ABSTRACT:
An integrally formed ported reflex horn comprises an outer housing having a plurality of side walls disposed about a central axis, an open discharge end and a second closed end, oppositely disposed to the open end. The horn also includes a compression driver reception member, for rigidly maintaining a conventional compression driver within the hollow interior of the horn housing, and sound wave guide structure which defines a plurality of ports and a divider for splitting sound waves exiting the throat of the compression driver into a plurality of constituent sound waves of substantially equal sound pressure levels. The constituent sound waves are redirected toward the housing open end as they travel through respective ports and are recombined into a single wave front after exiting the ports upstream of the housing open end.
