Abstract:
A loudspeaker enclosure, comprising:a hollow semicircularly curved casing having a cylindrical top, the cylindrical top having an open front end for introducing a driver thereto and a back end connecting to a first end of a sloping back semicircular side, the back semicircular side having a second end connected to a first end of a semicircular bottom surface, the semicircular bottom surface having a second end connected to a first end of a front semicircular side, the front semicircular side having a second end connecting to the front end of the cylindrical top thereby forming a semicircular front baffle of the enclosure; a series of interconnected flat baffles forming an internal baffle placed inside the hollow semicircularly curved casing, the series of flat baffles peripherally bordered by the hollow semicircularly curved casing and enclosed with side panels forming a labyrinth, an enclosed circuitous pathway of a constantly increasing cross section, the labyrinth subsequently splitting and terminating into an exit port for each split pathway, the side panels together with the hollow semicircularly curved casing forming the enclosure's external walls; a compression chamber inside the cylindrical top of the semicircularly curved casing behind the driver, the compression chamber having a back open end facing the sloping back semicircular side to allow sound waves coming from the driver to travel down the labyrinth and prevent back waves from reflecting back to the driver; a base unit having an internal and external side wall and a transverse bottom panel for holding and stabilizing the enclosure; means for sealing the internal baffle to the side panels and the semicircularly curved casing; means for sealing the side panels to the semicircularly curved casing; means for leveling the loudspeaker enclosure; and, means for assembling the entire loudspeaker enclosure together.
