1. Throw ten or more big heavy blankets over the cabinet. First, make a "T" from two pieces of 3/4 inch plywood, and use 3M Dual-Lock to attach it to the top of the cabinet, lined up with the right or left speakers. Make sure the bottom of the T goes all the way to the back of the cabinet so there's as much of the T as possible attached to the top of the cabinet, because the blankets are heavy. The top of the T should be about two feet wide and stick out about 2 or 3 feet from the front of the cabinet. Then hang the blankets from the floor in back of the cabinet, over the top of the T to the floor in the front. This gives you the space for the microphone. Once you get the mic adjusted, throw on some more blankets from one side of the cab to the other. It's not as quiet as a box but it sounds a lot better.
2. You'll get a better tone by just throwing a bunch of moving blankets over the cabinet - it won't be as quiet as a box, but it takes the volume down a lot.
