Abstract
A dynamic equalizer circuit is disclosed for the driver system of an electro-mechanical transducer such as a loudspeaker. The circuit provides an improved or leveled audio output and includes a protective arrangement which protects the transducer against damage from being overdriven. The protective arrangement includes a sensor which produces a continuous protective control signal based upon operating characteristics of the transducer such as transducer motion or temperature or fatigue.
