ABSTRACT:
Shown, in the application, is a novel and extremely cost effective method to replace traditional and contemporary baffles and enclosures used for preventing the cancellation and consequent radiation of lower frequencies from loudspeakers. The space occupied for the added beam element to accomplish this task is smaller than the loudspeaker itself and adds little to the overall size of the loudspeaker system. With this simple element, baffle size, bidirectional, equaphase reproduction down to and including the fundamental loudspeaker resonance, is obtained.
