[QUOTE="Haunz, post: 5070393, member: 576010"] Are you really going to argue that a motor is a poor heat sink because there is a thin layer of air between it and the coil.. then state in the next sentance that the same air is the main method of cooling ? Clearly, the material in a motor structure has a much greater heat capacity and thermal coefficient then air.. and it also provides a great deal of surface area for heat to disapait from.. No doubt the air moving in and out of the gap is the main source of cooling to a voice coil; but the thermal mass and surface area of the motor [I]does[/I] effect power handeling of a woofer... Anyone who has handled a large driver after it has recieved a healthy amount of power for any significan't period can attest to the amount of heat that is given off by the motor..
