December 2007 JansZen Model One Loudspeakers: MeasurementsPLEASE NOTE: Our standard is to provide the THD+N measurement at 90dB with a measuring distance of 2 meters (within the anechoic chamber). Since this speaker produced some distortion anomalies at this level, we have added a second measurement performed at 85dB to give an indication of performance under lower-output conditions, as well as a corresponding Deviation from Linearity measurement at the same level. Furthermore, since this is an active speaker, meaning that it has has built-in amplification and is driven by a line-level signal, measurements such as sensitivity, impedance and elctrical phase are not applicable. All loudspeaker measurements are performed independently at the National Research Council of Canada. Please click to learn more about how we test loudspeakers there.
