Improvements in and relating to loudspeaker spiders

The spider 20 extends across the gap between the chassis (4, fig 1) and the voice coil (10, fig 1) and comprises a plurality of legs 36, each leg 36 extending radially across at least a portion of the gap. Each leg 36 comprises three regions 36a, 36b, 36c. Each region has a respective cross-sectional area. The cross-sectional area of the second region 36b is smaller than the respective cross-sectional areas of the first and third areas 36a, 36b. When the diaphragm is in a neutral position the cross-sectional shape of each leg 36 follows a line which varies in height with respect to a reference plane (a, fig 3), said line comprising first, second and third curves. The curves are alternately convex and concave. Thus, the spider may have legs 36 having an 'm' or 'w' shaped profile. Each leg may carry a mass damper (544, fig 7).
