Actually, funny you should mention it. My company did that installation. The residence is in Ibiza, Spain. Between the water views of the Mediterranean and the TV, it makes quite an impression in the flesh.
We are also one of the first IMAX Private Theatre dealers in the U.S. So, if one wants the world's most immersive private theater indoors and the world's most fascinating outdoor residential display, I will be most happy to accommodate.
That is the price of the unit. Installation has to be added to that. Just to give you an idea of the size of size of the task, it weighs one-and-a-half tons and among other construction details to be taken into consideration, the ground installation has to be completely waterproofed. It's a considerable construction project.
