LG S70TY 3.1.1 vs Samsung HW-B750F
Quick Verdict
For LG TV owners, especially QNED owners, the LG S70TY 3.1.1 is the better choice because it includes Dolby Atmos and DTS:X, an up-firing center channel for dialogue, and rear speaker expandability with WOW Orchestra and WOW Interface integration. For Samsung TV owners who prefer a 5.1 channel layout with side firing drivers and DTS Virtual:X, the Samsung HW-B750F is a solid lower mid-range option. Both lack published power, driver sizes, HDMI eARC, dimensions, and streaming details, so neither can be fully assessed on specs alone. Choose the LG for object based audio and future growth. Choose the Samsung for virtual surround and Q-Symphony on a Samsung TV.

Sound Quality
Published sound quality scores are close: the LG S70TY earned 24 out of 30 and the Samsung HW-B750F earned 23 out of 30. The LG uses a 3.1.1 channel configuration with an up-firing center channel that specifically aims dialogue upward for clarity. The Samsung offers a 5.1 channel layout with five front and side firing channels plus a wireless subwoofer, which should create a wider front soundstage. Both listings leave wattage and driver sizes unpublished, so absolute output and driver quality cannot be directly compared.
The LG's listed pros point to a tuned match with LG QNED TVs, while the Samsung's side firing drivers are intended to broaden stereo separation. Neither listing supplies frequency response or total power, so tonal balance and headroom remain unclear. The LG emphasizes dialogue clarity through its up-firing center, while the Samsung includes Voice Enhance Mode and Adaptive Sound described to target dialogue.
For pure channel count, the Samsung's 5.1 has more discrete front and side channels than the LG's 3.1.1, but the LG includes an up-firing element that the Samsung does not mention. Both are lower mid-range options and their sound quality scores indicate similar overall performance expectations. Without published specifications, buyers should weigh integration and format support rather than raw acoustic data.
Surround, Atmos and Audio Formats
The LG S70TY supports Dolby Atmos and DTS:X, which are object based formats that can deliver height effects. The Samsung HW-B750F supports Dolby Audio 5.1 and DTS Virtual:X, but the listing does not list Dolby Atmos. The LG's Atmos and DTS:X support gives it an advantage for modern streaming and Blu-ray soundtracks that carry height metadata.
The Samsung relies on DTS Virtual:X to create a virtual surround effect from its 5.1 channel layout without rear speakers. The LG's 3.1.1 configuration includes an up-firing center but no physical side or rear channels in the base package; it is rear speaker ready, which means you can add compatible rear speakers later. The Samsung does not mention rear speaker expansion.
For buyers who want native object based audio now, the LG is the only model with Atmos and DTS:X. For buyers who prefer a wider virtual surround stage from built-in side channels, the Samsung's DTS Virtual:X and five channel arrangement may be more appealing. Both models trail discrete surround packages because neither ships with rear speakers. The LG's future expandability may offset that limitation for some.
Subwoofer and Bass
Both models include a wireless subwoofer, which simplifies placement and reduces cable clutter. The LG lists a wireless subwoofer included but does not publish driver size, amplifier power, or bass tuning details. The Samsung also includes a wireless subwoofer but likewise does not publish driver size or amplifier power. This makes direct bass comparison impossible from the listing facts.
The Samsung's pros mention 'wireless subwoofer included for flexible placement' and its cons note no detailed bass controls or subwoofer specs. The LG's pros do not mention specific subwoofer performance, only that the system includes one. Neither listing states frequency range or cabinet design, so extension and impact cannot be assessed.
A practical difference is that the LG's 3.1.1 setup includes one subwoofer plus an up-firing center, while Samsung positions its subwoofer as part of a 5.1 channel system that already has side drivers. The absence of published subwoofer specs means buyers cannot verify low frequency extension or output for either model. Without these numbers, the decision on bass should not rest on subwoofer specs; it should follow the overall channel and format needs.
Connectivity and TV Setup
The LG listing states it includes 4K, Dolby Vision, HDR10 and 120Hz passthrough, but does not publish HDMI eARC and input details. That matters for high bandwidth video signals and for simplified TV audio return. The Samsung HW-B750F does not publish HDMI eARC or input details either. Both models therefore leave a key connectivity question unanswered.
The LG can be controlled via an LG TV remote with WOW Interface, and WOW Orchestra integration is listed for compatible LG TVs. The Samsung does not publish remote or app details, but Q-Symphony is listed to work with compatible Samsung TVs. This means TV brand compatibility is an important setup consideration for both.
