An electronics/heat sink housing (26) used in combination with a loudspeaker or powered speaker having an enclosure (24), a passive radiator (50), and an electronics package. The electronics/heat sink housing (26) includes a planar back plate, a top plate, two side plates, and a bottom connector plate. The housing (26) is mounted directly onto a rear panel (30) of the speaker enclosure (24) over the electronics package and passive radiator (50) of the speaker. A plurality of slots are formed within the electronics/heat sink housing (26), preferably along the side plates and top plate of the housing (26), where they are bent relative to the back plate. A plurality of larger slots (56) also may be formed along the side plates of the housing (26). The total area of these slots is greater than the area of the passive radiator (50), so that the enclosure (24) does not interfere with air movement and sound pressure wave propagation from the passive radiator (50). Air movement caused by the passive radiator (50) serves to enhance the thermal cooling of the electronic components. Because of its efficient design, the overall depth of the speaker is minimized, enabling it to fit on a conventional bookshelf. The planar back plate may be positioned against a wall or other solid surface without a reduction in sound output.
