EVA-1151D has been designed exclusively for fixed installation applications. The DVX3159A 15” woofer is specially designed for subwoofer duty to provide reliable low-frequency performance with solid impact and low distortion at high sound pressure levels. The enclosure is constructed of 18mm 13-ply birch plywood reinforced with internal steel rigging top to bottom and coated with EVCoat for durability and professional appearance. PI versions are available for indirect outdoor exposure or fiberglass (FG) versions for severe exposure applications. PI and FG versions include the CDG dual-gland-nut input panel cover and stainless steel three-layer grille. The innovative input panel provides a choice of Phoenix/Euroblock connectors, optional CDNL4 cover plate with dual NL4-type connectors or the CSG single-gland-nut plate for use with cable. Enclosure side-panel covers conceal all suspension hardware and provide a smooth, monolithic appearance. In keeping with the modular building-block philosophy behind EVA series loudspeakers, inter-module tie plates included with the EVA-1151D provide for splays of 0° or 5° between subwoofer modules to help accommodate the wide variety of array configurations possible, including stand-alone subwoofer arrays.
