LG S70TY Soundbar vs LG S90TR Soundbar

The S90TR is the stronger buy for most people. It is a true 7.1.3 system with 13 speakers, 670 W, a bigger 8-inch subwoofer and wireless rear speakers, so it creates real surround behind you. The S70TY is a 3.1.1 bar with one up-firing height channel, a 16 cm sub and 400 W, and it wins on size: it is slim, light at 3 kg and nests under a QNED TV on a stand. Owners rate the S90TR well at 4.6 out of 5, and reviewers consistently favor rear speakers for movie immersion.

  • Choose the LG S70TY if you have a smaller room, want a slim bar that sits under an LG QNED TV, and prefer one remote with WOW Orchestra over rear-channel surround.
  • Choose the LG S90TR if you want genuine 7.1.3 surround with wireless rear speakers, deeper bass and Wi-Fi streaming, and have room for a larger sub and rears.

Questions and answers

Which is better for movies?
The S90TR. Its wireless rear speakers and three up-firing drivers put sound behind and above you, which the S70TY's single height channel cannot match.
Which is better for a small room or bedroom?
The S70TY. Its slim 3 kg bar and small sub fit tight spaces, while the S90TR needs room for a large sub and two rear speakers.
Do I need an LG TV to use WOW Orchestra?
Yes. WOW Orchestra and the one-remote WOW Interface only work when paired with a compatible LG TV. Both bars still work over HDMI eARC with other TVs.
Which has better bass?
The S90TR. Its 8-inch subwoofer weighs 10 kg against the S70TY's 16 cm sub, and it delivers more output at 670 W versus 400 W.
Is the S90TR worth stepping up to?
If you watch a lot of films and can place rear speakers, yes. You get real surround, more power and Wi-Fi streaming. If you mainly want clearer TV dialogue in a compact setup, the S70TY is enough.
Which lasts longer?
Both carry a one-year LG warranty and use similar electronics. The S90TR's metal body may hold up better cosmetically, but neither is outdoor-rated or waterproof.
