Abstract: A loudspeaker mounting plate having metal rods embedded in a body in such a way that both rigidity and internal damping are maximized. A circular hole is included to allow for the mounting of a loudspeaker. Two sets of metal rods are utilized, the first being placed partially under the loudspeakers frame for maximum surface hardness, and the second being used for bracing the width of the plate. The use of two materials with different properties results in a structure that is highly resistant to vibration.
