The DS123Bis designed for use in conjunction with a subwoofer system, in high level club playback and cabaret reinforcement systems or any nearfield application where flat response and wide coverage are required at high sound pressure levels. Its physical construction and packaging have been optimized for easy permanent installation. The DS123B’s horizontal configuration permits unobtrusive hanging around the corners of a dance floor or above the perimeter of the stage.
