4 Loudspeaker Impedance
... Loudspeakers are typically specified with nominal impedance, often 8 Ohms or 4 Ohms, although other values are possible. The actual impedance of a typical loudspeaker can vary widely from this rating. In the exercise we shall examine the impedance of two different permanent magnet-voice coil type tr ...
