A diagnostic circuit for a treble loudspeaker of a loudspeaker combination of a low-frequency output stage, and a method for diagnosing the functionality of the treble loudspeaker. In order to determine the functionality of the treble loudspeaker with relatively little complexity and high reliability, a diagnostic circuit is provided that comprises an HF signal-generating device for outputting an HF voltage signal, at least one terminal for a loudspeaker combination, a measuring resistor that, upon connection of the loudspeaker combination to the terminal, forms therewith a voltage divider circuit, and a measurement device for measuring a complex measured voltage dropping in the voltage divider circuit and for ascertaining a condition of the treble loudspeaker of the loudspeaker combination. |
