If you want that look in real life I can do it, but by the time me and the joiner and the plasterer and the decorator have finished you shouldn't expect much change out of ten grand.
To pull all that off, we'd need to build a false wall, and install some Amina sound panels, and AV amp to drive them and act as a hub, then cut in to the floor to run power and signal cabling and bring it up at a fixed point behind the rear leg. You'd also need a proper AV control system, not Harmony.
Consideration for access, ventilation, existing cable re-routing would be part of the project.
What you're seeing in the picture is a mock-up rather than a practical installation. Presuming that the image on screen is genuine rather than a Photoshop edit, then as an installer I'd look at the Parquet flooring and think twice before messing with it. For that reason then, in the photo shoot mock-up they use a thick rug all the way to the back wall. By the way, the back wall isn't real either. It's a set piece, very much like stage or movie sets. Behind that wall there'd be a laptop with various art images for the shoot.
