Low-Frequency horn loaded systems for pi/2 radiation are designed employing push-push operated dual membrane loudspeakers, closely mounted in parallel against each other. Tree Axis Symmetrical and efficient horn mouth loading is transformed to a symmetrical and uniform membrane cone loading. By doubling loudspeaker diaphragm, and respectively the horn throat, lower horn cut-off frequency was achieved with the same extension rate, besides acoustic power doubling. Two such corner horn systems could be stacked together for quarter space pi-loading, with important usage in front-of-stage subwoofer applications. Four horn systems are grouped together over the floor or on the ceiling for 2 pi-radiation. Finally, eight such systems could be united for full space low-frequency radiation.
