Best Soundbars with 4K Pass-Through for 2026: a Buyer’s Guide

The TCL S65K is a complete 5.1 channel home theater audio system designed for viewers who want a genuine surround sound experience without the complexity of a traditional AV receiver setup. It includes the main soundbar, a wireless subwoofer, and wireless rear surround speakers, making it ideal for living rooms and dedicated home theater spaces where immersive audio is a priority.

The headline features are Dolby Atmos and DTS:X support, which provide spatial audio that creates the sensation of sound coming from above and around you. Combined with TCL's proprietary Ray Danz Technology, the soundstage extends well beyond the physical footprint of the speakers, lending a convincing sense of depth and dimension to movies and games.

Setup is refreshingly simple thanks to a single HDMI connection, and the AI Sonic Auto Room Calibration feature intelligently measures your space and adjusts the audio profile accordingly. The 6.5-inch wireless subwoofer with Bass Boost adds genuine low-frequency impact, while the built-in center channel tweeter ensures dialogue remains clear even during loud action sequences. ChoruSound integration with your TV's existing speakers further widens the perceived soundstage.

On the downside, the system's size and the need to position rear speakers means it demands more room planning than a compact soundbar. Users in smaller apartments may find the full 5.1 configuration a tight fit, and those unfamiliar with audio technology may need some time to explore all the settings and connectivity options including Bluetooth, USB, and Wi-Fi.

Overall, the TCL S65K delivers exceptional value for a fully wireless 5.1 surround system with premium audio codec support. It is a strong recommendation for anyone looking to upgrade their home theater audio significantly without spending on a high-end separates system. The combination of smart calibration, powerful output, and easy setup makes it one of the more compelling all-in-one audio solutions available at this price point.

If you are considering the TCL S65K, it helps to know what sets a 5.1 system apart from a standard soundbar. A 5.1 setup includes a center channel, two front channels, two surround channels, and a subwoofer, delivering true positional audio rather than simulated surround. The S65K achieves this with physical wireless rear speakers, which is a meaningful advantage over soundbars that rely solely on virtual surround processing.

This system is best suited for rooms where you can place the rear speakers a few feet behind or beside your primary seating position. A rectangular living room or a dedicated home theater room will get the most benefit from the full 5.1 configuration. For very small rooms or open-plan spaces, the audio may feel overwhelming at higher volumes, so consider your room size before purchasing.

Dolby Atmos and DTS:X are worth having if you subscribe to streaming services like Netflix, Disney Plus, or Apple TV Plus, as a growing library of content is mixed in these formats. You will need a TV or media player that passes through these audio signals via HDMI ARC or eARC to take full advantage of them. Confirm your TV's HDMI port supports ARC or eARC for the best experience.

Compared to competing 5.1 systems at a similar price, the inclusion of AI room calibration and Ray Danz Technology gives the S65K a measurable edge in audio tuning and soundstage width. If your priority is convenience, immersive audio, and a clean wireless setup, the TCL S65K is a well-rounded choice that punches above its price class.

The Samsung HW-B630F is a 3.1 channel soundbar system designed for everyday home theater enthusiasts who want better dialogue clarity and immersive sound without the complexity of a full surround setup. It combines a compact soundbar with a wireless subwoofer to deliver rich audio for movies, TV shows, and gaming at a price point that won't break the bank.

The standout feature is the dedicated center channel speaker that intelligently enhances dialogue and separates voices from background noise, making every word crystal clear even at low volumes. DTS Virtual:X spatial audio creates a convincing surround sound environment that moves around you, eliminating the need for rear speakers. The wireless subwoofer delivers satisfying bass response without cable runs across your room, while Adaptive Sound automatically adjusts audio profiles based on content type for optimized listening in any scenario.

Build quality is solid throughout, with a lightweight but sturdy construction that fits neatly under most TV stands at just under 34 inches wide. Setup is straightforward, particularly if you own a Samsung TV where the soundbar integrates with your existing remote. The system supports seamless Bluetooth switching between two devices, so you can play music from your phone or computer without constant reconnecting, and gaming mode optimizes audio with cross-talk noise cancellation.

The main limitation is room size. Multiple reviewers note this system shines in smaller to medium rooms but may lack impact in larger living spaces. Additionally, while the subwoofer is wireless, both units still require AC power cables, and an HDMI cable must be purchased separately for TV connection. The lack of Wi-Fi means no SmartThings app integration for those seeking full smart home control.

