Is there any place online where you can purchase all the marque signs I am looking for? (Dolby Digital, DTS, THX etc..) I like the black and gold signs and I want to try and get them all the same size. It would be so much easier to just purchase them from one location. Home Depot and Lowes no longer carry soundboard. Is there something on the market that will serve the same accoustical purpose? Boards are easy to install and cover with fabric. I want to stay away from batting. I am going to use it on the lower half of my room and leave the upper half drywall with a set of columns with batting and insulation in them at the first reflection point.
