LG S70TY 3.1.1-Channel QNED TV Matching Soundbar, Dolby Atmos, Wow Orchestra, Rear Speaker Ready, Wireless Subwoofer vs ULTIMEA 5.1CH Surround Sound Bar with Subwoofer, Dolby Atmos, VoiceMX, BassMX, APP, 300W Soundbar for Smart TV, Home Theater Surround Sound System for TV, BT 5.4, Poseidon M60 (2025 Model)

Price and Value Comparison

The ULTIMEA 5.1CH Surround Sound Bar is significantly more affordable than the LG S70TY, priced at $129.99 compared to $346.99—about 63% cheaper. This price difference reflects a fundamental divergence in positioning: ULTIMEA targets budget-conscious buyers seeking immersive audio without premium branding, while LG positions the S70TY as a high-end, TV-integrated audio solution. Despite the lower cost, ULTIMEA maintains strong technical credentials with a 300W output and Dolby Atmos support. The LG model’s higher price is justified by its integration with LG QNED TVs and exclusive features like WOW Orchestra and a wireless subwoofer, but for users not invested in the LG ecosystem, ULTIMEA offers far greater value per dollar.

Audio Technology and Immersion

The LG S70TY delivers a unique up-firing center channel designed specifically for dialogue clarity, enhancing vocal presence in Dolby Atmos content. It supports 3.1.1-channel audio with an industry-exclusive up-firing center driver, creating a spatial soundstage that fills larger rooms. ULTIMEA matches this with its own 5.1-channel setup using five built-in speakers, including side-firing drivers, which generate wide surround sound without requiring rear speakers. Both systems support Dolby Atmos, but ULTIMEA emphasizes real-time precision DSP with less than 0.5 ms latency for seamless audio synchronization. While LG focuses on synergy with its TV lineup, ULTIMEA prioritizes consistent, theater-like immersion through advanced signal processing and a 300W peak output.

Speaker Configuration and Setup

The LG S70TY uses a 3.1.1-channel layout with a wireless subwoofer and rear speaker readiness, allowing for future expansion via two wireless rear speakers. Its design is optimized for placement beneath LG QNED TVs, with dimensions that allow it to nest neatly on a stand. ULTIMEA, in contrast, uses a fixed 5.1-channel configuration with five built-in drivers and a dedicated wired wooden subwoofer. It requires no additional rear speakers, delivering full surround sound out of the box. ULTIMEA claims setup takes less than one minute, leveraging HDMI eARC and CEC integration for automatic device pairing. The LG system, while offering more flexibility through expandability, demands more planning due to its reliance on compatible accessories and bracket support.

Voice Clarity and Sound Processing

ULTIMEA stands out with VoiceMX technology, which uses advanced DSP algorithms to isolate and enhance vocal frequencies in real time. This ensures dialogue remains clear even during loud action sequences or low-volume playback. The LG S70TY does not mention a similar feature, relying instead on its up-firing center channel to improve speech intelligibility. However, LG’s WOW Interface allows unified control via the TV remote, enabling quick adjustments to audio settings directly from the screen. ULTIMEA’s app-based control offers deeper customization, including a 10-band graphic EQ and 121 sound presets, giving users granular control over their listening experience. For audiophiles who want fine-tuned tuning, ULTIMEA’s app provides more options than LG’s integrated interface.

Subwoofer Performance and Bass Quality

The ULTIMEA subwoofer is a wired, wooden cabinet with an 18 mm high-excursion driver and a 5.3L tuned enclosure, powered by BassMX technology to deliver deeper, tighter bass with enhanced air displacement. This design aims to reproduce cinematic low-frequency effects with realism. The LG S70TY includes a wireless subwoofer, which offers greater placement flexibility but lacks details on driver size or cabinet construction. ULTIMEA’s system achieves a maximum SPL of 99 dB, indicating powerful output capable of filling large rooms. While both systems support deep bass, ULTIMEA’s focus on physical driver engineering and cabinet tuning suggests a more robust low-end performance, especially for action films and music with heavy bass.

Connectivity and Smart Features

Both soundbars support HDMI eARC for high-bandwidth audio transmission, unlocking full Dolby Atmos 5.1-channel capabilities. ULTIMEA adds Bluetooth 5.4, which offers faster syncing and more stable connections than previous versions. The LG S70TY relies on standard Bluetooth functionality, though specific version details are not provided. ULTIMEA’s app enables OTA updates, ensuring long-term compatibility and feature improvements. The LG S70TY integrates seamlessly with LG TVs through the WOW Interface, allowing single-remote control of both devices. ULTIMEA’s app also supports 13 adjustable surround levels, letting users tailor audio to room acoustics. For smart home integration, ULTIMEA’s app-driven approach gives it an edge in customization and future-proofing.

Which should you buy?

Choose the ULTIMEA 5.1CH Surround Sound Bar if you want a powerful, immersive audio system at a fraction of the cost—$129.99 versus $346.99—without sacrificing core features like Dolby Atmos, 300W output, or voice clarity enhancement. Its 5.1-channel setup with built-in surround drivers and a wired subwoofer delivers theater-quality sound right out of the box, and its Bluetooth 5.4 and app control offer modern connectivity and customization. However, if you own an LG QNED TV and prioritize seamless integration, the LG S70TY offers unmatched synergy with its TV, wireless subwoofer, rear speaker readiness, and up-firing center channel for superior dialogue clarity. The S70TY is best suited for LG ecosystem users willing to pay a premium for a cohesive, stylish audio-visual experience.
