A loudspeaker apparatus has an improved reproduction characteristic of signals of small sound volumes. The loudspeaker apparatus includes a small-signal loudspeaker unit operable to output first signals in the range of a predetermined level or below of the input audio signals, with a characteristic in which the linearity of output frequency with respect to input signals is substantially secured in the range of the predetermined level or below; and a large-signal loudspeaker unit operable to output signals in the range of a predetermined level or above of the input audio signals, with a characteristic in which the linearity of output frequency with respect to input signals is substantially secured in the range of the predetermined level or above, wherein the linearity of an input-output characteristic is secured regarding both small-amplitude and large-amplitude signals.
