ESD312 - 3-Way Passive Speaker

The ESD312 is a very high output full-range 3-way, passive solution with two bass reflex loaded 12“ woofers, a single horn loaded 6“ mid range and a 1“ compression driver. Housed in a professional robust Baltic Birch cabinet, with a protective polymer paint coating and heavy-duty grille, the ESD312 can be a dedicated close-field DJ Monitor system when used in conjunction with the VHD2.18J Subwoofer and monitor bracket. It can also be applied as a PA system, as an individual full range speaker or as a fill speaker to accompany larger format VHD systems. For added versatility in installation, the ESD312 is supported by dedicated accessories including a vertical bracket enabling a wide range of mounting and deployment options for hanging.
