I laughed for about 5 minutes after seeing that photograph. does the mfg of the test equipment instruct the user to move the speakers outdoors when performing those measurements? That's not a good methodology for testing a speaker, plus I would use the cables that the MFG recommends for their speakers when connecting to other components such as amps and pre amps. The reason is the mfg uses equipment/cables in their listening rooms when designing and testing their equipment, so they might have recommendations for obtaining similar test results.
It is insulting to my intelligence that a reviewer would take home audio speakers and move them outside to perform measurement tests. Every time I've been to an outdoor concert, wind has a HUGE factor on various frequencies, so I'm sure testing home audio systems outdoors is, well, kind of stupid, IMO. Aren't you supposed to use an anechoic chamber for those kinds of measurement tests instead?
