Abstract
A bass-reflex loudspeaker system in which, by the addition of a corrective network (7) to an arrangement of a transducer (1) accommodated in a bass-reflex enclosure (2), which transducer is dimensioned such that it cannot be bass-reflexed by means of the bass-reflex enclosure, it is possible to simulate a set-up of an imaginary transducer which is housed in the said bass-reflex enclosure and which has a much greater frequency range H.sub.f (f) than the aforesaid arrangement.
