First, to answer your question Friend, it measured very well. Extremely well.
I don't normally even read the measurements section as to loudspeakers so I had to go back and read it to answer your question. What most impresses ME is that the rated sensitivity, low-end frequency response and impedance were spot-on as was mirror imaging (driver matching) between the loudspeakers. Cabinet resonance was very well controlled which means nothing to me. The measured FR was ever so slightly tipped up but JA did not find then to be bright in his [weird] room. For some reason JA did not seem to measure dispersion characteristics or even discuss them to any degree in his listening impressions. Overall, assuming that they were not cherry-picked samples this indicates very fine QC and his listening impressions certainly indicated very high value-they played loud without break-up or strain. I say this without a scintilla of personal buying interest. Would never happen.
