Power handling specifications refer to normal speech and/or music program material, reproduced by an amplifier producing no more than 5% distortion.
Power is calculated as true RMS voltage squared divided by the nominal impedance of the loudspeaker.

AES Standard (60Hz – 600Hz).
– Thiele-Small parameters are measured after a two-hour power test using half AES power. A variation of ±17% is allowed.
