The invention relates to a bass loudspeaker enclosure. In order to be able to use enclosures of small dimensions with two but possibly also more bass loudspeakers and still ensure high sound quality, at least two loudspeakers are arranged inside the enclosure, the baffles of these loudspeakers limiting approximately equally large parts of the enclosure cavity and also enclosing a space between themselves which opens into a sound exit opening, corresponding to its cross-section in an outside wall of the enclosure.
