ABSTRACT:
The invention provides a loudspeaker system having a housing made of a plastic casing and a foam positioned against the interior walls of the casing through a reaction between the foam and the interior wall. The foam increases the stiffness of the walls as well as provides sound damping. Additionally, the foam may create a foam rib between a stud and the casing to support the stud and transfer the stiffness of the stud to a wall of the casing.
