I have a small tracking/mixing room with plenty of bass traps already installed in all the usual locations, first reflections, corners, sides, cloud. They are all 703 unfaced, 4 inch thick, spaced 2 inches off the wall. The room has a drop ceiling and carpeted floor. The room is a bit dead as is to be expected in a 12x9x7 space. I was reading some old threads about adding a little RFZ or cardboard facing to get a little of the highs back.

I did a search on this and I want to double check to make sure I'm reading it correct before I do anything or if it will do more harm then good to do add the facing in such a small space.

1. Should I do this in such a small room or just leave the traps the way they are?

2. If it's a good idea, Which are the best traps to face with RFZ? If I read the threads correct, the rear corners are ok as well as the rear sides but I should not do it at first reflection points. I'm not sure about the rear wall traps. What about the cloud over the desk? From my mirror test the rear section over my head is a first reflection point? Should a just add the RFZ to the front?

I have been living with the deadness of the room, it's not the worst I have ever heard, but I'm always trying to tweak it a bit.

On a side note, doing the clap test I found that I tamed the flutter with the traps, but there was a weird metallic ringing in the room. After walking around a bit I found it was coming from a can of compressed air sitting on a shelf. It's amazing the little things that can trip you up.
