Video room module

The big Windows become screens

This strange object is actually a surround speaker, and the round ball at the bottom is a subwoofer.

You can't put a speaker behind the screen, but you can use the screen to deliver sound. If you have enough speakers, you can make sound only where it is needed.

White wall is bad solve, the light of whole house basically relies on the reflex of natural light and wall, can imagine wall is not luminous so but become angry material only.
