I'm looking for any one with experience that can lead me in the right direction about room treatments. I have been looking at some of the Auralex roomanator kits and bass lenrds. I was told that foam doesn't do anything acoustic wise, so I was looking at the Owens Corning 705 FRK and thinking about doing 48"X24"X2" panels. I want to frame them with wood, but what would be a good backing and front covering. Any input would be appreciated or give some suggestions on something. Thanks
