You really only have one issue, and it's that 22hz null that is pretty obvious. The rest are modes and are fine and can be EQ'd to be flat. Nulls cannot be fixed with EQ or anything. That's dependent on placement in room relative to listening position(s). Since you have TWO subs running, the goal is to move them until that null goes away. You should be able to move the subs around a little and watch that null move. As long as one sub is covering up the null from another sub, the perceived response will be flat at the listening position. So move your subs a little and re-measure until that null is gone.
There aren't any nulls in that graph!
See my graphs for what a null looks like (first graph green line has a null at 50Hz), and all 4 subs have a null around 115Hz. Post EQ graph shows what can and cannot be fixed with EQ alone. These aren't smoothed at all either. The only thing I did wrong was label the initial graph after working 14hrs, then re-arranging the room, and doing sweeps when I was tired and couldn't tell colors apart anymore.
