A loudspeaker system for obtaining a higher acoustic output and increasing directional output character of the loudspeaker system, the loudspeaker system comprising: - a front loudspeaker enclosure (10, 10') having at least one front loudspeaker (20, 20'), and a closed rear wall; and - a rear loudspeaker enclosure (30, 30') arranged at the rear wall of the front loudspeaker enclosure (10, 10'), the rear loudspeaker enclosure (30, 30') having at least one rear loudspeaker (40, 40'). characterized in that - in the loudspeaker system the front loudspeaker enclosure (10, 10') is in the form of a horn-loaded enclosure having the at least one front loudspeaker (20, 20') and a horn configured to provide a front sound source for radiating a front sound wave, and - the rear loudspeaker enclosure (30, 30') is in the form of a single chamber vented high-pass enclosure having the at least one rear loudspeaker (40, 40') and at least one vent (42, 42') configured to provide a rear sound source for radiating a rear sound wave, and - the front loudspeaker enclosure (10, 10') and the rear loudspeaker enclosure (30, 30') have the same 4th order high-pass transfer function, and - a sound wave path (a) from the front loudspeaker (20, 20') to the mouth of the horn and a sound wave path (b) from the rear loudspeaker (40, 40') to the mouth of the horn of the front loudspeaker (20, 20') have relatively same length and are essentially equal to 1/4th of the average wavelength of a bass region, - such that the front sound wave from the front loudspeaker (20, 20') and the rear sound wave from the rear loudspeaker (40, 40') reach the mouth of the horn in front of the loudspeaker system at the same time and have the same phase and are summed thereby obtaining a considerably higher acoustic output of the bass region in front of the speaker system, and - when the front sound wave from the front loudspeaker (20, 20') and the rear sound wave from the rear loudspeaker (40, 40') are summed at a point close to the rear loudspeaker (40, 40') they are 180° out of phase causing sound cancellation of the rear sound wave. - a front loudspeaker enclosure (10, 10') having at least one front loudspeaker (20, 20'), and a closed rear wall; and - a rear loudspeaker enclosure (30, 30') arranged at the rear wall of the front loudspeaker enclosure (10, 10'), the rear loudspeaker enclosure (30, 30') having at least one rear loudspeaker (40, 40'). - in the loudspeaker system the front loudspeaker enclosure (10, 10') is in the form of a horn-loaded enclosure having the at least one front loudspeaker (20, 20') and a horn configured to provide a front sound source for radiating a front sound wave, and - the rear loudspeaker enclosure (30, 30') is in the form of a single chamber vented high-pass enclosure having the at least one rear loudspeaker (40, 40') and at least one vent (42, 42') configured to provide a rear sound source for radiating a rear sound wave, and - the front loudspeaker enclosure (10, 10') and the rear loudspeaker enclosure (30, 30') have the same 4th order high-pass transfer function, and - a sound wave path (a) from the front loudspeaker (20, 20') to the mouth of the horn and a sound wave path (b) from the rear loudspeaker (40, 40') to the mouth of the horn of the front loudspeaker (20, 20') have relatively same length and are essentially equal to 1/4th of the average wavelength of a bass region, - such that the front sound wave from the front loudspeaker (20, 20') and the rear sound wave from the rear loudspeaker (40, 40') reach the mouth of the horn in front of the loudspeaker system at the same time and have the same phase and are summed thereby obtaining a considerably higher acoustic output of the bass region in front of the speaker system, and - when the front sound wave from the front loudspeaker (20, 20') and the rear sound wave from the rear loudspeaker (40, 40') are summed at a point close to the rear loudspeaker (40, 40') they are 180° out of phase causing sound cancellation of the rear sound wave.
