THE PRODUCTION OF THE DIFFUSERS IS SUSPENDED UNTIL AUGUST 15TH DUE TO ANNUAL LEAVE.
In the meantime, you can still place orders, but you will not receive your order until after August 15th.
Pair of acoustic diffusers consisting of one type A diffuser and its inverse type B. These two types are mutually mirrored with respect to each other, in order to avoid problematic phase correlations that occur when two identical elements are placed in proximity.
Each diffuser is composed of 20 pre-cut lines, to be assembled by placing them next to each other.
Three years of research were necessary to develop this revolutionary diffuser in terms of its efficiency and price. Nothing was left to chance in its design. Comprised of 400 "pseudo cells" on a stick in just 60cm², this French-designed and manufactured diffuser offers remarkable diffusion and dispersion properties, making it an essential reference.
Inspired by the QRD (quadratic residues) model, the PRD (primitive root) model, and the improved models LSD (Lüke sequence) and PWRD (power residue), the MDD (Mac Door Diffuser) sequence brings together the best of the most renowned sequences based on prime numbers to merge into a new formula patented in 2019, designed and optimized for stick diffuser designs.
This revolutionary sequence has the following characteristics:

3 years of research, over 6,000 hours of study, experimentation, questioning of what has already been done in terms of diffusion, and the creation of about sixty diffuser devices made with different materials and sequences in order to understand, find, and achieve the best acoustic diffusers, have led me to develop my own method for simulating the behavior of a diffuser, a demonstration method based on observing a 'ripple tank,' a serious questioning of the certainties we had about their behaviors, and finally, my own distribution method, which varies depending on whether the diffuser design is based on rods or wells.
When it comes to diffusers, "experts" generally agree on a preference for well-based designs over stick-based ones. However, my investigations have led me to the conclusion that, depending on the sequence type and implementation constraints, stick-based designs often yield better results when the number of cells is substantial. After selecting the diffusers (generated randomly using the "Mersenne Twister") that exhibit superior characteristics to QRD, PRD, LSD, and PWRD models, in line with the predictions of my analyzer using the "brute force" method, I set out to examine the similarities in their designs to identify the elements necessary for optimal diffusion.
