請求の範囲第１項記載のスピーカシステム。[Claims for Utility Model Registration] (1) Attenuating the level of a predetermined frequency band of a supplied audio signal in accordance with a predetermined attenuation characteristic and outputting this as a main audio signal, which is substantially based on the predetermined attenuation characteristic of the audio signal. a signal processing means for outputting a sub-audio signal at a level corresponding to the attenuation; a basic electro-acoustic converting means for converting the main audio signal into sound and radiating the sound in a fixed direction; and converting the sub-audio signal into sound. A speaker system comprising sub-electroacoustic converting means that converts the sound and radiates the sound in a direction different from the fixed direction. (2) The speaker system according to claim 1, wherein the predetermined frequency band of the audio signal is a middle range and a high range.
