What Frequency Range Should I Diffuse ?

Hi, I have made several spectral measurements in my mixing room and I have noticed the same problem. I Have a dip from 600hz to 2khz ranging from -1db to -4db. Should I make my diffusers in that range so I can reinforce those attenuated frequency’s by diffusing them? Let’s say i’m going to make a QRD diffuser that diffuses 700hz and cuts off at 2000hz. does it seem right ?

thank you for your videos !

Diffusion will not assist you with peaks and troughs in frequency response. It will actually make them worse. You must use broadband absorption to treat the issues.