For the price, the Samsung HW-B630F delivers genuine value with easy setup, clear dialogue enhancement, and immersive spatial audio. It's an excellent upgrade from TV speakers for apartment dwellers and those with modest room sizes, though larger spaces or dedicated audiophiles may want to consider higher-tier models.

Audio Performance: 3.1 channel configuration, 370 watts maximum output power, 20 Hz frequency response, DTS Virtual:X spatial audio, Adaptive Sound technology

Connectivity: Bluetooth wireless, HDMI wired, supports simultaneous connection to two Bluetooth devices with seamless switching capability

Physical Dimensions: 33.86 inches wide, 11.64 inches deep, 13.5 inches tall, weighs 15.9 pounds, designed for wall mount or stand placement

Power & Control: Corded electric power for both soundbar and subwoofer, remote control included, compatible with Samsung TV remotes for integrated operation

Compatibility: Works with Samsung TVs, smartphones, gaming consoles including PS5 and Xbox Series X, compatible with Gaming Hub on select Samsung TVs

Warranty: 1-year limited manufacturer warranty

Who Should Buy: This soundbar is ideal for apartment dwellers, small to medium room owners, and Samsung TV users seeking a straightforward upgrade from built-in TV speakers. It's perfect for those prioritizing dialogue clarity in movies and shows, casual gamers, and anyone who wants immersive audio without the complexity of a full surround system.

Who Should Look Elsewhere: If you have a large living room or home theater space, consider higher-wattage models with more channels. Audiophiles seeking Wi-Fi connectivity and smart home integration should explore alternatives. Those needing rear speakers for true 5.1 surround will want a different system.

Setup Considerations: Plan for AC outlets near both the soundbar and subwoofer locations, as both require power cables. Purchase an HDMI cable separately if not included. Allow time for initial configuration if you're not tech-savvy, though Samsung TV integration significantly simplifies the process. Watch setup videos for optimal positioning and sound mode selection.

Value Assessment: At under $240, this represents solid value for a branded 3.1 system with wireless subwoofer. The Adaptive Sound and voice enhancement features justify the price for everyday viewing. This is a practical choice for budget-conscious buyers rather than a premium investment piece.

The Denon DHT-S218 is a 2.1-channel soundbar designed for TV enthusiasts and movie lovers seeking meaningful audio improvement without the complexity of multi-component systems. With dual built-in subwoofers and Dolby Atmos technology, it bridges the gap between basic TV speakers and premium home theater setups. This soundbar targets viewers who want genuine surround sound processing in a compact, easy-to-install package.

Performance-wise, the DHT-S218 impresses with its dialogue clarity and bass response. The Dialog Enhancer function genuinely sharpens voice reproduction, making dialogue-heavy content feel more natural and engaging. Users consistently praise the clarity of voices across movies and TV shows. The dual down-firing subwoofers deliver noticeable bass impact that fills mid-sized living rooms effectively. The 120-watt output provides adequate volume for most viewing scenarios without sounding thin or strained.

Build quality reflects Denon's reputation for solid audio equipment. The soundbar uses metal and aluminum construction with a sleek black finish that complements modern TV setups. At 35 inches wide and just 2.6 inches tall, it fits most TV stands without dominating the entertainment center. The included HDMI eARC cable and remote control are functional, though the LED brightness-based volume indicator feels less intuitive than traditional numerical displays found on competitors.

The main limitation is that this is a soundbar, not a true surround system. While Dolby Atmos processing creates spatial effects, it cannot match the immersion of actual rear speakers or ceiling channels. Additionally, some users report that the volume control's sensitivity can be finicky, requiring gentle remote pressure to achieve fine adjustments. The 2.1 channel configuration also means less precise sound placement compared to 5.1 or 7.1 systems.

The Denon DHT-S218 delivers genuine value for budget-conscious buyers seeking meaningful TV audio improvement. It excels at dialogue clarity, setup simplicity, and integrated bass performance. Recommended for living rooms, dens, and bedrooms where space is limited and ease of installation matters. Skip this if you want true surround sound or plan to expand to a full home theater system later.

Audio Specifications: 2.1 channels, 120 watts total output, 20 kHz frequency response, Dolby Atmos enabled, dual dynamic drivers with down-firing subwoofers.

Connectivity: 4K HDMI eARC, Bluetooth 5.0 with Low Energy Audio support, multi-point Bluetooth, multi-pairing capability, Wi-Fi compatible.

Physical Dimensions: 35 inches wide by 2.6 inches tall by 4.7 inches deep. Weight and exact mounting specifications available in full manual.

Included Accessories: HDMI eARC cable, power cord, remote control with AAA batteries, quick start guide, and safety documentation.

