Abstract
A loudspeaker arrangement may include a loudspeaker having first and second voice coils to provide motive force for a loudspeaker membrane, and an electric transformer having a primary coil connectable electrically to an electrical power unit, and a secondary coil connectable electrically to the first and second voice coils. The voice coils each may have two first winding ends connected to each other via a first electrical conducting path to form a parallel electrical circuit and two second winding ends connected to each other via a second electrical conducting path. The first electrical conducting path may be connected electrically to a first winding end of the secondary coil via a first electrical connecting path and via an additional first electrical connecting path, which may form a parallel circuit with the first electrical connecting path. The second electrical conducting path may be connected electrically to a second winding end of the secondary coil via a second electrical connecting path and via an additional second electrical connecting path, which may form a parallel circuit with the second electrical connecting path.
