It can cure nulls but at the cost of throwing away power. You set the worst null as a base and then consider everything above a peak. But if there's a deep null you will be throwing away tons of power effectively.

That was my point. It can be done but it's a lousy solution.
On the other hand, I get great results upstairs with the stats for several reasons: the room dimensions are favorable, I use a small forest of bass traps and am free to optimally position the speakers. I spent hours measuring the results of various trap, speaker and listening position positions.
While this is only a third octave plot, the results do indeed sound quite neutral.
impressive. curious what stats? did you use any equalization or just placement and treatment in order to have no room resonances showing?
It is an EQ-free environment simply based upon (lots of) optimization.
I do, however, use two narrow bands of the parametric EQ built into the Emotiva processor in the HT for attenuating a couple of peaks.
Even so, I cannot fix the 40 hz (and to a lesser degree 80 hz) suckouts. Room dimensions are not ideal (20x17) and I don't have the same latitude for placement. Even the following took some doing by experimenting with numerous combinations of high and low pass filter frequencies and sub output. Earthquake simulation is down somewhat, but most of the upper bass is reasonably flat.
