Abstract: A loudspeaker housing which is a one-piece casting or is assembled of two or more separately cast sections is obtained by pouring into one or more mold cavities a mixture of three components, namely a hard first component (e.g., particles of sand with a grain size of 0.1 to 3 mm) having a high specific weight, a second component which has a viscosity of between 150 and 10,000 mPa.s (such as a twin-component adhesive or a grouting compound), and a relatively soft but heavy third component (such as granulated rubber tires and/or polyvinyl chloride and/or polyethylene). The sound damping characteristics of the thus obtained loudspeaker housing are superior to those of housings which are made of wood, plastic or ceramic material.
