Heat dissipation is the ability to transfer the heat away from a component into the air to prevent damage to the speaker. Heat is the process of energy transfer from one system to another due to thermal contact. In cold climates, houses with their heating systems form dissipative systems. In spite of efforts to insulate such houses to reduce heat losses to their exteriors, considerable heat is
. lost or dissipated, from them, which can make their interiors uncomfortably cool or cold. For the comfort of its inhabitants, the interior of a house must be maintained out of thermal equilibrium with its external surroundings. In such house, a thermostat, a device capable of starting the heating system when the house's interior falls below a set temperature, and of stopping that system when another higher set temperature has been achieved, is used. Thus, the thermostat controls the flow of energy into the house, that energy eventually being dissipated to the exterior. You can find more information here: http://en.wikipedia.org/wiki/Heat
