The X12-125F-GRID grid is rated for a maximum hang of up to nine X12-125F subwoofers when suspended from a single middle point and up to 16 subwoofers when hung from two lateral points on the same spreader bar. The modular design of the grid includes all parts needed for quick assembly and disassembly. Model the array in Electro-Voice line-array configuration software before deployment to ensure that the configuration is valid and safe.
