Abstract

A dome-type moving coil driver for a loudspeaker has a diaphragm (28) with a dome (32) and an annular surround (34), the surround producing substantial radiation at frequencies below the active range of the dome. The surround (34) is of folded annular shape and its outer diameter is greater than 2.3 times its inner diameter. The dome is of diameter at least 1.5 inch (3.8 cm) and is of either partial spherical or parabolic shape. <IMAGE>
