Sennheiser AMBEO Soundbar Plus vs LG S90TY 5.1.3 Soundbar

The Sennheiser AMBEO Soundbar Plus is the stronger pick for pure movie sound. Its 7.1.4 array with AMBEO virtualization and dual built-in 4-inch subwoofers creates a wider, more enveloping stage from a single bar, and owners rate it higher. The LG S90TY is the better fit if you own an LG OLED B, C or G series TV: WOW Orchestra and WOWCAST tie the bar to the TV wirelessly, and the included wireless subwoofer handles low bass without stressing the bar. The Sennheiser is bigger, heavier and needs more room, while the LG leans on its subwoofer and TV integration.

  • Choose the Sennheiser AMBEO Soundbar Plus if you want one self-contained bar with the widest virtual surround, deep built-in bass and room calibration, and you don't need a separate subwoofer.
  • Choose the LG S90TY if you own an LG OLED B, C or G series TV and want wireless WOWCAST, WOW Orchestra and a dedicated wireless subwoofer for less.

Questions and answers

Which is better for movies?
The Sennheiser AMBEO Plus, thanks to its 7.1.4 virtualization and dual built-in subs. The LG S90TY is close and adds a real wireless subwoofer, but its surround stage is narrower.
Which has better bass?
The LG S90TY's separate wireless subwoofer moves more air and goes deeper in practice. The Sennheiser's dual built-in subs reach 38Hz but can't match a dedicated sub's output.
Do I need an LG TV for the S90TY?
No, it works with any TV over HDMI eARC or optical. But WOW Orchestra and WOWCAST only work with LG OLED B, C and G series TVs.
Which is easier to fit in a room?
The LG S90TY. Its bar is slimmer, and the subwoofer can go on the floor. The Sennheiser is larger and heavier, though it is wall-mountable.
Is the Sennheiser worth stepping up to?
Yes if you want one bar with the widest virtual surround and no separate sub. If you own an LG OLED and want a dedicated sub, the LG is the more sensible match.
Which supports more streaming and voice options?
The Sennheiser: AirPlay 2, Chromecast, Spotify Connect, TIDAL Connect, plus Google Assistant, Alexa and Siri. The LG offers Chromecast and Alexa only.