Warranty: 2-year limited warranty from manufacturer covers defects in materials and workmanship.

Who Should Buy: The DHT-S218 suits TV viewers who want noticeable audio improvement without complex installation, apartment dwellers with space constraints, and anyone seeking better dialogue clarity for shows and movies. It works well as an upgrade from TV speakers or as a replacement for older soundbars.

Who Should Look Elsewhere: Serious home theater enthusiasts wanting true surround sound should consider 5.1 or 7.1 systems with dedicated rear speakers. Those prioritizing advanced volume controls or numerical displays may find the LED indicator frustrating. If you need waterproof audio for outdoor use, this indoor-only soundbar won't fit your needs.

Setup Tips: Ensure your TV supports eARC on its HDMI port before purchasing. Switch your TV's audio output to external/HDMI before connecting the soundbar. Place the soundbar on a stable shelf at ear level for optimal sound imaging. Allow 10 minutes for complete setup following the included quick start guide.

Sound Mode Selection: Use Movie mode for films and shows, Music mode for streaming audio, Pure mode for unprocessed critical listening, and Night mode for late-night viewing with reduced dynamic range.

The ULTIMEA Poseidon M60 is a 5.1-channel Dolby Atmos soundbar system designed for home theater enthusiasts who want immersive, cinema-quality audio without the complexity of a full surround speaker setup. At $595, it targets buyers who are upgrading from basic TV speakers and want meaningful audio improvement without committing to a multi-speaker installation. It is equally at home in a bedroom, living room, or dedicated media space of small to medium size.

The standout feature here is the true 5.1-channel Dolby Atmos experience delivered through a single soundbar unit. Two side-firing drivers create a wide soundstage that mimics rear surround channels convincingly, while the dedicated wired wooden subwoofer adds genuine low-end weight. The VoiceMX dialogue enhancement is a real-world differentiator, keeping speech clear and natural even during loud cinematic scenes, a common frustration with standard TV audio. Customers consistently note the night-and-day difference compared to built-in TV speakers.

Build quality is solid for the price range. The soundbar has a slim, low-profile design at just 2.76 inches tall, fitting neatly under most televisions on a console or mounted to a wall. The subwoofer enclosure is constructed from wood, which contributes to its tighter, more accurate bass response compared to plastic alternatives. At 12.6 pounds total system weight, it feels substantial without being difficult to install.

There are a few honest considerations to keep in mind. The bass output at default settings has been noted by some users as requiring adjustment before it reaches its full potential, so expect a brief EQ tuning session after setup. The wired subwoofer connection, while providing a more reliable signal, does restrict placement options compared to wireless models. This system is also better matched to smaller or secondary rooms rather than large open-plan spaces where a more powerful dedicated system would serve better.

Overall, the ULTIMEA Poseidon M60 delivers exceptional value for buyers seeking a straightforward, feature-rich Dolby Atmos upgrade. The combination of app-based EQ control, HDMI eARC connectivity, Bluetooth 5.4, and a genuinely powerful 300W driver configuration makes it one of the most capable soundbar systems in its category. For anyone stepping up from TV speakers or looking for a capable bedroom or secondary room audio solution, this is a highly recommended purchase.

If you are considering the ULTIMEA Poseidon M60, the most important question is what you are upgrading from and what room you plan to use it in. This system is an outstanding choice for anyone moving up from built-in TV speakers, a basic two-channel soundbar, or a budget single-unit system. The jump in audio quality, particularly in dialogue clarity and bass depth, will be immediately noticeable and satisfying.

For room sizing, this system performs best in spaces up to roughly 300 to 400 square feet. Bedrooms, home offices, and mid-sized living rooms are ideal environments. If you have a very large open-plan living area or a dedicated home theater room with high ceilings, you may want to consider a more powerful system or one with physical rear speakers to fill the space adequately.

Connectivity is a key strength here. If your TV supports HDMI eARC, use it. This connection unlocks the full lossless Dolby Atmos signal and provides the best possible audio quality the system can deliver. Optical is available as a fallback, and Bluetooth 5.4 handles wireless streaming from phones and tablets with minimal latency. Gaming console users will also appreciate the low-latency DSP processing, which keeps audio synchronized with fast-paced on-screen action.

Take time to explore the companion app after setup. The default sound profile is a reasonable starting point, but spending ten minutes adjusting the 10-band EQ and experimenting with the 121 presets will help you dial in a sound signature that suits your room acoustics and personal taste. Many users who initially found the bass underwhelming resolved this quickly through the app, so do not judge the system on its out-of-box defaults alone.

