A speaker system has a speaker unit with a vibration plate of a corn type, a horn and a diffuser. The horn is disposed such that a small-diameter opening thereof is positioned inward from a front opening of the vibration plate, and an outer surface of the horn is arranged along an inner surface of the vibration plate from the small-diameter opening to form a first acoustic path. The diffuser has a base portion, a front end portion and an outer peripheral surface extending therebetween, and is disposed such that the base portion is positioned inward from a front opening of the horn and opposed to the small-diameter opening of the horn. The diffuser has a specific shape such that the outer peripheral surface expands along an inner surface of the horn from the base portion to form a second acoustic path. The expanding outer peripheral surface of the diffuser is then narrowed toward the front end portion of the diffuser.
