Abstract: The invention is directed to a tackable/acoustical wall panel having a peripheral frame including a top rail, a bottom rail, opposed side rails and a dividing rail bisecting the panel into a first cavity and a second cavity. The dividing rail extends at a height where a work surface would be attached to the panel. The first cavity has a substantially rigid first septum mounted therein in order to restrict sound transmission through the panel. The first septum has opposing rigid front and back surfaces. A tackable inner layer is secured to the first septum. The second cavity has a substantially rigid second septum mounted therein in order to restrict sound transmission through the panel. The second septum has opposing rigid front and back surfaces. A decorative cover is secured to the frame and extends over the first cavity and the second cavity.
