Design and Build: Compact Style With a Flush Back

The Sony HT-S400 adopts a compact, flush-back design that favors a streamlined appearance in living spaces. The enclosure emphasizes minimalist junctures and clean edges, reducing visual bulk while maintaining functional access to controls. Construction materials prioritize rigidity, with a smooth exterior that minimizes reflections and fingerprints. Its form supports discreet placement, whether wall-mounted or shelf-supported, without obstructing adjacent components. Design aesthetics align with contemporary living-room decor, delivering subtle presence rather than focal prominence. Wireless pairing of the subwoofer and soundbar contributes to a clutter-free setup, reinforcing the overall emphasis on neat cable management and spatial efficiency.
Audio Performance: 2.1 Channel Immersive Sound and Dialogue Clarity
