12 hours test made with continuous pink noise signal within the range Fs-10Fs. Power calculated on rated minumum impedance. Loudspeaker in free air.

2 Power on Continuous Program is defined as 3 dB greater than the Nominal rating.

3 Applied RMS Voltage is set to 2.83 V for 8 ohms Nominal Impedance.

4 Thiele-Small parameters are measured after a high level 20 Hz sine wave preconditioning test.
