1 Two hour rating using IEC60268 noise based on minimum impedance 
2 Mid-band based on nominal impedance; 2.83 V at 1 m 
3 Calculated as the nominal sensitivity plus 10× the log of continuous rated power in volts squared divided by nominal impedance 
4 Calculated as the continuous calculated max output plus 6 dB
