The VLS 15 (EN 54) is an 800-Watt passive column array loudspeaker ideally suited for challenging acoustic and architecturally sensitive spaces where background/foreground music and speech reinforcement is required. Applications include airports, train stations, conference centers, houses of worship, stadium concourses, museums, theme parks and hotels. The heart of the loudspeaker system is its asymmetrical vertical dispersion, which gently shapes the acoustic coverage towards the lower quadrant of the vertical axis.
