My room is small. It's treated but because of layout constrictions (doors, windows, and equipment), the treatment isn't ideal. I can't get bass traps in all the places I really need them so I'm still dealing with some recording issues. I've been thinking that I should add some kind of gobo to the mix and
found this on GIK Acoustic's site. Two is probably what I'll need but there's no savings in buying both at the same time, so I ordered one for now (bright red with white veneer).
