Next step? Problems at 45hz

Wondering if I need to keep going with acoustic treatment. Room is 13ftx13ftx13ft, with the last wall (left side) being an odd one. I currently have 4in bass traps in both corners in front of the listening position, a 2x4ft panel on each side of the listening position, and a cloud over the listening position. Rugs on all of the floors. I do have a window in front of the listening position and on the wall to the right. I plan on treating the windows asap. The biggest problem from what I can tell from the graphs is ~45hz and ~90hz. I have some odd dips at 105hz, 130hz, and 160hz as well.

Any advice is greatly appreciated! I think I got the scales right for the graphs, but let me know if I screwed it up.

That really looks like a lot of modes around 45 Hz. Probably the 1-0-0 and the 0-1-0 mode at the same time. You'll need a lot of treatment to attack that. You could also try tuned absorbers on side, rear and front walls. Keep in mind you'll need a lot of those as well.

For such a unsuitable room size (identical lenght, width, height) the measurement is not that bad.
You need thicker treatment or other pressure based absorbers in the corners at first.
