Abstract:
1. A sound projector comprising: a cone reflector having a base and a central axis aligned on a radiant axis; a plurality of horns having middle frequency mouths, the middle frequency mouths being disposed radially around the cone reflector forward from the base of the cone reflector along the intended radiant axis with the middle frequency mouths oriented to direct sound energy toward the cone reflector; the cone reflector being shaped to cooperate with the middle frequency mouths for reflection of sound energy forward along the radiant axis; and multi-part low frequency horn extenders located at each middle frequency mouth, the multi-part low frequency horn extenders including a first surface extending from along a portion of the middle frequency mouth to the base of the cone reflector, wedges positioned between each middle frequency mouth and oriented radially around the intended radiant axis and a reverse flare section extending from along a portion of the middle frequency mouth furthest forward along the intended radiant axis and folded away from the radiant axis.
