A sound wave emanating from the transducer is conveyed via the acoustic duct portion expanding in a horn-like manner to the frontal chamber, and a sound wave emanating from the opposite side of the transducer is conveyed either to a closed space (20) or directly to the frontal chamber. The subwoofer can be adjusted without altering the external dimensions of the loudspeaker enclosure, utilising the entire volume of the loudspeaker enclosure, so that the frontal chamber is tuned by altering the size of the frontal chamber and/or the size of the aperture in the frontal chamber.
