Short answer: the Yamaha True X Bar 50A. It ranks #7 of 16 soundbars with a subwoofer by sound quality, rated 3.5/5, at $199.99; the LG S70TY ranks #9, rated 3.4/5, and costs $269.99, so there is not much of a tradeoff to weigh.
Why pick the Yamaha True X Bar 50A: The bar and its wireless sub throw a broad, well-defined soundstage for movies, and Expert Reviews praised how articulate the sub sounds. It streams over Wi-Fi as well as Bluetooth, which the LG S70TY cannot. Watch for: Overhead effects are modest, and music sounds flat compared with movie playback.
The case for the LG S70TY: The bar and wireless sub blend smoothly, giving a balanced sound with controlled bass that What Hi-Fi rated four stars. Watch for: A single up-firing driver gives only a hint of height, so the surround effect is limited without LG’s optional rears.
Buy the Yamaha True X Bar 50A. It is rated higher for sound quality than the LG S70TY and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
