Help with room treatment

[itoa]

My room is almost square - 3x3.3m (about 10 ft) - I know I'm doomed. I did quite a lot of treatment already, but the situation is still dramatic . Can anybody help me? Should I move my stuff? Buy additional traps?

Modes:
height - 66, 132 Hz
width: 57, 115 Hz
Still huge!

I've tried to move back and forward with speakers.. No significant improvements except notch/peak movement.
