Design and Build Quality
When it comes to design, both soundbars feature LG’s new crest design, providing a sleek and stylish appearance. The S20A is compact, making it suitable for tight spaces, while the S40TR includes wireless rear speakers, enhancing its home theater setup. The metal grill on both models helps keep dust and debris out, ensuring longevity and consistent sound quality. With its larger structure, the S40TR promises a more robust presence in your entertainment setup, while the S20A focuses on being unobtrusive.
Sound Quality
The sound quality of both models is impressive, but they cater to different audio experiences. The S20A provides a rich bass experience through its passive radiator, complemented by Dolby Audio for an immersive listening experience. This soundbar is designed for users who want an upgrade from standard TV sound without a complicated setup. In contrast, the S40TR features 4 channels and includes a wireless subwoofer and rear surround speakers, delivering a more cinematic sound experience. This model is ideal for those who prioritize a surround sound system that fills larger rooms.
Connectivity Options
Connectivity is a significant factor for both soundbars. The S20A is equipped with HDMI Arc, allowing easy single-cord connectivity with LG TVs, simplifying setup and reducing clutter. It also supports LG’s WOW Interface, which enables users to control the soundbar and TV with one remote. On the other hand, the S40TR offers similar connectivity options but enhances them with wireless rear speakers, eliminating the need for extra wiring. Both models utilize the WOW Orchestra feature, which harmonizes audio from the soundbar and connected LG TV for an enriched experience.

The LG S20A is priced at $116.99, making it a more budget-friendly option compared to the LG S40TR at $196.99. This price difference of $80 reflects the additional features and capabilities of the S40TR, particularly its surround sound capabilities and extra speakers. For users on a tighter budget or those who don’t require a full home theater setup, the S20A represents a solid investment. However, for those seeking a more immersive audio experience, the higher price of the S40TR may be justified.

Which should you buy?
Choosing between the LG S20A and the LG S40TR ultimately depends on your audio needs and budget. If you’re looking for a compact, budget-friendly soundbar that can enhance your TV audio without the clutter of extra components, the S20A is an excellent choice at $116.99. However, if you desire a more immersive home theater experience with surround sound capabilities and are willing to invest $196.99, the S40TR is likely the better option.
