One of the important parameters for selecting speakers is the size of the speaker's power. It should be pointed out that there is a big difference between domestic and foreign speakers. This is because the definition of power is different. The nominal power of the average speaker is rated at.
Rated power or rated noise power, is the speaker can work for a long time without exception. The general test uses pink noise signal, through the specific filter, in the rated frequency range for testing. According to the IEC standard, the speaker should be measured in 100 hours of continuous work without exception. By the way, the U.S. EIA standard is set to test time of 8 hours, but also different filters.
The maximum noise power is different from the rated power, which is the ability of the speakers to withstand the large input power of a short time, the test time is only a few seconds or a few minutes. The average maximum noise power is 2-4 times the rated power.
