Walkallen Taos Loudspeakers: Measurements

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: 85.5dB

Additional Measurement (15 degrees below-axis)
Frequency response, 20Hz - 20kHz (measured @ 2m, plotted @ 1m)

Curve: 15 degrees below-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)

Impedance curve

Vertical axis: impedance
Horizontal axis: frequency
