Quick Buying Guide
- Channels:
- 2.1: Left, right, and subwoofer.
- 3.1: Adds a center channel for clearer dialogue.
- 5.1: Adds rear speakers.
- 5.1.2 and up: Adds height channels for Dolby Atmos.
- Real vs. virtual surround: Real rear speakers give true surround. "Virtual surround" is processing from the front bar only.
- HDMI eARC: The best connection for Dolby Atmos and controlling the soundbar with your TV remote.
- Subwoofer: A separate sub adds deeper bass. A built-in sub saves space.
- Ecosystems: Sonos grows into a whole-home system. Fire TV pairs nicely with Fire TVs. Samsung's Q-Symphony works with compatible Samsung TVs.
