From the AS review:
“We show a dip post our peak in low frequency but they don't. The reason is that they are using gated measurements to eliminate echos and that hugely reduces resolution in a few hundred hertz (to one or two data points).”
(‘They’ being Stereophile).
Why on earth would anyone be interested in the sound of his or John Atkinson’s room? I’ve only skimmed the review, but that seems a massive flaw to my eyes similar to Keith’s +/- 15-20db or whatever ‘measurements’ of various speakers which have little value beyond assessing the impact his room and setup has on the sound he hears. To my mind, unless the intent is to assess a speaker in *your* room (which is how I use them and I’d never argue my measurements of my Tannoys, 149s etc were anything other than that), measurements in anything other than an anechoic chamber is of very limited use. John Atkinson, who’s measurements I respect a lot, obviously uses gating to try and take his room out of what is intended as a more general and useful measurement.
Still interesting and to be encouraged, but I’m far more interested in the impedance/phase plots than the room measurements. Those are actually of use to me!
