An investigation of the equivalent circuits of loudspeakers in vented boxes shows that it is possible to make the low-frequency acoustic response equivalent to an ideal highpass filter or as close an approximation as is desired. The simplifying assumptions appear justified in practice and the techniques involved are simple. The low-frequency performance of a loudspeaker can be adequately defined by three parameters, the resonant frequency f,, a volume of air Va,, equivalent to its acoustic compliance, and the ratio of electrical resistance to motional reactance at the resonant frequency Qe. From these three parameters, the electroacoustic efficiency v can be found also. A p
