ABSTRACT:
A loudspeaker is provided in which the outer diameter or foot of the spider is over molded with a standoff formed of a plastic material in an injection molding tool so that the spider and standoff form an integral unit. The standoff, in turn, is glued or otherwise affixed to the frame of the speaker to provide accurate centering of the voice coil relative to the magnetic gap of the motor structure.
