Vandersteen Audio 2Ce loudspeaker Sidebar 3: Measurements 3
The waterfall plot in fig.8 is very good, with a few mild resonances evident but also a notably clean and rapid decay in the bass region compared with many of the loudspeakers we have tested. Fig.9 shows the effect of the midrange and treble contour controls, the overall response again normalized to flat so we may show only the contour effects. The responses are a little erratic—again note that these are the maximum positions of the controls—and the action of the high-frequency contour is closer to a shelving response which engages fairly abruptly at about 7kHz. Some "crossing over" of the effects of the controls are evident between their maximum boost and maximum cut positions, but there is little overlap in the operating regions of the midrange and high-frequency controls. The maximum effect of the controls is greater than implied by their +3, -2dB markings—closer to ±6dB.
Altogether, the Vandersteen 2Ce's measurements would be more than acceptable in a much more expensive loudspeaker. That they belong to a modestly priced one indicates what is possible with refinement and competent design work.—Thomas J. Norton
