1
2 hours test made with continuous pink noise signal (6 dB crest factor) within the
specified range. Power calculated on rated minimum impedance. Loudspeaker in
free air.
2
Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
3
Applied RMS Voltage is set to 2.83V for 8 ohms Nominal Impedance. Average
SPL from 200 to 2000Hz.
4
Thiele-Small parameters are measured after a high level 20 Hz sine wave precon-
ditioning test.
