The S20A is more compact and focuses on providing essential sound enhancements, while the S70TY aims for a more immersive home theater experience with advanced features.
Design and Aesthetics
In terms of design, both the LG S20A and S70TY feature LG’s new crest design, providing a sleek and stylish look that complements modern TVs. The S20A is compact and designed to fit seamlessly in smaller spaces, while the S70TY is tailored to match the LG QNED series, making it an ideal choice for those with compatible TVs. The S20A's smaller size may appeal to users looking for a discreet upgrade, whereas the S70TY's design not only focuses on aesthetics but also ensures it nests perfectly beneath larger QNED models, enhancing overall setup cohesion.
Audio Quality
The LG S70TY excels in audio quality with its 3.1.1-channel configuration and Dolby Atmos technology, delivering a more dynamic and spatial sound experience. This soundbar is particularly noted for its up-firing center channel, which enhances dialogue clarity, making it ideal for cinematic experiences. On the other hand, the S20A offers a solid audio upgrade with its Dolby Digital support and passive radiator for bass enhancement. While the S20A provides a satisfying sound for everyday use, the S70TY’s features cater to audiophiles seeking a more immersive listening experience.
Connectivity Options
Both soundbars offer convenient connectivity options, but the S20A stands out with its single-cable setup using HDMI Arc, reducing cable clutter. This feature allows for seamless integration with LG TVs, making it easy to enhance sound without a complicated installation. The S70TY, while also compatible with LG TVs, includes advanced features like wireless rear speaker support for a more expansive soundstage. Users with a focus on simplicity may prefer the S20A, but those looking for a more feature-rich setup will appreciate the connectivity capabilities of the S70TY.
Smart Features
The LG S20A includes the LG ThinQ App, which allows users to customize audio settings easily from their smart devices. This feature is excellent for users who want to fine-tune their listening experience. Both soundbars also feature the WOW Orchestra and WOW Interface, enabling users to control their soundbar and LG TV with one remote. However, the S70TY enhances the audio experience further with its ability to connect to wireless rear speakers, providing a more comprehensive home theater setup.
Price Comparison
The LG S20A is priced at $116.99, making it a budget-friendly option compared to the S70TY, which is priced at $346.99. This price difference of $230 is significant, especially for casual viewers who may not require advanced features. At about 66% less, the S20A offers a great solution for those looking to improve their TV sound without breaking the bank, while the S70TY justifies its higher cost with superior audio technology and features.
User Experience
In terms of user experience, the S20A appeals to those seeking straightforward sound enhancement with minimal setup. Its compact design and easy connectivity make it an excellent option for everyday users. The S70TY, however, targets a more immersive experience geared toward home theater enthusiasts. The added features, such as the up-firing center channel and wireless surround sound options, create a more engaging audio environment, but they may require a more complex setup.
Which should you buy?
Ultimately, your choice between the LG S20A and the LG S70TY depends on your specific needs and budget. If you're looking for an affordable sound upgrade that is easy to set up and compact, the S20A is a fantastic option at $116.99. However, if you want a more immersive audio experience with advanced features like Dolby Atmos and wireless rear speakers, the S70TY, despite its higher price of $346.99, might be worth the investment. Consider your viewing habits and budget to determine which soundbar will best enhance your entertainment experience.
