Loudspeaker arrangement

A loudspeaker arrangement, comprising:

• a transducer arranged in a loudspeaker enclosure, the loudspeaker enclosure encloses a rear part of the transducer;
• an aperture-defining structure defines an aperture, the aperture-defining structure is 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 at frequencies within a predetermined wide frequency range;
• the aperture defined by the aperture defining structure is configured to amplify sound at predetermined frequencies or within a predetermined frequency range within the predetermined wide frequency range, and to let sound at all other frequencies within the predetermined wide frequency range pass essentially unaltered;
• and
• the loudspeaker enclosure is sized such that a resonance frequency of the loudspeaker enclosure matches a resonance frequency of the transducer in free air, the resonance frequency of the transducer in free air is below a predetermined threshold.
