We look at the load presented to audio amplifiers by real transducers. We consider the power losses in class-AB and class-D amplifier topologies, and determine that in order to predict efficiency it is necessary to consider the amplifier/transducer combination. The ability of the class-D amplifier to recycle quadrature load current offers new ways to improve efficiency
