Many people spend thousands on their equipment and never think of the room. Your room is the most important interconnect in your system. Diffusion is the best way to “open up” the sound of a system and improve image width, depth and specificity. For sale are two pairs of 2’ x 4’ AQD diffusers. This gives you two pairs of matched diffusers. One pair can be used between the speakers to create an image without reflections or glare. The second matched pair can be used in the rear of the room or in combination with absorption for first and second reflection points on the sidewalls. The diffusers are made of dense three pound foam. It has taken years to find a consistent supplier for this higher density foam. Diffusers are unpainted and new. Pricing will increase after January 30.
