This is a refurbished product that has been professionally rebuilt here at Sundown Audio. It comes with a non-doa warranty only. That means they are guaranteed to work when you receive it but no further warranty afterwards. Let us know within 24 hours of delivery if this product has an issue. We will not warranty any refurbished subwoofer after that time. These potentially have scratches & scuffs on the magnets/motors and will not be in new condition.
