Abstract:
A loudspeaker system comprising:at least one loudspeaker drive unit; at least one loudspeaker enclosure for housing said loudspeaker drive unit(s), said loudspeaker enclosure(s) having at least one resonating chamber(s) therein, wherein said loudspeaker drive unit(s) produces at least one standing wave in said resonating chamber(s); at least one internal resonance control structure, said internal resonance control structure being positioned within said loudspeaker enclosure to form a tapering cross-sectional area within said at least one resonating chamber(s) tapering outwardly from an apex proximal to said loudspeaker drive unit(s) to substantially diffuse said standing wave; wherein said at least one loudspeaker drive unit comprises two low- or mid-frequency loudspeaker drive units and a high frequency loudspeaker drive unit, wherein said internal resonance control structure comprises two perforated dividers and one solid divider, and wherein said two perforated dividers and said solid divider are configured within said resonating chamber such that each of said perforated dividers is substantially parallel to each other and is substantially equidistant across the center of each of said low- or mid-frequency loudspeaker drive units and does not cross said high frequency loudspeaker drive unit, and said solid divider is substantially perpendicular to said two perforated dividers across said high frequency loudspeaker and not across said low- or mid-frequency loudspeaker drive units.
