Abstract: The present invention relates to a method and a circuit for testing a tweeter. The tweeter is part of a loudspeaker system. The method includes the steps of: applying a high-frequency voltage signal to one terminal of the tweeter, whereby the high-frequency voltage signal is generated by first electronic means. The method also includes applying a constant voltage signal to the other terminal of the tweeter, whereby the constant voltage signal is generated by second electronic means. The method includes measuring a current (Iload) that flows through the tweeter into the second electronic means and determining a connect/disconnect state of the tweeter from the value of the current.
