Provided are an array speaker system and a method of implementing the same. The array speaker system includes a group setting unit setting one or more combinations of a plurality of speakers included in an array speaker system into at least one group according to a predetermined adjustment factor, a signal assignment unit dividing an input signal into at least one sound source signal according to the adjustment factor and selectively assigning the divided sound source signal(s) to the set group(s), a sound adjustment unit adjusting a sound source signal to be output through speakers within the group according to sound source characteristics of the group, and a signal output unit outputting the adjusted sound source signal through the speakers within the group. Using the array speaker system, sound adjustment and sound output optimized for each frequency band can be obtained during output of a sound source signal having a broad range of frequencies, and a near-field effect that distorts an output sound source signal can be prevented. Moreover, stereo and multi-channel effects can be obtained and the directivity of the array speaker system can be improved.
