摘要
A loudspeaker includes an acoustical enclosure having an internal wall dividing the enclosure into first and second subchambers, an electro-acoustical transducer having a vibratable speaker cone mounted in an opening in the internal wall of the acoustical enclosure, an internal vent in the internal wall of the acoustical enclosure for pneumatically coupling the first and second subchambers, a first external vent in a wall of the first subchamber for pneumatically coupling the first subchamber to an exterior environment outside of the acoustical enclosure, and a second external vent in a wall of the second subchamber for pneumatically coupling the second subchamber to the exterior environment, a ratio of the acoustic masses of the internal vent to the the second external vent being approximately 3/1 to 7/1, and a ratio of the acoustic masses of the first external vent to the second external vent being approximately 15/1 to 30/1.
