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、12 dB/oct. or higher slope high-pass filter.
5、Xmax= [(winding depth – magnetic gap depth)/2] + (magnetic gap depth/3).
6、Thiele-Small parameters are measured after a preconditioning test.
7、Woofer power test made with continuous pink noise signal within the frequency range.Compression driver power test made with continuous pink noise signal within the range from the recommended crossover frequency to 20kHz.
