Recone & Drop-In Kits restore subwoofers by replacing worn or damaged soft parts. Each kit includes all the components needed for a rebuild. They fit specific subwoofer brands and models to ensure proper alignment. Recone kits give builders a full set of parts for standard rebuilds. Drop-in kits act as an easier version of a recone kit, arriving pre-assembled for faster installs with minimal adjustment. Builders, repair shops, and DIY enthusiasts use these kits to bring subs back to life in daily drivers, custom builds, and high-power SPL systems.
