PRODUCT GRADING (Grade B) - Good Condition > Very light scratches and light signs of use > Refurbished to the highest standards. Retail Box WHAT IS IN THE BOX Planet Audio AC10D 10 Inch Subwoofer PRODUCT DESCRIPTION  A new subwoofer must go through a short but important process of \'break-in\' before it is run under harsh conditions. This will ensure the performance as it has been designed to. The process involves subjecting the subwoofer to no more than low-to-medium volume levels for a number of hours in the enclosure. This will loosen the suspension to prevent the voice coil from overheating. Over-driving the woofer before it has been broken-in, will result in premature failure and poor performance.
