The team at Senses has evaluated the LG SC9S soundbar, and we found it delivers performance commensurate with its price point, and in some areas, exceeds expectations. One of the most frustrating aspects of new technology is a steep learning curve. Fortunately, this was not the case with the SC9S. Setup proved remarkably straightforward, negating the need for extensive manual consultation. Connecting the soundbar involved simply plugging it in with a power cable and an HDMI 2.1 cable to the TV, along with a power cable for the subwoofer. The entire process was remarkably smooth and efficient, allowing us to proceed directly to testing.
The wireless subwoofer design is a notable advantage, requiring only a power cable. Utilizing both Wi-Fi and Bluetooth 5.2, the subwoofer can be positioned freely within the room without cable constraints. The integrated Wi-Fi also facilitates firmware updates and music streaming via Alexa or Google Home. While the system is expandable with optional surround speakers, this addition can significantly increase the overall cost. Note that enabling surround sound configures the system in a 5.1 arrangement which may affect the overall sound quality depending on content source. However, the SC9S soundbar performs admirably for a wide range of audio applications.
The soundbar features a premium design, incorporating metal accents for a refined aesthetic. Its dimensions (63 mm high and 975 mm wide) make it a suitable fit beneath most televisions. Specifically, it proved unobtrusive when placed under a 58-inch display, a benefit for users who have not wall-mounted their TVs. It is worth noting that LG recommends pairing this soundbar with an OLED TV from their C-series to take advantage of the “Wow bracket” mounting system. This bracket offers a seamless and stylish integration when the TV is wall-mounted. While we tested the soundbar independently of this bracket, the experience was still positive.
Control of the soundbar is facilitated via the included remote, the LG companion app, or through integration with Alexa or Google Home devices. Voice commands such as “Alexa, play some music” are supported. Physical controls are also present on the soundbar itself, providing seven distinct buttons for direct operation. Audio playback was tested using Spotify, with the subwoofer delivering a satisfying presence across various music genres.
We also evaluated the soundbar’s performance with gaming and movies, specifically testing The Last of Us on Playstation 5 and the movie Top Gun Maverick. While gaming audio was a marked improvement over the built-in TV speakers, the cinematic experience proved particularly compelling, offering enhanced clarity and depth.
The SC9S supports a wide range of audio formats, including Dolby Atmos, Dolby True HD, DTS:X, and DTS-HD. The system incorporates nine speakers: four front-facing, three upward-firing, and two rear-firing. Connectivity options include two HDMI 2.1 ports, a USB port, and a DC power port. The front of the soundbar features three LED indicators that provide visual feedback on volume level and other settings. Multiple sound modes are available, catering to different listening scenarios. While a graphic equalizer would offer more granular control over the sound profile, the inclusion of a room correction tool, which automatically optimizes audio output for the specific environment, is a valuable and relatively uncommon feature.
