Abstract
A loudspeaker including an acoustic radiator configured to emit front-side acoustic radiation from a front side and rear-side acoustic radiation from a rear side; a housing that directs the front-side acoustic radiation and the rear-side acoustic radiation; and a plurality of sound-emitting vents arranged in the housing. The plurality of sound-emitting vents includes a first sound-emitting vent arranged in a first end of the housing and a second sound-emitting vent in a second end of the housing. A first distance between the first and second sound-emitting vents defines a first effective length of a first loudspeaker dipole. The plurality of sound-emitting vents further includes third and fourth sound-emitting vents arranged in the housing. A second distance between the first sound-emitting vent and the third and fourth sound-emitting vents defines a second effective length of a second loudspeaker dipole. The second effective length is shorter than the first effective length.
