5.87″ x 2″ Flat Linear Roll Spider

5.87″ x 2″ Linear Roll Spider 

The 5.87 x 2 Spider is a flat linear roll spider designed for subwoofer recone and repair applications. Furthermore, it features a consistent corrugation pattern throughout its entire surface. As a result, the restoring force remains uniform across the full range of voice coil motion.

Typically, spiders like this are made from fabric impregnated with stiffening resin. This material choice directly affects flexibility and durability. In addition, the linear compliance characteristic of this 5.87 x 2 Spider ensures a consistent restoring force across the entire range of motion.

Do I Need to Stack Multiple Spiders?

Stacking multiple 5.87 x 2 Spiders provides additional support to the voice coil. Consequently, this keeps the coil centered and reduces the risk of rubbing against the magnet assembly. Moreover, the combined stiffness allows the speaker to handle higher power levels without distortion.

Stacking also increases control over voice coil movement during large excursions. Therefore, the speaker maintains linearity and reduces distortion for cleaner sound reproduction. In addition, multiple spiders improve damping and reduce unwanted resonances.

Fine-Tuning Compliance

By stacking spiders with different stiffness characteristics, designers can fine-tune suspension compliance. This allows for more precise control over speaker performance. Furthermore, the additional layers distribute mechanical stress more evenly. As a result, the additional layers reduce wear on individual components and improve overall durability.

• Spider Compliance: 0.25mm/50grams
