1- For different impedances, please ask.
2- 2 hours test made with
continuous pink noise signal (6 dB crest factor). Power calculated on rated
minimum impedance.
3- Power on Continuous Program is defined as 3 dB greater
than the Nominal rating.
4- Applied RMS Voltage is set to 2.83V for 8 ohms or
2.0V for 4 ohms Nominal Impedance
