, Auralex now features the MetroFusor Sound Diffusor. Custom made for Auralex from high quality EPS (expanded polystyrene), the panel is lightweight, affordable, easy to paint, easy to mount and inexpensive to ship. The MetroFusor features the same distinctive, proprietary surface contour as the other Metro products for a clean, consistent architecturally-pleasing appearance that looks upscale and attractive in even the most visually demanding environments.
