Power handling capability of speaker system

    The speaker's power handling capability is an important technical parameter, which represents the speaker's ability to withstand long-term continuous safety work, understand the speaker's power handling capability. First, we must understand how the speaker driver is bad, and the driver's damage mode has two kinds:

    One is the voice coil overheating damage (voice coil burned, over heat distortion, the ring breakdown, etc.), and the other is the drive of the diaphragm displacement exceeds the limit value, so that the speaker's conical diaphragm / or its surrounding elastic parts damage, usually occurs in the low frequency signal contains many large amplitude.

    Sound signal is a sine wave signal, but a random, these random signals available three to numbers, effective value (RMS) also known as root mean square value, is to a measurement result of signal peak amplitude of the sinusoidal signal, which is close to the average value, basically representative of the signals of the heating energy.

   The peak value (Peak) is the maximum signal level, the peak level is greater than 3dB, for the music signal, the peak value is important, the peak value is 6dB, the peak value is 4 times the effective value of AES2-1984.

    The speaker power handling capability is measured the technical parameters according to pink noise signal (AES2-11984) treatment for 2 hours after permanent changes in the electrical and mechanical performances of not more than 10%.
