Typically, on a loudspeaker driver specification, an input power rating is specified. Most often, there are 2 numbers reported –average power and peak power specs. Although the essence is the same, an engineer sourcing a driver for a given application: telecom, fire and safety, telematics, among others, has a slightly different perspective than your average … Continue reading “Input Power”

In the piston range of a driver (before the cone exhibits oscillations other than those induced by the motion of the voice coil in the magnet), a loudspeaker acts as a high pass filter (HPF). The resonant frequency of a speaker, f0 (pronounced: F-naught), is the frequency below which a loudspeaker is increasingly unable to … Continue reading “Resonant Frequency”

In electrical parlance, impedance, Z, is the characteristic of a device that causes a reduction in the amount of current, I, for a given voltage, V, in a circuit. It’s generally described by the equation: Typically, this impedance is characterised by two components: resistance and reactance. Since resistance is the same under DC or AC … Continue reading “Loudspeaker Impedance”
