|The versatile MG-1D multipurpose grid allows M1D/M1D-Sub loudspeakers to be flown or ground stacked. MG-1D also provides a transition from the bottom of an M2D/M2D-Sub array to an M1D/M1D-Sub array. Up to 16 M1Ds (or the equivalent weight of M1Ds and M1D-Subs) may be suspended from single or multiple rigging points of appropriate rating. In addition the MD-1D can be used to fly M2Ds and/or M2D-Subs. Up to seven M2Ds (or the equivalent weight of any combination of M2Ds and M2D-Subs) can be flown from the MG-1D grid at a 7:1 safety factor, or 10 M2Ds at a 5:1 safety factor.
