Samsung S800D 3.1.2ch vs TCL Q85H 7.1.4
Quick Verdict
The Samsung S800D 3.1.2ch is the better choice for Samsung TV owners who want a slim, voice controlled soundbar with built in Chromecast, AirPlay 2, and automatic room tuning. It offers Dolby Atmos through up firing channels and a wireless subwoofer, but the listing omits power, HDMI details, and dimensions. The TCL Q85H 7.1.4 is the better choice for movie lovers who want a full 7.1.4 layout with dedicated rear speakers, DTS:X decoding, and a published 860 watts. It lacks Wi-Fi streaming and voice assistants, but it provides a more traditional surround experience. Choose Samsung for smart features and design, TCL for immersive surround and power.

Sound Quality
The Samsung S800D 3.1.2ch earns a sound quality score of 24 out of 30, while the TCL Q85H 7.1.4 earns 23 out of 30. Both scores suggest strong mid-range performance, but the listings reveal very different physical designs. Samsung describes a 3.1.2ch configuration with up firing channels, which means it includes a center channel, a left and right pair, one subwoofer, and two height channels driven toward the ceiling. TCL describes a 7.1.4 configuration with seven main channels, one subwoofer, and four height channels, which typically includes dedicated rear speakers. This channel difference does not automatically mean one sounds better, but it does indicate how each model approaches immersion.
Samsung does not publish driver sizes, amplifier power, or frequency response in the listing, so objective sound quality beyond the channel count is hard to verify. The listing does highlight sound tuning features such as SpaceFit Sound Pro automatic room calibration, Adaptive Sound, and AVA for dialogue clarity. These features can adjust output to the room and boost speech, which may benefit mixed content like news or dramas. However, without published power or driver details, buyers cannot compare raw output capability to other systems.
TCL publishes a total power figure of 860 watts, which is a concrete number the Samsung listing does not provide. The TCL listing also mentions AI Sonic room tuning via the TCL app, but it does not publish driver sizes or frequency response. The higher channel count and 860 watts suggest the TCL may fill a larger room more easily, but the lack of driver details leaves some uncertainty. In practice, both units likely perform well for typical living rooms, but the TCL has a stronger on paper foundation for dynamic range.
Surround, Atmos and Audio Formats
Samsung supports Dolby Atmos and uses up firing channels to create height effects. The listing does not state DTS support, so buyers who rely on DTS encoded Blu ray discs or streaming content with DTS may not get native decoding. The Samsung configuration is 3.1.2, which provides a front heavy surround field with height but no dedicated rear speakers. For a soundbar only setup, that can still produce a noticeable Atmos effect, but it is not a true 5.1 or 7.1 physical surround layout.
TCL supports both Dolby Atmos and DTS:X, which is a meaningful advantage for disc collectors and some streaming services that use DTS. The 7.1.4 channel layout includes dedicated rear speakers, and the listing states those rear speakers include front and up firing drivers. That means the TCL can create actual rear surround effects and four height channels, two from the bar and two from the rear speakers. This is a more traditional home theater setup with separate rear channels.
Neither listing mentions support for other formats like DTS:X Pro, IMAX Enhanced, or Auro 3D, so both are limited to mainstream codecs. Samsung lists no audio format beyond Dolby Atmos, while TCL lists both Atmos and DTS:X. If your media library is primarily Dolby Atmos and Dolby Digital, both will work. If you need DTS decoding, the Samsung listing does not confirm it, making the TCL the safer choice.
Subwoofer and Bass
Both systems include a wireless subwoofer, which is convenient for placement without a cable run to the soundbar. Samsung does not publish the subwoofer size, driver diameter, or amplifier power. The listing only confirms a wireless subwoofer is included. TCL also includes a wireless subwoofer, and its total system power is listed at 860 watts, but the listing does not break out how much of that goes to the subwoofer versus the bar and rear speakers.
The Samsung listing emphasizes a slim profile but does not describe bass performance, so buyers cannot infer low frequency extension from the published information. The wireless design allows you to place the subwoofer in a corner or near a wall to reinforce bass, but without a size rating we cannot compare to typical 6 inch or 8 inch drivers. TCL's higher total power and larger channel count may suggest a more capable subwoofer, but that is an inference not stated by the listing.
For buyers who care about deep bass for movies, the TCL has an advantage on paper because of the 860 watt figure and the inclusion of rear speakers that often carry bass information in a 7.1.4 mix. Samsung may still produce tight bass for music and dialogue, but the lack of published power numbers makes direct comparison difficult. If subwoofer output is critical, you would need to audition both or wait for more detailed specs from the manufacturer.
Connectivity and TV Setup
Samsung's listing does not publish HDMI eARC or input details, which is a notable omission for a modern soundbar. The listing does confirm Wi-Fi streaming support with built in Alexa, Chromecast, and AirPlay 2, so you can connect wirelessly for music and multi room audio. Bluetooth is not explicitly stated, so buyers who want direct Bluetooth streaming should confirm before purchase.
TCL lists HDMI eARC/ARC and an optical input, but it does not specify the number of HDMI inputs. It includes Bluetooth for music streaming, but the listing does not mention Wi-Fi, AirPlay, or Chromecast. This means TCL owners will likely connect a TV via HDMI eARC for all audio, and use Bluetooth for phone or tablet streaming, but they cannot use the soundbar as a Wi-Fi speaker outside of Bluetooth range.
