ABSTRACT:
A loudspeaker and enclosure assembly, comprising: a load bearing member exhibiting good thermal conductivity; at least one loudspeaker mounted on the load bearing member and in thermal engagement therewith; and, an enclosure having walls formed of rigid light-weight material mounted on the load bearing member to enclose the at least one loudspeaker, whereby the assembly is easily moved and mounted and thermal energy generated by operation of the loudspeaker is effectively dissipated through the load bearing member. The enclosure may be a rigid foam-filled member defining a generally funnel-shaped bore therein to form a horn for the loudspeaker, whereby a modular construction of interchangeable integrally formed enclosures and horns can be achieved.
