While the CTA-2034-A spins are great for loudspeaker designers and geeks (like me), for the consumer to judge how a speaker will sound in the room it is all about the estimated or predicted in-room response. From the standard:
"Unlike previously published standards, this standard describes how to measure and report the directivity of a loudspeaker, whether it stands by itself or is mounted in or on a wall or ceiling. It also describes how to use this directivity data to estimate the in-room frequency response that more recent research has shown correlates well to subjective listening preferences of consumers."
That "subjective listening preferences of consumers" is directly related to Sean Olive's and earlier, Floyd Toole's scientific research that if you dig through them, there is a clear and repeatable preference of what listeners like for an in-room frequency response.
From CTA-2034-A, comparing the estimated in-room response to an actual measured in-room response, it is quite accurate:

When it to comes to room correction, and for those that have not read it, JJ's presentation on
Acoustic and Psychoacoustic Issues in Room Correction is a good read. The first 31 slides in his
Power Point presentation does a great job of explain why we hear what we hear in small room acoustics and how it relates to room correction.
Sorry for the OT
@QMuse Kali eq results look very good!