Samsung's Q Symphony feature is a TV setup differentiator for owners of compatible Samsung TVs. Q Symphony lets the soundbar work in tandem with the TV speakers to create a wider soundstage, though we cannot verify the exact behavior without in-person testing. TCL has no equivalent TV integration feature listed. For simple TV connection, both use HDMI eARC or optical, but Samsung's missing HDMI details make it harder to plan for multiple source devices.
Features, Apps and Voice Control
Samsung includes built in Alexa, Chromecast, and AirPlay 2, which means you can ask Alexa to play music, control smart home devices, or cast audio from apps. The listing also mentions SpaceFit Sound Pro, Adaptive Sound, and AVA, which are automatic sound modes that adjust based on content and room. These features add convenience for users who want a set and forget system with voice control.
TCL includes AI Sonic room tuning via the TCL app, which likely serves a similar purpose to Samsung's SpaceFit Sound Pro by measuring the room and adjusting EQ. The TCL listing does not mention any built in voice assistant, so you cannot issue voice commands directly to the soundbar. It does include a remote control and app control for manual adjustments. TCL's app may offer more granular control than the Samsung, but the listing is light on specifics.
Samsung's integration of Chromecast and AirPlay 2 means it can be part of a whole home audio setup with other compatible speakers. TCL's Bluetooth only streaming is more limited for multi room use. If voice control and smart home integration are priorities, Samsung is the clear choice based on the listings. If you prefer using a physical remote or the TCL app and do not need voice, TCL still covers basic adjustments and room tuning.
Design and Fit Under a TV
Samsung highlights an ultra slim low profile design, which suggests it is intended to sit discreetly under a TV without blocking the screen. The listing does not publish dimensions, so you cannot verify exact height or width for your furniture. That omission is significant for buyers with a tight TV stand or a TV mounted low on the wall.
TCL also does not publish dimensions or weight, which makes physical fit harder to plan. The TCL system includes a main soundbar, a wireless subwoofer, and two rear speakers, so you need space for all components. The listing does not describe the bar's height or the rear speaker size, so confirm measurements before ordering if space is limited.
Samsung's slim design is a differentiator for buyers who want a minimal footprint. TCL's design is not described as slim, and the presence of rear speakers means it is a more traditional home theater package. If you are placing the soundbar on a console between TV legs, Samsung's low profile is likely easier to accommodate, but without published dimensions that remains an assumption based on the marketing language.
Who Should Buy It
Samsung S800D 3.1.2ch is best for Samsung TV owners who want a slim Atmos soundbar with a wireless subwoofer and automatic room tuning. The built in Alexa, Chromecast, and AirPlay 2 make it a strong fit for households that stream music and use voice assistants. Buyers who value a low profile design over maximum channel count will appreciate this model.
TCL Q85H 7.1.4 is best for buyers who want a mid range Dolby Atmos system with dedicated wireless rear speakers and a subwoofer for immersive movie watching. The inclusion of DTS:X and the published 860 watt total power make it appealing for home theater enthusiasts on a budget. It is also a good choice for buyers who do not need Wi-Fi streaming or voice assistant support.
Both models are aimed at buyers who want an upgrade from TV speakers without investing in a full AV receiver and wired speakers. Samsung trades channel count and rear speakers for slim design and smart features. TCL trades smart streaming and voice for a more complete surround layout and higher power. Your priorities will determine which is a better fit.
The Deciding Question
The fundamental question is whether you value a slim, smart soundbar with built in streaming and voice, or a full 7.1.4 surround system with dedicated rear speakers and DTS:X. Samsung's 3.1.2 configuration is more self contained and elegant but cannot match the physical rear channel separation of TCL's dedicated rear speakers. If your room can accommodate rear speakers, TCL will likely provide a more convincing surround bubble.
Another deciding factor is compatibility with your TV brand. Samsung's Q Symphony only works with compatible Samsung TVs, so if you own one, Samsung has a strong integration advantage. TCL does not require a specific TV brand, but it also lacks a TV speaker sync feature. For non Samsung TV owners, TCL's standard HDMI eARC connection is straightforward and brand agnostic.
Finally, consider the unknown specifications. Samsung omits HDMI details, power, and dimensions, while TCL omits driver sizes, dimensions, and HDMI input count. If you need to verify exact fit or input capacity before buying, both listings leave gaps. The Samsung listing is more incomplete on power and HDMI, while TCL at least publishes total power and confirms eARC/ARC and optical.
Who Should Buy Which
Buy the Samsung S800D 3.1.2ch if you own a compatible Samsung TV and want to use Q Symphony, if you want a slim soundbar that sits low under the screen, or if you rely on built in Alexa, Chromecast, and AirPlay 2 for wireless streaming. Also choose Samsung if you want SpaceFit Sound Pro and AVA for automatic dialogue enhancement without manual tweaking.
Buy the TCL Q85H 7.1.4 if you want a true 7.1.4 channel layout with dedicated rear speakers and up firing drivers for overhead effects, if you need DTS:X decoding for your disc or streaming library, or if you have a larger room and value the published 860 watt total power. Also choose TCL if you are okay with Bluetooth only streaming and no built in voice assistant.
If you are still uncertain, focus on the physical space. Samsung's soundbar plus subwoofer has a smaller footprint, while TCL adds two rear speakers that require placement behind or beside the seating area. Both are mid range Atmos systems with wireless subwoofers and automatic room tuning, but they serve different room layouts and user preferences.
