ABSTRACT:
An inner suspension system for a speaker assembly comprising a center spider, an intermediate spider, and a linear spider. The system reduces distortion of the output from the speaker and increases axial integrity of the movement of the cone. The center spider and intermediate spider are disk shaped and are each attached to the frame of the speaker assembly and to different points on the voice coil former. The linear spider, on the other hand, is cylindrically shaped and is attached to the pole piece of the magnetic motor structure, and the cone converges upon the other end of the cylindrically shaped linear spider.
