Abstract
A ceiling-mounted loudspeaker includes upper and lower sound-directing structures having walls acting as a radial horn to provide a wide included angle of coverage for sound energy generated by a loudspeaker driver assembly having a piston for directing generated sound energy upwardly into the horn. The lower structure further has a continuously convex bottom configured and dimensioned to define a diffraction path for at least some of the sound energy exiting the output mouth of the radial horn, so that the convex bottom acts as a downwardly-directed diffractor. The radial horn and convex bottom together produce an oblate spheroid of sound energy affording a substantially uniform amplitude of sound within a large finite horizontal plane at the level of a listener.
