The ARIA LIGHT is a small-sized 2-band shelf-top speaker system that uses the W 100 S 8 OHM mid-bass unit and the G 20 SC 8 OHM dome tweeter. In smaller rooms and if used as a shelf-mounted unit, the system has a considerable bass foundation which means that a separate subwoofer is not required. However, if coupled with a good powered subwoofer, the range of tonality of far larger hi-fi speakers is achieved.
