(1) for different impedances, please ask.
(2) 2 hours test made w/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 nominal impedance. [single]
