Anthony, good point (as always from you). First, my initial thought is to avoid any absorption not to deaden the room more than it is dead now. Hence hardwood diffusers. Right or wrong, the experiments will tell. Second, I did a bit of research and found this rule in the diffusers' bible Acoustic Absorbers and Diffusers Theory, design and application, page 37:
"Precedence has shown that it is best if the listener is at least three
wavelengths away from diffusers."
The panels' I've ordered are 550Hz and up which gives minimum of 2.1m. I can do that (diffuser-to-listening-position) even in my small space.
Interestingly, on p.38 the authors even suggest that being as close as 1m away from a reflecting surface, it is better the surface is diffusive rather than plane.
