GIK Acoustics introduce Q11D diffusors

Published 9/1/26

Two new quadratic diffusor designs announced

GIK Acoustics have just introduced two new additions to their growing line of diffusors. The Q11D is based on the design of the existing Q7D, but employs an 11-root well sequence that shifts its effective bandwidth higher into the midrange.

The new diffuser is slightly wider than the Q7D and features narrower wells, allowing the two models to be used together in modular arrays for broader coverage. It’s manufactured from CNC-cut wood laminates, and is available in four different colour finishes. Two sizes are available: Standard and Demi, with the latter sporting a half-height design aimed at installations with lower ceilings or for use in interleaved two-dimensional scattering designs.

Recommended Placement

Rear wall diffusion in mix, mastering or listening rooms.
Behind dipole or open-baffle speakers.
Across the front wall or rear side walls of two-channel or surround systems.
In live rooms for percussion and acoustic instrument tracking.

“Quadratic diffusors are the gold standard when it comes to predictable, consistent 1D diffusion. These are the right device when you need to maintain as much mid and high frequency decay in a space, while still providing control over reflections and flutter. The Q11D is a higher frequency diffusor than a Q7D, with more complexity due to the higher number of wells. It has scattering effects down to 570Hz, with even diffusion up to 3900Hz. This type of quadratic diffusion excels in large spaces, live rooms and auditoria where a smooth, even midrange decay time is desired.” - Mike Major, Acoustic Designer, GIK Acoustics
