OK. I can do that. I don't fully understand about the corner bass traps. Are you talking about building a 2'x4'x4" panel and putting it at an angle in the corner leaving an air gap behind it, or are you saying I need to cut the OC 703 at a triangle shape and "fill" the entire area floor to ceiling?
I understand about the floor to ceiling of the bass traps and the gobo's need to be 4" thick to be behind the desk and monitors.
I have a question about the monitors also, but I will start a new thread since it is a different subject. I think I'm getting enough information to build on. Thanks to all who have replied.
Actually they are an Alesis DM 10 set. I had a 6V set with all mesh heads before I got into the recording side of music, but I sold them I'm an idiot! The Alesis are ok, but nothing like the Roland's I had.
