To expand on what has already been said "unless you're listening in an anechoic chamber, aneechoic measurements are useless" is spot on. No audiophile has an anechoic chamber.
How a speaker controls itself independently of the room is a much more valid measurement- this can be observed by polar patterns and how the dispersion is controlled across the frequency range.
