I am sitting 4meters from the speakers - and I could put the speakers further back in the corners
The whole room is designed as an interaction between the Varitunes bass traps, the wings, the TP600 pillars and the additional custom made traps (ceiling, front corners, behind backwall). They act as a single unit and are tuned at the location by Matts Odemalm from SMT. The distance from back wall is not an issue, it was integral part of design.
If the Wings would be normal diffusers, you would be right: with all other diffusers I know, you typically need to sit at 3 times the wavelength (typically 3meters for 340Hz) to avoid ghost speakers effect and to get the sound field together.
The wings are not normal diffusers, they are developed to optimize in the time domain. They are designed as a single broadband time delay line module, which works very well in the near field instead (40-60cm distance required as minimum). The key design criteria is not how broadbanded they diffuse, but rather how broadbanded they delay the sound inside the delay line compartment.
See attached a CATT simulation of the flower wings:

hope it helps, Matts from SMT can give you more info.
