| Abstract: | The speaker power test is an important basic test project in the electro-acoustic enterprises＇ assessment of the production performance of the speakers which they produced. It is also an important basis to judge the speaker actual power that is same as the nominal rated power. This paper introduces the basic principles and methods of loudspeaker power testing which based the recognized speaker power test standard. It presents a detailed specific method from the hardware and briefly discuss on the realization of PC software as well. |
