Acoustic Geometry

Medium Curve Diffusor

Made by Acoustic Geometry of Chaska, Minnesota, the Curve System diffusors use a cylindrical, constant-radius wooden-framed front to provide phase-coherent, broadband diffusion, with a built-in mass-loaded-vinyl membrane bass absorber behind the diffusing face. The company is a small specialty room-treatment maker (not a mass-market brand), sells direct and through a limited dealer network, and each panel is available in a wide range of fabric, paint, and wood-veneer finishes rather than a single fixed SKU — reviewed favorably by Stereophile's John Marks.
