Speaker measurements differences


I noticed that one the same speakers’ measurements differ depending who does the measurements.
Here is an example, first link is Stereophile review of Sophia, note the significant peak in 50-60Hz range followed by another one at 200Hz.
Second one is from SoundStage, no trace of this peak.
MF and HF range look almost identical, same spacing of peaks and dips.

To amplify what Newbee says: Get a sound pressure meter and a test recording and make a few static measurements with white and pink noise from several locations in your room. Do not be alarmed when your results show big, and I mean BIG, swings in response below 500 HZ.If you speakers were top drawer these results would not change much. A more sophisticated test unit, can make dynamic test measurements and do the math necessary to evaluate them. Multiple 10-20 db swings in room are usual.
Either trust you ears, or trust the people who can do math, but do not make buying decisions on stuff you cannot understand without some considerable technical background.
