The Recone Assembly consists of a pre-assembled cone, surround, and voice coil that will be bolted into the L7XS motor and Basket Assembly, assuring perfect cone and voice-coil alignment. Because there is no glue utilized in the recone process, the cone can be replaced in minutes should failure occur in the field. Alignment pins are included. *The L7XS-Series supports re-coning with ANY IMPEDANCE of L7XS Recone Kit. For example, if you purchased an L7XS with 1-Ohm dual voice coils, you may re-cone using a 2-Ohm L7XS kit.
