FWIW I have > 30 years of experience in the signals field. I have used some of the most expensive analog and digital measuring gear ever manufactured. I have used and have REW on my laptop along with other professional measuring software.
But since you obviously didn't read the references I pointed to to try and help you out I thought I would offer the following quote from Dr. Floyd Toole:
A simple implementation of these principles exists in the Infinity Room Adaptive Bass Optimization System (R.A.B.O.S.TM), in which powered woofers and subwoofers are equipped with a single band of parametric equalization. Supplied with the loudspeakers is a CD of test signals, a sound level meter, and a clever device for identifying the Q, or bandwidth, of a problem resonance. Straightforward instructions, or automated website calculations, lead the customer or installer through a sequence of operations aimed at identifying and attenuating the single most objectionable room resonance. In practice, most rooms exhibit only a single powerful resonance, so a single filter can be a great improvement. The system is designed to attenuate only, so the uninitiated cannot try to fill acoustical cancellation holes
in the frequency response.
You can find this in his excellent essay: Audio Science
