We just finished build a set of 12 custom 2D diffusers for a client in the Pacific Northwest based on the awesome BBC article. When they are all laid out they look amazing and they sound great too! The diffuser frequencies from around 1Khz and above and can be special ordered for $299 a piece or 4/$1000. They are 4″ deep and 18″ x 18″ square with a grid of 144 blocks and wells.
