LG S60T.CUSALLK Review: 3.1 Channel Soundbar with AI Sound Pro

For those seeking to upgrade their home audio without the complexity of a full surround system, the LG S60T.CUSALLK soundbar presents a streamlined solution. This 3.1-channel audio system combines a soundbar with a wireless subwoofer, aiming to deliver cinematic sound with minimal cable clutter. The bottom line up front: this soundbar excels in delivering clear dialogue and room-filling bass with AI-driven optimization, but its full feature set is best unlocked for users within the LG ecosystem.
The core appeal of the LG S60T.CUSALLK lies in its simplified 3.1-channel configuration—left, right, center, and a wireless subwoofer—designed to provide a significant audio upgrade over standard TV speakers. Its built-in AI Sound Pro technology and support for Dolby Audio promise an immersive experience for movies, sports, and music. However, potential buyers should note that key features like WOW Orchestra and WOW Interface are exclusive to use with compatible LG televisions, which may influence its value proposition depending on your existing setup.

Design and Build
The LG S60T.CUSALLK features what LG calls its “Crest Design,” which gives the soundbar a distinct, sleek profile. The unit is constructed with a metal grill that serves a dual purpose: it contributes to the soundbar’s modern aesthetic while also functioning to keep dust and debris away from the internal speakers. At 33.5 inches wide, it is designed to fit neatly below many modern televisions. The soundbar is also wall-mountable, as indicated by its listed mounting type, and the manufacturer includes a wall mount bracket in the package.
The wireless subwoofer, with dimensions of 7.9″W x 14.8″H x 11.2″D, allows for flexible placement in a room to optimize bass response without the constraint of a physical cable connection to the main unit. The overall build quality, as suggested by the enclosure material listed as metal for the soundbar grill, points towards a durable construction intended for long-term home use.
Performance and Features
Audio Performance
The defining characteristic of the LG S60T is its 3.1-channel configuration. The dedicated center channel is specifically engineered to enhance vocal and dialogue clarity, a common weak point in basic audio systems. This makes it well-suited for movies, TV shows, and live sports where understanding speech is crucial. The wireless subwoofer is tasked with delivering the low-frequency effects, providing the rumble and impact for a more cinematic experience. The soundbar supports Dolby Audio technologies, which work to create a more immersive, spatial soundscape from compatible content.
A key performance feature is AI Sound Pro. According to the manufacturer, this technology uses deep learning algorithms to automatically analyze the audio content and adjust sound settings accordingly. It is designed to enhance vocals in sports broadcasts, boost bass for music, and optimize dynamics for action scenes, all without manual user intervention.
Connectivity and Compatibility
Primary connections include HDMI with eARC (Enhanced Audio Return Channel), which allows for high-quality audio transmission from a compatible TV, and Bluetooth for wireless streaming from smartphones or other devices. The specifications list wireless technology as Wi-Fi, though its specific function (e.g., for music streaming services) is not detailed by the manufacturer. An optical audio input is also included, as noted by the optical cable in the package contents. It is important to highlight that the product specifications show it does not support HDMI 4K pass-through, meaning it cannot act as a video switch for 4K sources.
The most notable compatibility aspects are its integration features with LG televisions. The WOW Orchestra feature is designed to use the speakers of both a compatible LG TV and the LG soundbar in harmony to create a wider, more detailed soundstage. The WOW Interface allows control of both the soundbar and LG TV with a single TV remote, displaying settings on the TV screen. The manufacturer explicitly notes these features are only available on select LG TV and LG soundbar models.
Software and Control
Beyond the included remote control, the LG S60T can be managed via the LG Soundbar App. This app enables users to customize audio settings, including adjusting a 3-band equalizer. The app also provides control for any connected rear speakers, though the S60T itself is a 3.1 system and does not include rear speakers. The control protocol is listed as Bluetooth.
Setup, Support and Ownership
Setup appears straightforward, leveraging wireless connections for the subwoofer and offering multiple audio input options. The package includes the necessary cables (optical) and hardware (wall mount bracket) to get started. The product is compatible with home theater systems, televisions, and smartphones. For users looking to expand the system, the LG Soundbar App mentions functionality for rear speakers, indicating the soundbar may support an optional wired or wireless rear speaker kit, though specifics are not provided in the available data.
LG offers a standard limited warranty of 1 year for parts and labor. The manufacturer also notes an EU spare part availability duration of 7 years, which may be relevant for long-term repairability in supported regions. As a mainstream electronics brand, LG typically provides support through online resources, manuals, and customer service channels.

As no detailed buyer review excerpts are available, this aggregate score suggests early adopters are generally satisfied with the product’s performance.

Who Should Buy It (and Who Should Skip It)
The LG S60T.CUSALLK is an ideal choice for users with compatible LG televisions who want a significant, one-box audio upgrade with minimal setup. It’s particularly well-suited for those who prioritize clear dialogue in movies and TV shows and appreciate the convenience of AI-driven sound optimization. The wireless subwoofer makes it a good fit for living rooms where hiding cables is a priority. For more options in home entertainment tech, browse our Tech Gear category.
This soundbar is less suitable for users who do not own an LG TV, as they will miss out on its signature integration features. Those requiring true surround sound with rear speakers from the outset should look for a system that includes them. Similarly, home theater enthusiasts who need a soundbar with 4K video pass-through to act as a media hub should consider other models. If you’re evaluating different types of home tech, our Reviews page offers a wide range of comparisons.
Final Verdict
The LG S60T.CUSALLK soundbar effectively fulfills its mission of delivering a substantial audio upgrade over built-in TV speakers. Its strengths are clear: excellent dialogue reproduction thanks to the dedicated center channel, powerful and convenient wireless bass, and smart sound tuning via AI Sound Pro. The design is both attractive and practical. When paired with a compatible LG television, its value increases significantly through seamless integration features that create a unified and user-friendly home entertainment experience.
However, its appeal is undoubtedly narrowed by its brand-specific optimizations. The absence of HDMI 4K pass-through and the lack of included rear speakers are compromises that buyers must weigh. Ultimately, this soundbar shines brightest as a tailored upgrade for the LG ecosystem. Outside of that, it remains a competent 3.1 system, but faces stiff competition from more universally compatible options in the market.
FAQs
Does the LG S60T support Dolby Atmos?
No, the product specifications and features list support for Dolby Audio, but do not mention Dolby Atmos. The 3.1-channel configuration, without upward-firing or rear speakers, is not designed for the object-based, overhead sound experience that Dolby Atmos provides.
Can I add rear speakers to the LG S60T soundbar?
The LG Soundbar App mentions functionality for customizing settings for rear speakers, which strongly suggests the system can be expanded. However, the specific model numbers of compatible rear speakers, whether they are wired or wireless, and their cost are not detailed in the manufacturer-provided data.
What is the difference between WOW Orchestra and AI Sound Pro?
WOW Orchestra is an integration feature that combines the audio output of compatible LG TVs and LG soundbars for a more expansive soundstage. AI Sound Pro is an audio processing technology within the soundbar itself that analyzes content (sports, music, movies) and automatically adjusts EQ and dynamics to optimize the listening experience for that specific type of content.
Can I use the soundbar with a non-LG TV?
Yes, you can connect the LG S60T to any television with an HDMI-ARC/eARC port, an optical audio output, or via Bluetooth. You will have full access to its core audio features like the 3.1-channel sound, Dolby Audio, AI Sound Pro, and the wireless subwoofer. However, the WOW Orchestra and WOW Interface features will not be available, as they require specific integration with an LG television.
