Audio's S-series speakers feature coaxial driver units, which are designed to eliminate the phase difference issues commonly found in traditional speakers with separate tweeters and woofers. This reduces sound distortion and enhances audio fidelity. The S-series speakers deliver more precise soundstage positioning, allowing listeners to perceive the location of sound sources more clearly. Thanks to the excellent synchronization between the high and low-frequency drivers, these speakers provide smoother and more natural sound reproduction.
