ABSTRACT:
A subcompact woofer speaker cabinet system provides high volume low frequency response, long speaker life without overload and sound projection over considerable distances. This is achieved by mounting a damped speaker diaphragm within a cabinet enclosure having a single projection opening for soundwaves expanded by an internal panel forming a common wall between substantially an exponentially diverging output horn and a converging pathway from the speaker front into the output horn, wherein the panel first compresses the wavefront from the speaker diaphragm into the horn and then expands the wavefront to project low frequency audio outwardly from the cabinet system. Lower audio frequencies in the order of 100 Hz or less are faithfully reproduced and projected in a cabinet having major dimensions only slightly larger than the diameter of the speaker.
