Any sharp dips can be ignored, you won't notice them. The extra sub only eliminated the sharp dip...

I like the green plot better........

Since I can't move my subs, I know room treatments are recommended before EQ. Is it a trial and error thing, or how would I go about using room tx. to make this the best possible curve before I EQ? Do I just spend some money on bass traps and try them in different corners to see how it helps? Or should I just EQ it and call it good?

Treatment doesn't help a lot in the modal region. The traps have to be too large to be practical. It's movement or EQ. But there's really not a lot wrong with your response.

Great. I will just EQ it and be done with the bass. What is the modal region? I will post some full range graphs later. Do treatments often help at higher frequencies or when do people start implementing wall treatments? Does the response have to be really bad to make a difference?

What is the modal region?

This would depend on the room, as it refers to the modal frequencies for the standing wave resonances set up between parallel surfaces in your room. There are axial modes (two surfaces), tangential modes, and oblique modes. Long story short - these cause the peaks and dips in your subwoofer response.

These types of acoustical questions are better asked in our acoustics forum section. We try and limit discussion here to REW specific questions.
