Short answer: the LG S90TY for better sound quality, the LG S70TY for the lower price. The LG S90TY ranks #8 of 16 soundbars with a subwoofer, rated 3.5/5, at $999.99. The LG S70TY ranks #9, rated 3.4/5, at $285.75, $714.24 cheaper.
Why pick the LG S90TY: A bar with a real wireless sub that suits both TV and music, with clear dialogue and a wide front stage. It streams over Wi-Fi as well as Bluetooth, which the LG S70TY cannot. The catch: Without rear speakers the height effect only works for sounds in front, and RTINGS found Samsung Q800 bars such as the Samsung HW-Q800F wrap the room with Atmos far better.
Why pick the LG S70TY: The bar and wireless sub blend smoothly, giving a balanced sound with controlled bass that What Hi-Fi rated four stars. The tradeoff: A single up-firing driver gives only a hint of height, so the surround effect is limited without LG’s optional rears.
Buy the LG S90TY when sound quality outweighs the price for you, and the LG S70TY when the price outweighs sound quality instead.
