Overview of the LG S20A and Roku Wireless Subwoofer

The LG S20A 2.0 ch. Soundbar is priced at $116.99, while the Roku Wireless Subwoofer comes at $129.00, making the LG soundbar about 13% cheaper than the Roku subwoofer. Each product offers unique features that cater to different audio experiences, so understanding their strengths can help you make an informed choice. The LG S20A focuses on enhancing TV sound with its immersive audio features, while the Roku Wireless Subwoofer aims to provide powerful bass to complement home audio systems.

Design and Build Quality

The LG S20A boasts a sleek and stylish design with a metal grill that not only enhances aesthetics but also keeps dust out. This soundbar is compact, making it easy to fit in various setups without taking up much space. In contrast, the Roku Wireless Subwoofer is designed to be versatile in placement, allowing it to be positioned up to 30 feet away from the TV. While the subwoofer does not have the same sleek look as the LG soundbar, its ability to blend into different environments offers flexibility. Both products prioritize ease of use, but they cater to different preferences in design.

Audio Quality

The LG S20A excels in delivering rich sound through its Dolby Digital capabilities, ensuring that you don’t miss any details while watching your favorite shows or movies. Its passive radiator enhances bass output, creating an immersive audio experience. The Roku Wireless Subwoofer, on the other hand, is engineered to provide powerful bass with a peak of 150 watts. While the soundbar handles overall audio well, the subwoofer specifically enhances low frequencies, making it ideal for users who enjoy a more robust sound profile. This differentiation in audio focus can significantly influence your choice depending on your listening preferences.

Connectivity Options

The LG S20A offers seamless connectivity with LG TVs through its WOW Interface, allowing you to control both the soundbar and the TV using a single remote. This feature simplifies the user experience, especially for those who prefer a minimalist setup. Additionally, the soundbar connects with just one HDMI Arc cable, reducing cable clutter. On the other hand, the Roku Wireless Subwoofer's setup is entirely wireless, eliminating the need for cables altogether. This can be particularly appealing if you prefer a clean and cable-free space. The choice between these two products may come down to whether you prioritize easy integration with LG devices or a completely wireless solution.

User Experience

With a bestseller rank of 2046, the LG S20A is well-regarded for its user-friendly features. It includes the LG ThinQ App, which allows users to customize equalizer settings directly from their smart devices. This level of control can enhance the listening experience significantly. Meanwhile, the Roku Wireless Subwoofer, ranked 9139, simplifies the user experience by requiring no additional remotes; your existing Roku remote is sufficient. The automatic software updates also ensure that the subwoofer maintains optimal performance over time. Each product aims to provide a straightforward user experience, albeit with different approaches.

Compatibility

The LG S20A is designed to work seamlessly with select LG TVs, making it a perfect match for users who own LG products. Its WOW Orchestra feature allows for a harmonious audio experience by combining sound from both the soundbar and the TV. Conversely, the Roku Wireless Subwoofer is designed to work specifically with the onn. Roku Smart Soundbar, meaning it requires that particular soundbar to function. This could limit its compatibility for users who do not already own the corresponding Roku soundbar, potentially making the LG S20A a more versatile choice for those with varied devices.

Price Comparison

Currently, the LG S20A is priced at $116.99, while the Roku Wireless Subwoofer is priced at $129.00. This places the soundbar at about $12.01 lower than the subwoofer, or approximately 9% less expensive. When considering the price difference, the LG S20A may offer better value if you are looking for a standalone audio solution without needing additional equipment. In contrast, if you already have or plan to purchase the onn. Roku Smart Soundbar, the subwoofer may be worth the investment for enhanced bass.

Which should you buy?

Deciding between the LG S20A 2.0 ch. Soundbar and the Roku Wireless Subwoofer ultimately comes down to your specific audio needs and existing equipment. If you are looking for a cost-effective, all-in-one solution that enhances TV sound with rich audio features, the LG S20A is an excellent choice. However, if you already own the onn. Roku Smart Soundbar and seek to add depth and power to your audio experience, the Roku Wireless Subwoofer would be the better option. Each product has its strengths, making your personal audio preferences and setup the key factors in your final decision.
