I used to have to do this years ago with certain rap clients when the Meyer HD1s wouldn't go loud enough. It was easy with the Trident console we had, as the speaker set switches on the monitor section were latching. I heard that after I left that studio, the next guy they had turned the HD1s up so loud that they vibrated off the stands and fell onto the floor, which required being sent back to Meyer to be repaired. I heard that when they got them back, they tied them down to the stands with ratchet straps
Sorry for the OT post.
