In order to properly evaluate a loudspeaker amplifier, it is useful to test its performance under realistic conditions. This implies a load that emulates the complex impedance of an actual loudspeaker driver with its interacting mechanical resonances. A loudspeaker emulator is therefore a useful tool to replace a fixed resistor. Results from an experimental emulation validate the utility for small signals at low frequencies. The design allows the resonant frequencies to be changed by tuning two resistors. Even though the emulation does not exactly match an actual driver, suggestions are provided to improve the approximations.
