Engineered for use in permanent installations, the loudspeaker enclosure and faceplate are constructed of multilayer glass composite, providing extreme structural strength. A three-layer WeatherStop grille provides weather-resistance to the internal components, while all exposed hardware is stainless steel or powder-coated aluminum extrusion. Six 1/2-13 mounting points are included.
