The Electro-Voice EVA-1151D is a high-power, front-loaded subwoofer module for use with EVA full-range line-array modules. It can be arrayed on top of an EVA full-range array using an EVASG2 standard or EVA-EG2 extended grid, or behind a full-range EVA array using the EVA-CG coupler grid, which allows subs to be flown in the array without increasing trim height. Up to three EVA-1151D subwoofer modules and five full-range modules may be flown in this configuration from a single hang point. The unique acoustic and integrated rigging design of the EVA series also allows for construction of vertical arrays up to eight modules high using any combination of EVA-1151D and/or EVA-2082S modules.
