PURPOSE: A speaker system is provided to increase a particular frequency band in a single speaker in comparison with average sound pressure by changing a bass frequency band. CONSTITUTION: A speaker system includes a voice coil(20) for receiving an electric signal from an amplifier. The voice coil includes a first and a second coil parts(C1,C2) in order to output variably a particular frequency band. The first and the second coil parts are wound around a bobbin(30), respectively. The first coil part of the voice coil is formed to receive AC signals of the amplifier. The second coil part of the voice coil is formed to receive the AC signals of the amplifier through a filter circuit including an impedance, a capacitor, and a resistor.
