ABSTRACT:
A speaker enclosure with a pentagonal cross section and sloping sides contains a dynamic damping system located in the lower portion of the enclosure. Speakers mounted in the side walls are always positioned opposite a corner to prevent the production of standing waves. The rearward projection from the speaker and reflections from the walls are directed downward to the dynamic damping system, eliminating the absorptive padding used in prior systems and its inherent loss.
