A loudspeaker arrangement comprising a loudspeaker provided with a membrane and an acoustical absorbent in which a sintered polymeric porous material is provided so that an air space in the back of said membrane is separated, by the sintered polymeric porous material, from ambient air. Method of damping low frequencies of sound characterised by the separation of an air space behind a membrane of a loudspeaker from ambient air by means of sintered polymeric porous material. |
