Abstract

The loud-speaker enclosure has a box with loud-speakers. The inside of the box is covered with lead or lead alloy which can reflect audible frequency sound and has low susceptibility to vibrations. The lead or lead alloy layer can be from 0.5 to 1.5 millimeters thick. The box is made of reconstituted wood. Classical type loud-speakers may be fitted to the box. A vent may also be used. A tension wire, as shown parallel to the height or to the width of the box may be fitted to reduce vibrations.
