I am a technician in a theatre who doesn't use their monitors for their intended purpose. Instead they sit in the storage closet collecting dust. The other day my teacher brought up an idea of using the monitors as surround speakers placed at the back of the house. I already have the location picked out but how would i go about hanging or mounting them safely. If your wondering the brand and model they are EV Eliminator monitors, not more than one year old. Any suggestions would be greatly appreciated.
