I have speakrs with great directivity and don't have any reflection from sidewalls and frontwall. I tested QRD diffusion between the speakers with a 2m*1,5m area and there was no audible difference and almost no difference in the ImpulseResponse (reflections.) As I have heavy absorption on the backwall I wouldn't have expected combfilters between front and backwall anyway. Without any backwall absorptions or diffusion, diffision on the frontwall will help with combfilters.
Combfilters in general are responsible for almost all waviness in your frequency plot.

Exactly! For the higher degree reflections furniture is best to manage the reverb in a room. Depending on the speakers, furniture can even be enough for first order reflections. However when it comes to the ceiling you do need some treatment... floor not so much as our brain is used to that reflection.Most of these simple two-way designs sound best in a room with comfortable furniture. Before concentrating on wall treatments, get a nice couch.
