For different impedances, please ask.

2 hours test made with continuous pink noise signal (6 dB crest factor).

Power calculated on rated minimum impedance.

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 or 2.0V for 4 ohms
