These Artcoustic speakers are thin (2.56") and hang on the wall as if a painting. They measure 25.5" by 19.65". Artcoustic in Denmark verified them by their serial numbers to have originally sold for $1,829 each. They were purchased unused six years ago from a developer who had intended to put them into a high end spec house. They've had moderate use and been in a child free, pet free, smoke free home and powered by a AV system for the television. There are a few minor scratches on the back where they were mounted to the wall.
