Measurement tolerance



How and where did you measure these? Was it done in half-space outdoors, maybe on the ground pointed up? What measuring system did you use? I ask all these things, because there are a lot of places for ambiguity to creep in. If measured indoors, you can expect 6dB difference in average output just from moving speakers around in the room. I suggest a fairly good amount of tolerance should be considered if consistent references and calibrations aren't in place.
