A wall panel is a piece of material that is commonly flat and used on walls in an exposed and visible manner. Wall panels are used for different purposes whether it being for visual design purposes or insulation and soundproofing. Although there are no specific sizes for panels it is often suggested for it to be 24 inches by 8 feet in order for a singular panel to be easily moved and transported.
The FM studio soundbox is heavily soundproofed and insulated allowing recording sessions to be carried out inside while other music is being played for the rest of the BELOWGROUND retail area.
