8″ x 3″ Linear Roll Subwoofer Spider

Stacking multiple 8″ x 3″ linear roll spiders in a subwoofer design provides significant performance benefits. Multiple spiders give the voice coil additional support; as a result, it stays centered and stable throughout movement. This reduces the chance of coil rub against the magnet assembly, thereby increasing long-term reliability.

The combined stiffness of stacked spiders allows the subwoofer to handle higher power levels without distortion. This is particularly important in high-performance audio systems where extreme output is expected. During large excursions, stacked spiders also help maintain linearity and reduce distortion, which leads to cleaner and more accurate sound reproduction.

In addition, stacking improves damping characteristics, helping to control unwanted resonances and vibrations. Consequently, the system delivers tighter response and reduced coloration, especially noticeable at higher frequencies.

Furthermore, designers can mix spiders with different stiffness ratings to fine-tune compliance. This flexibility means builders can optimize suspension behavior for both SPL and SQ applications. Moreover, by spreading mechanical stress across multiple spiders, the suspension lasts longer and performs more consistently, even in demanding environments.
