A few unusual filters in that set. I'm presuming they are for an FBQ2496 in the path to the sub? Do you have a measurement file for the sub without any EQ applied? What were you addressing with that 390Hz filter?

A good plot to use when tracking down places for absorption panels is the Energy-Time curve. Set the Y axis to % FS, the spikes show reflections. You can get an idea of how much further the sound travelled via a reflected path by measuring the time from the main spike to the reflected spike, multiplying by the speed of sound then gives you the additional distance. REW can handle that for you, if you place the cursor at the tip of the main spike, then hold down the Ctrl key and press and hold the right mouse button you go into measure mode, REW will show you the time difference and the equivalent distance in metres and feet. To get an idea of which surface a particular reflection is from make new measurements after moving the mic a foot or so, if you have moved closer to the surface that the spike you are looking at is reflecting from it will have moved closer to the main spike, if you have moved away it will have moved further away from the main spike. You can also place panels on likely surfaces and see which spikes they affect.

You may have some problems with reflections from the wooden frame behind the screen. The further forward you can place the speakers the less of a problem that will be.
