Abstract: An audio system comprising a control circuit, at least one loudspeaker and at least one subwoofer for reproducing audio signals at low frequencies. The control circuit comprises an input connector and a bass management circuit that comprises a first filter with a low-pass for pre-filtering audio signals for the subwoofer and a second filter for pre-filtering audio signals for the loudspeaker. The loudspeaker comprises a high-pass filter, wherein in a transition frequency range of the amplitude responses of the first filter and the high-pass filter both filters raise or attenuate the audio signals such that the audio system overall, without considering the second filter, has a wavy amplitude response in the transition frequency range. The second filter however comprises at least one parametric filter that is adapted for flattening the amplitude response in the transition frequency range.
