I no longer have a place on my wall for these. I have them mounted on a sheet of plywood painted black. The DTS plaque is the same one found on the dts website. The Dolby Digital plaque however is only found in movie theatres. It is much larger than the one on their website. 21 X 9.5 inches. It reads DD sound system installed in this auditorium. Both plaques are in impeccable condition. Asking $100 OBO for plaques and their mounting.
