Q11D Quadratic Residue Diffusers

The Q11D is a precision-cut, 11-root one-dimensional quadratic diffuser that adds rich spatial depth and clarity to any critical audio environment as part of a complete treatment strategy. Slightly wider than the Q7D but sharing the same height, the Q11D features narrower wells for a voicing slightly higher in the midrange, while visually complementing the Q7D for modular arrays. The Q11D is available in multiple finishes and in both standard and Demi sizes for creative layout flexibility.
