Abstract: A drone acoustical transducer for a loudspeaker system has an improved means of interconnecting the generally conical speaker diaphragm and supporting basket. In conventional fashion, the acoustical transducer includes a generally conical speaker diaphragm supported within a vented basket having an open front and a rear wall. The large, front end of the diaphragm is flexibly connected to the front of the basket by means of a supple annulus. The basket has a rear wall having an upstanding boss which is coaxial with the diaphragm and smaller in diameter than the small end of the diaphragm. A flexible spider interconnects the small end of the diaphragm with the boss, allowing full excursion of the vibrating speaker diaphragm. To allow for maximum excursion of the diaphragm, the rear wall of the basket may be concave as viewed from the rear.