For physical inputs, neither listing confirms the number or type of HDMI ports, optical, or auxiliary connections. Buyers should check product documentation or return policies before purchase if they need a specific connection. In this comparison, the LG has an edge for confirmed video passthrough features, but the Samsung's connectivity is largely unspecified.
Features, Apps and Voice Control
The LG lists WOW Orchestra and WOW Interface, which allow compatible LG TVs to use the TV remote and combine TV speakers with the soundbar. No dedicated remote or app is mentioned in the listing. Bluetooth and Wi-Fi streaming specifications are not published. This means general music streaming and smart assistant integration are not confirmed.
The Samsung HW-B750F also does not publish streaming and app support beyond the wireless subwoofer connection. The listing does not mention a remote or app, but it describes Voice Enhance Mode and Adaptive Sound modes. Q-Symphony is listed for compatible Samsung TVs, allowing the TV speakers and soundbar to work together.
Voice control is not explicitly listed for either model. The LG's WOW Interface can provide TV remote control integration, but that is not the same as a voice assistant. Samsung's Voice Enhance is a dialogue mode, not a voice control feature. Buyers seeking built-in Alexa, Google Assistant, or Apple AirPlay should confirm support separately because the listings do not state it.
Design and Fit Under a TV
The LG is described as compact and made to match LG QNED TVs. Its dimensions are not published in the listing, so exact height, width, and depth cannot be checked for fit under a specific TV. The Samsung also does not publish dimensions, so both soundbars require measurement verification before purchase.
The LG's compact design and QNED matching suggest a low profile that should fit under many wall mounted or stand mounted LG TVs. The Samsung's design is not described in the listing beyond the channel configuration and wireless subwoofer. Neither model includes wall mounting hardware details in the listing.
A practical difference is that the LG includes an up-firing center channel, which may add height or require clearance to reflect sound off a ceiling. The Samsung has side firing drivers that need open space on the left and right for the virtual surround effect. Both factors mean the physical placement around the TV and room should be considered, even though exact dimensions are not published.
Who Should Buy It
The LG S70TY is best for LG TV owners, especially QNED owners, who want a compact Atmos soundbar with simple integration and rear speaker expandability. Its WOW Orchestra, WOW Interface, and TV remote control make setup easier if you already have a compatible LG TV. It is also suitable for buyers who need Dolby Atmos and DTS:X in a lower mid-range package.
The Samsung HW-B750F is best for buyers who want a lower mid-range 5.1 channel Samsung soundbar with a wireless subwoofer and virtual surround for TV, movies, and gaming. It appeals to Samsung TV owners who can use Q-Symphony and to those who prefer built-in side firing channels over an up-firing center.
Both are aimed at buyers who do not need fully published specs or discrete rear speakers out of the box. The LG favors integration and object based audio, while the Samsung favors channel count and virtual surround. Buyers who need documented power, driver sizes, dimensions, connectivity, or streaming should avoid both until those details are confirmed.
The Deciding Question
The deciding question is whether you need Dolby Atmos and DTS:X, or whether a virtual surround 5.1 layout is enough. The LG S70TY supports Atmos and DTS:X and adds an up-firing center channel, while the Samsung HW-B750F does not list Atmos and instead uses DTS Virtual:X with side firing drivers.
If your priority is object based height effects and future rear speaker expansion, the LG is the more fitting choice. If your priority is a wider front and side soundstage from a single bar and you own a compatible Samsung TV, the Samsung may serve you better.
The second deciding factor is TV brand ecosystem. LG's WOW features and QNED matching only work fully with compatible LG TVs. Samsung's Q-Symphony works with compatible Samsung TVs. If you do not own a compatible TV from either brand, the integration advantages diminish and you should compare other specifics such as format support and channel layout.
Who Should Buy Which
Choose the LG S70TY if you own a compatible LG TV, especially a QNED model, and want Dolby Atmos, DTS:X, an up-firing center for dialogue, and the ability to add rear speakers later. Its compact design and WOW Orchestra integration are practical benefits that are not available on the Samsung.
Choose the Samsung HW-B750F if you own a compatible Samsung TV and prefer a 5.1 channel layout with side firing drivers and DTS Virtual:X over Dolby Atmos. Its Voice Enhance and Adaptive Sound modes target dialogue without requiring an up-firing center, and Q-Symphony ties it into your Samsung TV's speakers.
If you do not own a compatible TV from either brand, the LG's Atmos and DTS:X support and rear speaker readiness give it a broader appeal, while the Samsung's virtual surround and 5.1 channel count may be enough for general TV and movie use. However, both models leave many specs unpublished, so verify connectivity and physical dimensions before deciding.
