1. A loudspeaker, comprising:

  • a magnetic structure;

    a voice coil magnetically suspended about the magnetic structure and configured to move axially about the magnetic structure in response to an electric signal provided to the voice coil;

    a speaker cone having a central portion coupled to the voice coil;

    a spider configured to maintain a position of the voice coil about the magnetic structure when no electric current is provided to the voice coil, wherein the spider has a first portion opposite a second portion such that the first portion faces toward the speaker cone, and the second portion faces away from the speaker cone; and

    a wire flexible in a first plane that is parallel to axial movement of the voice coil and substantially inflexible in a second plane that is orthogonal to the first plane such that, during axial movement of the voice coil, the wire flexes in the first plane and does not substantially flex in the second plane, wherein the wire conductively couples an input terminal to the voice coil, and wherein the wire is at least partially adhered to a surface of the second portion of the spider.
