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 and 4V for 16 ohms Nominal
Impedance. Average SPL from 200 to 4000 Hz.
4 Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning
test.
