The Audio Visual system I designed for my church. Built from white oak lumber and white oak veneer on 1/4 inch thick Masonite. The equipment rack system and deck support are fabricated from one inch steel angle iron. The white painted sheetrock in the first picture is the original AV system as you can see the new construction more than doubles the size. As usual the finish is MinWax clear poly. Total cost of materials was a little under six hundred dollars. the new equipment upgrade was nine thousand dollars.
