I doubt this statement, because anechoic speaker measurements (usually) only cover a subset of the inherent design parameters and specifications of a speaker concept. Minute timing differences between drivers, production tolerances, different dispersion characteristics, different resonance and absorptions characteristics of the speaker housing, diverging crossover designs may not show up (completely) in anechoic measurements, but might
influence the relevant sound characteristics in a specific room due to given speaker and listener (microphone) positioning. There is no "complete" set of parameters for a given set of speakers available, which will cover all and every aspect of a speaker design. Not to speak about the psychoacoustic elements of human hearing, which (unexpectedly) influence the individual listening experience by its own. If there where, speaker design would not be partial art but just applied craftsmanship and design rules, easily handled by an automated algorithm. Unfortunately, as we all (should) know, this is not the case, or there wouldn't be a multitude of speakers available on the market with diverging opinions about them by consumers and experts.
Thus two speaker sets A and B, measuring the same within an anechoic chamber, may still not "sound" the same in a "real" listening environment with its given (mostly uncontrollable) properties due inherent design properties, furniture, decorations, room and positioning asymmetries, clothing of people present etc.
They may even sound completely different to the better or worse in another environment, as we all (probably) have experienced already.
