Diffraction Around Diffusors

Hello,

I have a big bass trap (200x113x25cm) built on a wall cavity(58cm) on the backwall of my studio, I would like to build a big diffusor in front of it in order to diffuse some sound but still being able to absorb low frequencies.
Is it going to work? How can I calculate which frequency is going to diffract around the diffuser (so i can tune, maybe the low frequency of the diffuser to that frequency) ?
I attached an image to explain.

The dimension of the diffusor that matches the wavelength is the cutoff for diffraction.

To clarify, by looking at the OP drawing, The height of the diffusor looks to be the smallest dimension. Use that dimension to calculate the cutoff.
