Price Comparison

The LG S70TY 3.1.1-Channel QNED TV Matching Soundbar is priced at $346.99, while the TCL S45H 2.0 Sound Bar for Smart TV comes in at a much lower price of $79.99, making it about 77% cheaper than the LG option. This significant price difference makes the TCL soundbar an attractive choice for budget-conscious consumers who still seek quality audio for their home entertainment setup. However, the LG soundbar justifies its higher price with advanced features and a design specifically tailored for LG QNED TVs, appealing to those who prioritize a seamless aesthetic and enhanced audio experience.

Audio Quality

When it comes to audio quality, the LG S70TY offers a more sophisticated sound experience with its 3.1.1 channel configuration and Dolby Atmos technology. This soundbar is designed to deliver immersive 3D spatial sound, making it ideal for viewers who appreciate detailed audio, particularly in action-packed films or dramatic dialogues. In contrast, the TCL S45H features a simpler 2.0 channel layout but still provides impressive sound quality with Dolby Atmos and DTS Virtual:X capabilities. While both soundbars deliver rich audio, the LG’s additional channels and features may provide superior clarity and depth, especially for larger entertainment spaces.

Design and Aesthetics

The LG S70TY is designed to complement LG QNED TVs, featuring a sleek crest design and a compact form that allows it to sit neatly beneath the TV or be wall-mounted. This attention to design makes it a stylish addition to any living room. The TCL S45H also boasts a low-profile design that fits well under your TV, providing a modern and premium look. While both soundbars are aesthetically pleasing, the LG's tailored design for its QNED series may appeal more to customers looking for a cohesive setup with their television.

Connectivity Options

The LG S70TY soundbar integrates seamlessly with LG TVs, allowing users to control both the TV and soundbar with a single remote. It is designed for a hassle-free experience, especially when paired with LG's QNED series. On the other hand, the TCL S45H offers extensive connectivity options, including HDMI eARC/ARC, optical, Bluetooth, and AUX, making it compatible with a wide range of devices. This versatility might be more appealing to users with varied entertainment setups, as it allows for easy connection across different devices without the need for multiple remotes.

Features and Functionality

The LG S70TY stands out with its WOW Orchestra feature, which harmonizes audio from the soundbar and LG TV for an enhanced experience. It also includes surround sound expansion capabilities with the option for rear speakers, which can elevate the home theater experience significantly. The TCL S45H, while simpler, includes features like AI Sonic Auto Room Calibration, ensuring optimized audio tailored to your room's layout. Both soundbars have unique functionalities that cater to different user preferences, with the LG offering more advanced options for a fully immersive experience.

Performance in Small Spaces

For smaller rooms or apartments, the TCL S45H is particularly well-suited due to its compact size and powerful 100W output. It delivers room-filling sound without overwhelming smaller spaces, making it an excellent choice for users who want quality audio in limited areas. The LG S70TY, while also capable of delivering powerful sound, is designed for larger setups with its multiple channels, making it potentially more than what is necessary for a smaller environment. Thus, for those in smaller living spaces, the TCL may provide a more practical solution without compromising audio quality.

Brand Reputation and Support

Both LG and TCL are well-recognized in the audio and electronics market. The LG S70TY, with a sales rank of 4,075, reflects a solid presence among consumers, particularly those with LG TVs. TCL, with a better sales rank of 1,824 for the S45H, indicates a growing popularity, especially among users looking for quality at a lower price point. Both brands offer reliable customer support, but TCL has positioned itself as a leader in budget-friendly audio solutions, making it an appealing option for first-time buyers or casual users.

Which should you buy?

The decision between the LG S70TY and TCL S45H ultimately depends on your specific needs and budget. If you are seeking a high-end audio experience and own an LG QNED TV, the LG S70TY offers advanced features and immersive sound that justifies its higher price. However, if you are looking for an economical option that doesn’t compromise significantly on audio quality, the TCL S45H is an excellent choice. With its lower price point and versatile connectivity options, it provides great value for those who want quality sound without breaking the bank.
