Abstract
A low frequency loudspeaker driver has polygonal diaphragm surfaces. In a first embodiment, the peripheral edge of a loudspeaker driver diaphragm is polygonal, preferably hexagonal or six sided, wherein each of the six peripheral sides are of equal length and meet in radiused or rounded corners. The hexagonal loudspeaker driver is supported within a matching hexagonal section truncated pyramid shaped basket having a hexagonal peripheral mounting flange. The hexagonal woofer of a first embodiment is adapted to be mounted on a planar baffle in a variety of densely packed arrays such that virtually no wasted baffle space is visible between the driver basket peripheral edges. The faceted hexagonal diaphragm shape provides an increase in cone surface area of approximately ten percent as compared to conventional frustoconical woofers having circular peripheral edges.
