Abstract
The fundamental resonant frequency of a loudspeaker marks its useful low-frequency limit. Its values may be determined by plotting the electrical impedance of the loudspeaker against frequency. This was done for a loudspeaker under various loading conditons. The graphs obtained yield useful information about the loudspeaker’s mass, compliance, and other parameters.
