A loudspeaker output correcting device operable under control of a control element, and comprising a first loudspeaker for outputting a first test signal, a second loudspeaker for outputting a second sound signal including a second test signal such that the phase of the second test signal is almost the same as that of the first one and when the second test signal is combined with the first one, the power characteristic is a constant value, sound collecting element for collecting the outputted first and second test signals, computing element for computing the difference between the first distance between the first loudspeaker and the sound collecting element and the second distance; between the second loudspeaker and the sound collecting element from the spectrum of the combined signal produced by combining the collected first and second signals, and correcting element for correcting the output relative characteristics of the first and second loudspeakers.
