A Modern Classic of QRD Diffusion
Inspired by QRD sequences used in studios for decades, this 2D panel condenses the efficiency of diffusion on two axes into a compact format. Its regular internal spacing and carefully studied depth promote even dispersion, perfect for treating the back of a control room, balancing a Hi-Fi listening area, or refining a recording booth without drying it out.
Who Is It For and Which Rooms?
This diffuser is designed for home studios, professional studios, control rooms, and discerning audiophiles. Placed at early lateral reflection points, on the rear wall, or on the ceiling, it improves clarity, stereo imaging, and perceived depth. Complementing absorbers, it helps achieve controlled reverberation time while maintaining mix liveliness.
Design and Performance Serving the Listening Experience
The two-dimensional QRD structure distributes incident energy in both horizontal and vertical planes. The result: fewer flutter echoes, a wider soundstage, and an expanded sweet spot, especially in the sensitive midrange and upper midrange registers.
The untreated birch plywood ensures rigidity, stability, and a natural finish that is easy to oil or varnish. Thanks to its light weight and rear hanging option, setup is quick. Need mobility? Combine it with HOFA removable frames for adaptable acoustic configurations.
