July 2004 Ascendo System Z-f3 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 low distortion levels under those conditions, we have added a second measurement performed at 95dB to give an indication of performance under higher-output conditions. ADDITIONAL NOTE: This speaker has two switches that alter the output of the tweeter and the woofer. All standard measurements were done with the switches in the manufacturer-recommended position: tweeter set to "H" and woofer set to "N." An additional frequency measurement was performed and is shown below with the tweeter set to "N" and the woofer set to "H" to show output variations. All loudspeaker measurements are performed independently at the National Research Council of Canada. Please click to learn more about how we test loudspeakers there. All measurement data, including graphical information displayed below, is the property of SoundStage!. Reproduction in any format is not permitted.
