12″ x 4″ Linear Roll Nomex Spider
12″ x 4″ linear roll spider has a consistent roll or corrugation pattern throughout it’s entire surface. The corrugation shape is uniform, providing a consistent restoring force as the voice coil moves. Typically made from fabric impregnated with stiffening resin, the material choice and treatment affect flexibility and durability. This design offers a linear compliance characteristic, meaning the restoring force remains consistent across the entire range of motion.
Do I need to stack multiple spiders?
Stacking multiple 12″ x 4″ linear roll spiders on top of each other in a subwoofer design offers several benefits. Multiple spiders provide additional support to the voice coil, ensuring it remains centered and stable. This reduces the risk of coil rubbing against the magnet assembly, enhancing overall speaker reliability. The combined stiffness from stacked spiders allows the speaker to handle higher power levels without distortion. This is particularly useful in high-performance audio systems where loud volumes and powerful outputs are required. Stacking spiders increases control over the voice coil’s movement, especially during large excursions. This helps maintain linearity and reduces distortion for clearer sound reproduction. Multiple spiders also improve the damping of the speaker system, reducing unwanted resonances and vibrations. This leads to a cleaner and more accurate audio output, especially at high frequencies.
By stacking spiders with different stiffness characteristics, designers can fine-tune the compliance of the speaker suspension system. This allows for more precise control over the speaker’s performance, optimizing it for specific audio applications. The additional layers of spiders distribute mechanical stress more evenly, reducing wear and tear on individual components. This can extend the overall lifespan of the speaker, making it more durable in demanding environments. In summary, stacking multiple spiders enhances stability, power handling, control over excursions, damping characteristics, customization of compliance, and overall durability, resulting in improved performance and longevity.
