The 1/2 Grid Silent White is the middle-strength grid cloth: enough diffusion to turn a hard source into a big soft wrap without giving up all your punch. The silent construction means it won't crinkle and flap into the sound mix when the wind comes up or a fan is on the floor. Sizes run from the 4'x4' slip-on up to a 20'x20' overhead, all sewn in the USA by LA Rag House. If a diffusion order lists one rag, it's usually this one.
