My new monitors will be facing a flat, hollow, wall which is about 3m away. There is a faux-suede couch against the wall. I had some pieces of foam lying around; I thought I could glue these down to some MDF/plywood/whatever's cheap and make an acoustic panel for above the couch.
It ended up being a bit small - about 117x63 cm (46x24 inches.) I could place it either horizontally or vertically at that size. Should I build the panel or am I just wasting my foam?
I'll get a pic of the wall space & the couch when I get home. I'm open to alternate configurations for the foam pieces too.