The Samsung Q990F soundbar system represents a significant leap forward in home theater audio, designed for serious enthusiasts who want to replace traditional speaker setups with modern, wireless alternatives. This 11.1.4 channel configuration includes a main soundbar, wireless subwoofer, rear speakers, and up-firing channels to create a complete three-dimensional audio environment. The system targets movie lovers, gamers, and music enthusiasts who value immersive sound quality.

Performance is genuinely impressive, with users reporting they hear previously unnoticed details in films like background conversations and ambient effects. The 756-watt output delivers powerful, controlled bass without overwhelming smaller rooms, and the inclusion of rear speakers ensures surround effects feel natural rather than gimmicky. Dolby Atmos integration creates convincing overhead sound effects that enhance action sequences and dramatic moments significantly.

Build quality is solid with the main soundbar measuring 48.5 inches wide and weighing 41.9 pounds, suggesting substantial internal components. The 8-inch subwoofer is compact yet capable, and wireless connectivity means no visible cables running across your entertainment space. The included remote control works adequately, though the Samsung Smart app provides superior functionality and easier menu navigation for most users.

The main drawback involves recent software updates that have destabilized the app for some users, causing unexpected disconnections. Additionally, the system truly shines only when paired with compatible Samsung TVs from 2020 onward, limiting flexibility for those with different TV brands. The premium price point also demands serious commitment to home theater enjoyment.

The Samsung Q990F delivers on its promise of cinematic, immersive audio that noticeably transforms how you experience movies and gaming. For those ready to invest in quality home theater and willing to work through occasional app quirks, this soundbar system represents excellent value compared to traditional speaker setups.

Subwoofer: 8-inch wireless with dynamic driver

Frequency Response: 20 Hz and up
Warranty: 1 year manufacturer limited warranty
Compatibility: Samsung TVs 2022-2025 (Q-Symphony requires 2020-2025 models)

Who Should Buy: Dedicated home theater enthusiasts, gamers seeking immersive audio, and anyone looking to replace traditional speaker systems with modern wireless alternatives. Best suited for medium to large living rooms with compatible Samsung TV models.

Who Should Skip: Budget-conscious buyers, those with non-Samsung TV brands who won't access Q-Symphony features, casual viewers who don't prioritize audio quality, and users with limited space or aesthetic concerns about soundbar placement.

Key Considerations: Ensure your Samsung TV model qualifies for full feature compatibility. Download the Samsung Smart app immediately after setup for superior control compared to the physical remote. Allow the room calibration microphone to properly analyze your space for optimal sound. Check current app reviews before purchase, as recent updates have affected some users' experience.

Installation Tips: Position rear speakers at ear level when seated for best surround effects. Place the subwoofer away from corners to avoid bass buildup. Connect via HDMI eARC to your Samsung TV when possible for seamless audio passthrough and Q-Symphony activation.

The LG S40TR is a 4.1-channel home theater soundbar system designed for consumers who want a genuine surround sound upgrade without the cost or complexity of a traditional AV receiver setup. It includes the main soundbar, a wireless subwoofer, and two wireless rear surround speakers, making it one of the more complete out-of-the-box audio packages available in its price range. It is well suited for living rooms, media rooms, and anyone pairing it with a mid-to-large screen television.

In real-world use, the S40TR delivers a noticeably immersive audio experience, particularly in Cinema mode where the rear speakers and subwoofer work together to create genuine surround presence. Dialogue clarity is strong thanks to the Clear Voice Plus feature, and the Smart Up-Mixer does a commendable job of widening the soundstage even with standard stereo content. Dolby Audio and DTS Digital support ensure compatibility with virtually all modern streaming and disc-based content.

The soundbar itself features LG's crest design with a metal grille that looks premium and helps protect internal components from dust. At just 2.5 inches tall and 28.4 inches wide, it sits neatly in front of most televisions without blocking the screen. The wireless subwoofer is compact enough to tuck beside a couch or entertainment unit, and the overall aesthetic is clean and modern.

There are a few practical considerations worth noting. The rear speakers, while marketed as wireless, do require a cable connection between the two units, and one speaker must be plugged into a mains outlet. First-time setup also requires downloading the LG Soundbar App to activate the rear speakers, a step that is not clearly outlined in the printed instructions. Additionally, the WOW Interface and WOW Orchestra features are only available on compatible LG televisions, so users with other TV brands will not benefit from these integrations.

