To improve the reproduction of audio signals, the signal components of a selected audio frequency range (1) of an audio signal are concentrated in a narrower audio frequency range (II). This is achieved by detecting first signal components in the first audio frequency range (I), generating second signal components in the second audio frequency range (II), and controlling the amplitude of the second signal components in response to the amplitude of the first signal components. As a result, dedicated transducers may be used which are particularly efficient in the narrower frequency range. The original frequency range (I) may contain the lower frequency signal components (bass components) of the audio signal.
