1For different impedances, please ask.
22 hours test made with continuous pink noise signal (6 dB crest factor). Power calculated on rated minimum impedance.
3Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
4Applied RMS Voltage is set to 2.83V for 8 ohms or 2.0V for 4 ohms Nominal Impedance
