True QRDs are tricky to build because they are have different, varying depths of relief, depending on what frequency range you are trying to diffuse all determine by quadratic equations. I am no math guru. [Fourth most frequent lie: architects are good at math.] That makes manufacturing costly and DIY difficult. Bass diffusers can get quite large and deep. For them to look good, you need nice wood and great woodworking skills. Of course, you can cover them with acoustically transparent fabric (speaker cloth or surf fabric) with an ever so slight loss of the highest frequencies. I really cannot steer you towards a reasonable product or DIY approach, but I googled it and got lots of hits, so you can try that.
Once again, it really depends on what you want to achieve. Diffusion is good for increasing reverb time or canceling echos without loss of energy. I am not sure why one would want to increase reverb time in amplified audio playback. That should be accurate in a good recording and accurately reproduced with good equipment. Absorption can eliminate echos to and lessen diffusion, and thus, increase clarity. This comes with with a decrease in overall sound pressure, but one can always turn up the volume. The key in any of this is balance across the entire audible frequency range so that your not creating arbitrary and unintended tone controls, unless damping brightness or excessive bass energy is your actual goal.
For me, at home, I don't worry about room treatments. I just play music I like and enjoy it while spacing on the beautiful Turkish Hereke rug on the floor.
And, I am getting dumber all the time.
