Design and Aesthetics
The LG S40TR features a sleek design that combines functionality with style, making it an appealing addition to any room.

Audio Quality
The audio quality is a significant differentiator between the two models. The LG S40TR, with its 4 channels and Dolby Digital compatibility, promises a cinematic sound experience, especially with its wireless rear speakers. On the other hand, the LG S70TY elevates audio quality further with its Dolby Atmos capabilities, providing a more immersive spatial sound experience. This model also features an industry-exclusive up-firing center channel, which focuses on dialogue clarity, making it ideal for movie lovers. While both soundbars deliver excellent audio, the S70TY stands out for users who prioritize advanced audio technologies.
Connectivity Features
Both soundbars offer convenient connectivity features, but the LG S40TR has an edge in versatility with its WOW Interface. This feature allows users to control both the soundbar and compatible LG TVs using a single remote, simplifying the user experience. The S70TY also includes the WOW Interface, along with rear speaker readiness, ensuring seamless integration with additional audio components. Despite these similarities, the S40TR's wireless rear speakers provide a more straightforward setup without the need for additional receivers, making it easier for users to enjoy surround sound immediately.
Price Comparison
The LG S40TR is currently available for $196.99, while the LG S70TY is priced at $346.99. This means that the S70TY costs approximately $150 more, a significant difference that may influence your decision. If you are budget-conscious and still want to enjoy enhanced sound quality, the S40TR presents an attractive option. However, if you are willing to invest more for advanced features like Dolby Atmos and a more immersive audio experience, the S70TY might justify its higher price.

Its WOW Interface also simplifies control, making it user-friendly for those who may not be tech-savvy. The LG S70TY offers a similarly streamlined experience but shines with its integration with LG's QNED TVs and its ability to project 3D spatial sound. Users who prioritize easy setup and operation may find the S40TR more appealing, while those invested in high-end audio may favor the S70TY for its advanced features.
