Abstract: A combination loudspeaker and sign holder having a housing which has enlarged flat parallel end walls joined by narrow end walls. Within the housing is an acoustic horn having a vertical axis and horn end walls diverging downwardly and outwardly. The horn end walls are secured to the housing side walls, and the horn side walls are constituted by the housing side walls. Atop the horn is a speaker which radiates downwardly through the horn and the open bottom of the housing. Preferably the horn end and top walls are formed by a single bent strip of corrugated plastic and the housing is formed of the same material. Tabs in the housing allow it to be suspended from a store ceiling, and a sleeve bearing advertising material may be fitted over the housing. Alternatively, advertising material may be attached to the sides of the housing.
