Featuring consistent-radius cylindrical design, Curve Diffusor V2 offers time-coherent diffusion from low-mid to very high frequencies and built-in low-frequency absorber. Bass absorption comes from MLV limp-mass membrane on back of unit, coupled with proprietary internal impedance system. This results in room-mode-controlling Acoustic Bass Management™ down to 45 Hz. Curve Diffusor may be placed vertically and horizontally on wall, ceiling-mounted, corner-mounted, or free-standing.
