Price Comparison
The LG 55" OLED evo C4 Series TV with the matching S70TY QNED Soundbar is priced at $1,323.94, while the SAMSUNG Q990D 11.1.4ch Soundbar is available for $969.95. This makes the Samsung soundbar about 27% cheaper than the LG set, offering a more budget-friendly option for consumers looking for high-quality audio. Despite the price difference, both products are highly rated, with the LG combination holding a sales rank of 6,447 and the Samsung soundbar being slightly more popular with a rank of 2,912. This price disparity may influence buyers based on their budget and preferences for audio setups.
Audio Performance
The audio performance of the LG soundbar is tailored to complement its OLED TV, featuring a sleek design and advanced technology. It boasts a 3.1.1 channel configuration, which enhances sound quality, especially when paired with the LG TV, while also being compatible with wall mounting. On the other hand, the SAMSUNG Q990D takes audio to another level with its 11.1.4 channel configuration, which includes 11 front-facing speakers, a subwoofer, and four up-firing channels. This setup delivers an immersive Dolby Atmos experience, allowing sound to encapsulate the listener from all directions. The Samsung's inclusion of a rear speaker kit also adds depth to its audio performance, making it superior for those seeking a complete home theater experience.
Design and Aesthetics
The LG soundbar features a modern crest design that is as visually appealing as it is functional, ensuring it fits seamlessly beneath the LG OLED TV or can be wall-mounted. This thoughtful design not only enhances the aesthetic of the entertainment setup but also protects the internal components from dust. In contrast, the SAMSUNG Q990D has a more robust and substantial design, focusing on functionality with built-in smart features and connectivity options. While both soundbars serve their purpose well, the choice may come down to personal taste—whether one prefers the sleek elegance of the LG or the more rugged appearance of the Samsung.
Smart Features
The SAMSUNG Q990D excels in smart features, integrating seamlessly with various smart home devices and voice assistants, including Alexa. It also supports advanced technologies like Q-Symphony, which allows it to work harmoniously with a Samsung TV for enhanced audio performance. Additionally, it includes SpaceFit Sound Pro, which calibrates the audio according to the room's acoustics, providing a tailored listening experience. The LG soundbar, while well-constructed, lacks the same level of smart connectivity and automation, relying more on its audio capabilities and design aesthetics. For tech-savvy users, the Samsung's advanced smart features could be a significant deciding factor.
Setup and Connectivity
Both soundbars offer straightforward setup processes, but there are notable differences in connectivity. The LG soundbar is designed to integrate effortlessly with its matching OLED TV, making it ideal for those who prefer a cohesive LG ecosystem. It is also compatible with the LG QNED Synergy Bracket for wall mounting. The Samsung Q990D, however, stands out with its wireless Dolby Atmos capabilities, which eliminate the need for cumbersome HDMI cables, making it easier to set up in various environments. Additionally, the Samsung offers multiple smart connectivity options, allowing users to connect their devices via Alexa, Chromecast, and AirPlay 2. This flexibility in setup could make the Samsung a more appealing option for users with diverse technology needs.
Surround Sound Experience
When it comes to creating an immersive surround sound experience, the SAMSUNG Q990D truly shines. With its 11.1.4 channel audio configuration, it delivers a rich and enveloping sound that is complemented by its up-firing speakers and included rear speaker kit. This setup is designed to create a multi-dimensional audio landscape, ideal for movie watching and gaming. The LG soundbar, while capable of producing quality audio, does not match the expansive surround sound capabilities of the Samsung system. This disparity in surround sound technology makes the Samsung a stronger contender for those prioritizing a complete home theater experience.
Gaming Features
The Samsung Q990D is particularly well-equipped for gaming, featuring a Game Mode Pro that automatically optimizes audio settings for an enhanced gaming experience. This mode leverages its advanced audio technology to create a 3D sound environment, making it an attractive choice for gamers. The LG soundbar, while providing excellent sound quality, does not specifically highlight gaming features in its offerings. This focus on gaming audio in the Samsung model could be a deciding factor for avid gamers who want the best auditory experience during gameplay.
Which should you buy?
Choosing between the LG 55" OLED evo C4 Series TV with the S70TY QNED Soundbar and the SAMSUNG Q990D 11.1.4ch Soundbar ultimately depends on your specific needs and preferences. If you’re looking for an integrated solution with stunning visuals and decent audio tailored for the LG ecosystem, the LG set might be the right choice. However, if you're after a more immersive audio experience with advanced smart features and a significantly lower price, the Samsung Q990D is hard to beat. Its superior surround sound capabilities and gaming features make it an excellent option for those who prioritize audio and versatility.
