Improvements in and relating to loudspeaker spiders

A loudspeaker (1) comprising a diaphragm (2), a voice coil (10) mounted on the diaphragm (2) to move with the diaphragm (2), a chassis (4), and a spider (20) is disclosed. The spider (20) extends across a gap between the chassis (4) and the voice coil (10) and comprises a plurality of legs (36), each leg (36) extending radially across at least a portion of the gap. The diaphragm (2) is configured to move from a neutral position to an extended position. When the diaphragm (2) is in the neutral position the cross-sectional shape of each leg (36) follows a line which varies in height with respect to a reference plane, said line comprising first, second and third curves, the second curve being located in between the first and third curves. Either the first and third curves are convex and the second curve is concave, or the first and third curves are concave and the second curve is convex. Thus, the spider (20) may have legs (36) having an 'm' or 'w' shaped profile in at least one region of the leg (36).
