9.25″ x 3″ Semi Cupped Progressive Roll Spider

9.25″ x 3″ Semi Cupped Progressive Roll Spider

 9.25″ x 3″ progressive spider features a varying roll or corrugation pattern, with compliance increasing (becoming stiffer) as displacement increases. The inner rolls are softer, while the outer rolls are stiffer. Made from Nomex fabric impregnated with stiffening resin, the design allows for variations in stiffness across the spider. This results in a non-linear compliance characteristic, meaning the restoring force increases as the voice coil moves further from its rest position. This design helps to maintain stability and precision during extreme movements, ensuring consistent performance.

9.25″ x 3″ Progressive roll spider offers an extended dynamic range, handling greater excursions and higher power levels due to the increasing stiffness, making them suitable for high-power applications. They are durable, better suited for handling extreme forces and high-stress environments without damage. Additionally, they provide enhanced control of the voice coil at high excursion levels, reducing the risk of mechanical failure.
