AES UK Section Event – What are those peaks, anyway? Exploring the electrical impedance of loudspeakers

Loudspeaker drivers are reciprocal transducers. Their main task is transforming an electrical (audio) signal to a mechanical force, then to a sound wave. In the opposite direction, any change in the acoustic or mechanical domains is reflected in the electrical input impedance of the driver. Therefore, a driver can also be used as a sensor to investigate the features of the enclosure in which it operates.


Beginning with the classical description of loudspeakers as equivalent electrical circuits, Principal Research Engineer, Roberto Magalotti from Bowers & Wilkins will show how this idea can be applied to practical cases, consider the level of accuracy that can be achieved, and discuss additional insights that could be gained from the peaks in the impedance graph of a loudspeaker system.
