Drive unit is in absolute beautiful condition. No issues period. Fully functional. Removed from a fully functioning pair of Studio 100 V2 speakers. Comes from a smoke free/pet free home. I have four of these available. Unit will be professionally packaged and insured for safe transit. I will be shipping UPS Ground unless buyer objects. I ship to lower 48 only. I have other Studio 100 V2 drive inits and parts listed. These were my personal speakers. I know them well. Again...beautiful condition.
