2hours test made with continuous pink noise signal(6 dB crest factor) within the speicifled range, Power calculated on rated minimum impedance, Loudspeaker mounted In 35 liters(1.25ft3) bass-refiex box, tuned at 65Hz.
Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
Applied RMS Voltage is set to 2.83V for 8 ohms Nominal impedance, average SPL from 200 to 4000 Hz.
Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
