How do you recoil subwoofers?

Recoiling a subwoofer involves replacing the voice coil and ensuring it is properly aligned within the speaker's magnetic gap. First, remove the speaker cone and surround, then extract the damaged voice coil. Install a new voice coil, making sure it is centered, and reassemble the speaker by carefully reattaching the cone and ensuring all components are securely in place. It's important to use appropriate materials and techniques to maintain sound quality.
