Abstract:
1. A loudspeaker system comprising: an enclosure including a first exterior wall, a second exterior wall disposed opposite the first exterior wall, and an interior, wherein the first and second exterior walls separate the interior of said enclosure from an exterior of the loudspeaker system; a transducer at least partially disposed within the interior of said enclosure; a first port extending from an opening in the first exterior wall to an end of said first port in the interior of said enclosure; and a second port extending from an opening in the second exterior wall to an end of said second port in the interior of said enclosure, wherein said transducer is at least partially disposed in an interior air space that is the same interior air space occupied by the interior ends of said first and second ports, and wherein the respective ends of said first port and said second port are separated by a predetermined distance within the interior of said enclosure, such that acoustic energy from the interior air space exits said enclosure through said first and second ports approximately simultaneously and air in said first and second ports and between the interior ends of said first and second ports operates substantially as a single acoustic mass.
