A loudspeaker arrangement (100) comprises a transducer (14) arranged in a loudspeaker enclosure (10, 12), the loudspeaker enclosure (10, 12) enclosing a rear part of the transducer (14), and an aperture (16) mounted on a front side of the transducer (14) in a direction of propagation of sound emitted by the transducer (14), wherein the transducer (14) is configured to emit sound within a wide frequency range, and at frequencies of above the defined threshold, the aperture (16) is configured to amplify sound at defined frequencies or within a defined frequency range within the wide frequency range, and to let sound at all other frequencies within the wide frequency range pass essentially unaltered, and the loudspeaker enclosure (10, 12) is sized such that the resonance frequency of the loudspeaker enclosure (10, 12) matches the resonance frequency of the transducer (14) in free air, wherein the resonance frequency of the transducer (14) in free air is below the defined threshold.
