Dimension comparison
Design and build quality
The LG S40TR is designed to deliver cinematic sound without occupying excessive space. It features a compact profile intended to fit easily into various room configurations. The system includes a wireless subwoofer, which reduces cable clutter compared to wired alternatives. The ULTIMEA 5.1CH Surround Sound Bar utilizes a 6-driver system including a dedicated wired wooden subwoofer. The wooden enclosure on the subwoofer is often associated with reduced resonance and clearer bass reproduction. While specific dimensions are not provided for either unit, the ULTIMEA model emphasizes a simplified setup that takes less than one minute, suggesting a user-friendly physical design.
Audio channel configuration
Channel configuration determines how sound is distributed around the listening area. The LG S40TR operates on a 4.1 channel system. This includes four main channels backed by a subwoofer. To achieve surround effects, LG includes wireless rear speakers in the package. The ULTIMEA model features a 5.1 channel configuration. It achieves this through five built-in speakers, including two side-firing drivers, paired with a subwoofer. The side-firing drivers are designed to create wide surround sound without the need for physical rear speaker units. This distinction means LG relies on physical separation for surround effects, while ULTIMEA uses driver orientation.
Power and performance
Power output is a critical metric for understanding potential volume and dynamic range. The ULTIMEA sound bar specifies a peak power output of up to 300W. This system uses five precision-tuned full-range drivers to deliver room-filling sound. It also lists a maximum SPL of 99 dB and a frequency response of 45 Hz–18 kHz. These metrics provide concrete data on performance capabilities. In contrast, the LG S40TR product data does not specify wattage or frequency response numbers. It describes the sound as a big audio punch with booming wireless subwoofer support. Without specific numbers, the LG unit's raw power output remains undefined compared to the documented 300W of the competitor.
Subwoofer and bass response
Bass performance relies heavily on the subwoofer design and connection type. The LG S40TR includes a wireless subwoofer. This allows users to place the subwoofer anywhere in the room without running audio cables from the main bar. The ULTIMEA system features a dedicated wired wooden subwoofer. The use of wood in subwoofer construction can enhance structural rigidity, potentially improving bass accuracy. The ULTIMEA unit also highlights BassMX technology powered by an 18 mm high-excursion driver. This suggests a focus on deep low-frequency reproduction. While the LG unit offers placement flexibility, the ULTIMEA unit offers specific technical details regarding its bass drivers.
Surround sound setup
Surround sound implementation differs significantly between the two models. The LG S40TR includes wireless rear speakers. This means the system can create a true surround field with sound coming from behind the listener. The product description notes this is suitable for rooms of all shapes and sizes and requires no special receiver. The ULTIMEA model creates surround sound without rear speakers. It uses side-firing drivers to simulate width and immersion. This simplifies placement as there are fewer components to position around the room. However, physical rear speakers typically offer more precise directional audio than simulated surround sound derived from side-firing drivers.
Smart features and connectivity
Feature sets extend beyond basic audio playback. The LG S40TR supports WOW Orchestra. This feature creates harmony using audio from both the LG TV and the LG Soundbar, provided the user has a compatible LG television. It also supports Dolby Digital and DTS Digital compatibility for enhanced sound quality across shows and movies. The ULTIMEA bar features VoiceMX technology. This uses advanced DSP algorithms to isolate and enhance vocal frequencies in real time. It also boasts Precision DSP ensuring less than 0.5 ms latency for smooth sound. The LG unit focuses on ecosystem integration, while the ULTIMEA unit focuses on signal processing and dialogue clarity.
Price and value
Price is a major factor in the value proposition of these soundbars. The LG S40TR is listed at $196.99. At this price point, it offers wireless rear speakers and brand-specific TV integration. The ULTIMEA 5.1CH Surround Sound Bar is priced at $129.99. This is significantly lower than the LG option. Despite the lower cost, the ULTIMEA model provides higher channel counts (5.1 vs 4.1), documented power output (300W), and Dolby Atmos support. For buyers prioritizing specifications per dollar, the ULTIMEA model presents a stronger value argument. The LG model commands a premium likely due to the inclusion of physical rear speakers and brand ecosystem features.
Which one should you buy?
Choosing between these models depends on specific room needs and budget constraints. If you require physical rear speakers for true surround separation and own an LG TV, the LG S40TR is the logical choice. The wireless rear speakers and WOW Orchestra feature provide benefits that simulated surround cannot match. However, if you prioritize raw power specifications, Dolby Atmos support, and dialogue clarity features like VoiceMX, the ULTIMEA 5.1CH is superior. It also costs less while providing verified performance metrics such as 300W power and 45 Hz–18 kHz frequency response. For most users seeking high performance on a budget, the ULTIMEA option offers more documented capabilities.
