Yeah, I don't pay much attention to folk's measurements unless all the particulars are listed since they're like statistics, you can prove whatever you want with them. For HIFI/HT apps, what matters is in-room with the mic at the [various] LP[s], then averaged out. For LF outdoor apps, far enough away ground plane for the lowest frequency to unfold and math correct to 1 m /whatever. For the rest, ideally in 4pi space [up a high pole], otherwise however high off the ground the mains are likely to be.
