Sonos Beam Ultra Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Dedicated height channels (7.1.2) for Dolby Atmos, not only virtual processing
- ✓A dedicated centre channel for dialogue
- ✓Can add a matching wireless subwoofer later
- ✓Can grow into true surround with optional rear speakers
- ✓HDMI eARC carries lossless Dolby TrueHD and Atmos from the TV
- ✓Wi-Fi streaming with AirPlay 2, Spotify Connect
- ✓Room correction tunes the sound to where it is placed
- ✓Dialogue enhancement and a night mode
- ✓Voice assistant built in (Sonos Voice Control)
- ✓Compact at 29.53 in wide - fits small TVs and tight spaces
- ✗No DTS:X, so DTS soundtracks play without their height layer
Channels and Surround Sound
The 7.1.2 badge means 7 ear-level channels (left, centre, right and 4 for width or surround), 1 subwoofer channel, 2 height channels firing at the ceiling. It decodes Dolby Atmos.
Subwoofer, Rear Speakers and Mounting
A subwoofer is optional - the bar connects to one wirelessly but does not come with it. Rear surround speakers are optional, so it can become a true surround system later. Wall-mountable: Yes (bracket sold separately).
Connections
The Sonos Beam Ultra has HDMI eARC to the TV - the connection that carries lossless Dolby TrueHD and Atmos from the TV's own apps and inputs; USB-C input.
Streaming, Control and Sound Modes
Wi-Fi (2.4, 5.0 GHZ), with AirPlay 2, Spotify Connect, TIDAL, Amazon Music, Apple Music; Bluetooth; voice control: Sonos Voice Control built-in; app control (Sonos app (iOS, Android)); no remote in the box. Sound features: dialogue enhancement, night mode, room correction.
Size and Which TV It Suits
The bar measures 29.53 x 2.56 x 4.13 in (W x H x D), or 750 x 65 x 105 mm, and weighs 6.35 lbs. It is no wider than the screen of a 40-inch TV (34.9 in wide) or larger, which is where a soundbar looks in proportion. At 2.56 in tall it should clear the bottom of most TVs sitting on their own feet.
