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