Description
NOTES:
1、Two hours test according to AES 2-1984 Rev. 2003. Power calculated on rated minimum impedance.
2、Maximum power is defined as 3dB greater than Nominal power.
3、Applied RMS Voltage is set to 2.83 V for 8 ohms Nominal Impedance.
4、Xmax= [(winding depth – magnetic gap depth)/2] + (magnetic gap depth/3).
5、Thiele-Small parameters are measured after a preconditioning test.
6、Power test made with continuous pink noise signal within the frequency range
