A real wood 2D diffuser at 1/2 the cost of the similar RPG HemiFussor. 2D diffusion is typically used on the front wall between the speakers and towards the rear of the room to improve clarity, spaciousness and envelopment. These products are acoustically quite benign and can be placed close to the listener, unlike deep QRDs. They can also be mounted on top of other acoustical panels and bass traps.