Overall, the LG S40TR represents outstanding value for anyone seeking a complete home theater audio system on a budget. The combination of wireless connectivity, Dolby and DTS support, smart features, and a stylish build makes it a compelling choice. Minor setup quirks aside, it consistently earns high praise from real users for its immersive sound quality and ease of daily use.

Audio Channels: 4.1 (Soundbar + Wireless Subwoofer + 2 Wireless Rear Speakers). Audio Formats: Dolby Audio, DTS Digital. Connectivity: Bluetooth, Optical Input, USB Port.

Soundbar Dimensions: 28.4 inches wide x 2.5 inches tall x 3.4 inches deep. Subwoofer Dimensions: 6.7 inches wide x 12.6 inches tall x 9.9 inches deep. Total System Weight: 12.9 pounds.

Control Options: Included remote control, LG TV remote via WOW Interface (LG TVs only), LG Soundbar App (iOS and Android). Enclosure Materials: Metal and Plastic. In the Box: Soundbar, wireless subwoofer, two rear speakers, optical cable, rear speaker cable, remote control (AAA batteries included), and warranty card.

Warranty: 1 Year Parts and Labor Limited Warranty. Model Number: S40TR. Compatible Devices: Home Theater systems and Televisions. Speaker Driver Type: Dynamic Driver.

If you are considering the LG S40TR, the most important question is whether you want a true surround sound experience or simply a stereo soundbar upgrade. This system is one of the few in its price bracket that includes rear speakers out of the box, making it a strong choice for movie lovers who want cinematic audio without a full AV receiver setup.

Pairing this soundbar with an LG television unlocks the most value. Features like WOW Interface (single remote control) and WOW Orchestra (combined TV and soundbar speaker output) are exclusive to LG TV compatibility. If you own a Samsung, Sony, or other brand television, you will still get excellent sound, but you will manage the soundbar via its own remote or the LG Soundbar App rather than your TV remote.

Room size is another factor to consider. The 4.1-channel configuration with rear speakers is best appreciated in medium to large living rooms where the surround effect can be felt. In very small rooms, the subwoofer output may feel overpowering at higher volumes, though it is adjustable via the app and remote. For rooms up to around 400 square feet, this system should perform excellently.

If you are comparing this to a basic 2.0 or 2.1 soundbar, the S40TR offers a meaningfully different experience. The rear speakers add genuine spatial audio depth that a standard soundbar simply cannot replicate. For those who primarily watch action films, sports, or play video games, the immersive surround effect is well worth the modest price premium over simpler soundbar options.

The Majority Sierra soundbar is a feature-rich home theater solution designed for TV enthusiasts, gamers, and music lovers who want to upgrade their audio without breaking the bank. With 120W RMS power and Dolby Atmos support, this 2.0.2 channel system delivers immersive sound that transforms everyday viewing into a premium entertainment experience.

The standout feature is its versatility in connectivity. The dual HDMI inputs with ARC support, combined with Bluetooth 5.0, optical, USB, and AUX options, make it compatible with virtually any device in your home. The 4K HDR pass-through ensures your video quality remains pristine while the soundbar handles audio. Real-world performance is impressive, with users praising the powerful, clear sound and rich bass that doesn't overpower dialogue, making it excellent for movies, TV shows, and music alike.

Build quality reflects its mid-range positioning. The plastic enclosure feels sturdy and the sleek 37.8-inch design adds modern aesthetics to any entertainment setup. At 7.8 pounds, it's substantial enough to feel professional while remaining lightweight for wall mounting. The included wall mount kit and comprehensive cable selection make installation straightforward.

The four EQ modes (Movie, Music, News, and 3D) provide useful sound customization for different content types, and the included remote offers simple, intuitive controls. However, one notable concern from customer feedback involves a defective unit that experienced power supply issues, suggesting potential quality control variations. Additionally, this soundbar performs best in medium-sized rooms around 12x14 feet, and may not fill very large living spaces as effectively.

Overall, the Majority Sierra represents excellent value for budget-conscious buyers seeking a capable soundbar with modern features and genuine performance improvements over TV speakers. The 3-year extended warranty provides peace of mind, and the combination of Dolby Atmos, multiple inputs, and customizable sound modes makes it a smart choice for diverse entertainment needs.

Room Size Recommendation: Performs optimally in rooms approximately 12x14 feet to 15x18 feet. Not recommended as primary audio for very large open-concept spaces

Consider Alternatives If: You need a subwoofer for extreme bass emphasis, require weatherproof/outdoor capability, have a very large living room requiring more power, or prefer premium metal construction materials
