A realistic clean room with light grey/white walls and light grey wood laminate flooring. A large flat-screen TV mounted directly on the wall in the center. Two tall black floor-standing speakers positioned symmetrically on either side of the TV. Two black subwoofer boxes sitting on the floor in front of each speaker. A center channel speaker mounted in the wall below the TV. A small grey rug on the floor in the foreground. Recessed ceiling spotlights. Very clean, minimal, uncluttered room. No furniture. Photorealistic interior photography, bright and well-lit, shot straight-on facing the TV wall. Style matches a real hi-fi audio showroom or a clean modern living room speaker demo setup.
