ABSTRACT:
An ultra low frequency transducer or subwoofer for automotive speaker systems with a rectangular or square or otherwise polygonal diaphragm. The basket of the transducer has a correspondingly polygonal front, which preferably is sized to be substantially coextensive with the front of the speaker housing or cabinet. In this way, air displacement in the subwoofer is maximized for a given size of enclosure, and thus so is the loudness of the speaker. The preferred diaphragm is concave, and the transducer preferably includes a convex surround with pleated corners. For increased durability, trusses are formed in the diaphragm.
