Axiom Audio Millennia M80Ti Loudspeakers: Measurements

PLEASE 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 very 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.

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.

Frequency response, 20Hz - 20kHz (measured @ 2m, plotted @ 1m)
Loudspeaker sensitivity (averaged 300Hz - 3kHz, 2.83V/1m)

Top curve: on-axis response
Middle curve: 15 degrees off-axis response
Bottom curve: 30 degrees off-axis response
Sensitivity: 90.0dB

Frequency response, 20Hz - 20kHz (measured @ 2m, plotted @ 1m)

Top curve: 45 degrees off-axis response
Middle curve: 60 degrees off-axis response
Bottom curve: 75 degrees off-axis response

Listening Window, 20Hz - 20kHz (measured @ 2m, plotted @ 1m)

Response curve is an average of five measurements:
on-axis, 15 degrees left and right off-axis,
15 degrees up and down off-axis

THD+N @ 90dB, 50Hz - 10kHz (measured @ 2m)

Top curve: frequency response @ 90dB SPL
Bottom curve: THD+N @ 90dB (50Hz - 10kHz)

Additional Measurement
THD+N @ 95dB, 50Hz - 10kHz (measured @ 2m)

Top curve: frequency response @ 95dB SPL
Bottom curve: THD+N @ 95dB (50Hz - 10kHz)
