ABSTRACT


Presented is an acoustic low frequency horn for corner placement, radiating backward into the corner cube, where the waves are reflected back into the room, guided by 3 wall-planes out of the corner forming the biggest possible conical horn. Providing a wave path without sudden change in the expansion avoids the formation of a horn mouth and problems therefrom. In consequence it has a high efficiency and needs only a smaller speaker that fits into an enclosure of less than a magnitude smaller size than comparable corner horns. Thereby retaining the excellent reproduction characteristics of an over sized bass horn, but with reduced enclosure size, material and overall cost. It comes without cutoff frequency effect and can play down to the limit of human audibility without losing its characteristics at lowest frequencies.
