This is a two part system designed to accommodate sound for a variety of lobby based events. Each of the three vestibules would have a self-powered speaker attached to each end on a flange that woud allow for some change in direction. They would be addressable from each of the three vestibules so that they would work with different event setups. The two line array speakers are portable and can be placed at a stage or head table to be the primary source for spoken word or light music. The vestibule speakers would then act as delay. These speakers can work independently of the self-powered speakers above the vestibles.
