Overview
The Samsung HW-S811D is an ultra-slim 3.1.2ch soundbar designed for anyone who wants a major upgrade to their TV's sound without a bulky setup. At just 39.9mm deep, it sits neatly under a TV or mounts flush on the wall, making it a strong fit for wall-mounted TVs, minimal living rooms, and bedrooms where space is tight.
Despite its slim profile, the HW-S811D packs 10 speakers and true 3.1.2-channel sound with wireless Dolby Atmos and DTS Virtual:X, delivering overhead, multidirectional audio without extra HDMI cables. A dedicated wireless subwoofer adds deep bass, while Samsung Q-Symphony lets the soundbar and a compatible Samsung TV play in sync for a fuller sound experience.
SpaceFit Sound Pro automatically tunes the sound to the room, and Active Voice Amplifier keeps dialogue clear even at lower volumes. With Wi-Fi, Bluetooth 5.2, Apple AirPlay, Chromecast, Spotify Connect, and built-in Alexa, this soundbar covers both TV audio and everyday music streaming.

Buying Guide
The HW-S811D is built for anyone upgrading from weak TV speakers who doesn't want a bulky soundbar taking over the room. Its 39.9mm profile slides neatly under most TVs or mounts flush to the wall, while still delivering true 3.1.2-channel sound with dedicated up-firing speakers for genuine height effects with Dolby Atmos and DTS Virtual:X content.
SpaceFit Sound Pro removes the guesswork from setup by automatically tuning the sound to the room, and Active Voice Amplifier keeps dialogue intelligible during quieter scenes without needing constant volume adjustments. Paired with a compatible Samsung TV, Q-Symphony lets the TV and soundbar speakers work together for noticeably fuller sound.
Beyond movies and TV, built-in Wi-Fi, Bluetooth, AirPlay, Chromecast, and Spotify Connect mean this soundbar doubles as a capable everyday music speaker, and Game Pro mode adds a more directional, competitive edge for console and PC gaming.
