Abstract
A speaker system includes a speaker box and a speaker mounted thereon. A bass reflex duct is provided in the speaker box at a position corresponding to an approximate center portion of the speaker. In addition, another duct is provided around the speaker in the speaker box. The bass reflex duct is arranged inside of a duct so that the bass reflex duct and the duct overlap each other. The speaker system is arranged to efficiently direct the back pressure of a speaker to the bass reflex duct and greatly increases the sound pressure in resonance even when a compact speaker box is used.
