Abstract: A loudspeaker system with three loudspeakers (LF, LR, LB), includes a first and a second amplifier (BF, BR), each of which amplifies a channel of an audio signal. The outputs of the amplifiers (FDA, FIA; RDA, RIA) are in phase opposition, wherein the outputs of the amplifiers (RDA, FIA; RDA, FIA) are each connected to the inputs of the first and second loudspeakers (LF, LR). The outputs of the amplifiers (RDA, FIA; RDA, FIA) are also connected to the inputs of the third loudspeaker (LB). A high-pass filter (HP) and a low-pass filter (TP), which are used to partition the audio signal, are connected in parallel. As the amplifiers, bridge output stages (BF, BR) are provided. The output of the high-pass filter (HPA) is connected to the inputs of the two bridge output stages (BF, BR). An inverter (IF, IR) is provided in each case between the output of the high-pass filter (HPA) and one of the inputs of the bridge output stages (BF, BR).

Abstract: A sub-woofer arrangement for the reproduction of bass tones is provided in an armrest of a seat of a passenger car. The sub-woofer arrangement has a sound outlet orifice positioned so as to face a dashboard when lowered in a first position and be unobstructed when raised into a second position in a recess within the seat.
