A speaker system in which it is possible for power amplifier heat radiation and satisfactory audio characteristics to coexist. The power amplifier, and other components which are sources of heat, are arranged in an air flow convection path that is formed in a curved path from a lower bass reflex port toward an upper bass reflex port of a speaker box. The heat is exhausted (radiated) to the outside from the interior air space of the speaker box by the air flow and air from outside is introduced into the interior air space with good efficiency. In addition, the power amplifier includes a heat sink. The heat sink includes gaps that are formed between each of a plurality of fins which are opened in a vertical or diagonal direction such that the air flow convection path passes through the gaps.
