Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that when a reproduction sound of a surround channel interferes with a reproduction sound from a front channel speaker driver, a sense of clear localization cannot be obtained, similarly to reflection on the wall or the like. SOLUTION: A multi-channel signal reproduction apparatus includes: a first speaker box to which a speaker driver is mounted for front L channel, front center channel and front R channel reproduction and which is installed at a lower side of a television screen; a second speaker box to which a surround L channel and surround R channel speaker driver is mounted and which is installed at an upper part of the television screen; and a virtualizer which performs signal processing on a reproduction signal inputted to the surround L channel and surround R channel speaker driver and localizes a sound source at a place different from the space where the surround L channel and surround R channel speaker driver is installed.
