Voice Coils are the heart of every subwoofer and loudspeaker. They convert amplifier power into cone movement and sound. Our selection includes multiple diameters, wire types, and configurations to fit a wide range of builds. Choose copper coils for maximum conductivity. Pick aluminum coils for lighter weight and efficiency. Select CCA coils (copper-clad aluminum) for a balance of performance and value.

We also offer formers in aluminum, Kapton, and fiberglass. Each option provides unique thermal and mechanical advantages. Single and dual coil designs give builders, repair shops, and DIY enthusiasts more flexibility. Use them to repair, upgrade, or design custom subwoofers. Built for durability and high power handling, our coils deliver reliable performance in daily systems, competition setups, and everything in between.
