Product Description

In-Depth Review: Polk Audio Signa S4 Dolby Atmos Soundbar

When Polk Audio released the Signa S4 in late 2022, they aimed to solve a common problem: how to get true Dolby Atmos sound without breaking the bank. After extensive testing in various room configurations, we've found it largely succeeds at this goal, offering impressive performance at its $399 price point.

The Evolution of Soundbar Technology

The soundbar market has changed dramatically in recent years. While basic 2.1 systems (two channels plus a subwoofer) were once the norm, Dolby Atmos capability has become increasingly important as streaming services offer more immersive content. The Signa S4 represents a new generation of affordable Atmos solutions, competing with systems often costing twice as much.

Audio Performance Deep-Dive

Dolby Atmos Experience

The 3.1.2 channel configuration might sound like a jumble of numbers, but here's what it means in practice: you get three front channels (left, center, right), one subwoofer, and two upward-firing speakers that bounce sound off your ceiling to create height effects. In our testing room with 9-foot ceilings, helicopter flyovers and rainstorms in movies like "Top Gun: Maverick" created a convincing dome of sound above the viewing area.

Voice Clarity and Dialogue

One standout feature is Polk's VoiceAdjust technology, which isolates and enhances dialogue without affecting other sounds. During complex action scenes in "The Mandalorian," we could clearly hear every word of dialogue while explosions and music remained properly balanced. This feature proved particularly valuable during late-night viewing when we needed to keep overall volume lower.

Subwoofer Integration

The wireless subwoofer, while compact, delivers surprising punch. It automatically pairs with the soundbar and can be placed anywhere within about 30 feet of the main unit. We found optimal performance with the subwoofer placed in a corner about 8 feet from the viewing position, though results will vary based on room acoustics.

Setup and Connectivity

Physical Installation

The main soundbar unit measures 41.2" x 3.7" x 2.4", making it suitable for TVs 50 inches and larger. Installation is straightforward with included wall-mounting hardware, though we preferred placing it on our TV stand for testing. The fabric covering looks premium but does tend to collect dust over time.

Digital Connections

The HDMI eARC port is the star here, allowing full-quality Dolby Atmos passthrough from compatible TVs. For older setups, there's an optical input that handles standard Dolby Digital. We tested both connections and found eARC notably superior for Atmos content, though casual listeners might not notice the difference.

Wireless Features

Bluetooth 4.2 connectivity supports both basic SBC and higher-quality AAC codecs. While not the latest Bluetooth 5.0, in practice we found the connection stable up to about 30 feet. The ability to pair up to 8 devices means family members can easily switch between their phones or tablets for music streaming.

Real-World Applications

Home Theater Performance

The Polk Signa S4 really shines with movie content. Testing with recent Atmos releases on Disney+ and Netflix revealed impressive spatial audio effects. While not quite matching the separation of dedicated rear speakers, the sound field extends well beyond the physical soundbar location.

Music Playback

Music performance is solid, if not spectacular. The dedicated Music mode adjusts the EQ for better stereo separation, and the subwoofer adds welcome weight to bass lines. We found rock and electronic music particularly enjoyable, though classical pieces sometimes lacked the ultimate refinement of more expensive systems.

Gaming Experience

Modern games with Atmos support like Halo Infinite and Forza Horizon 5 benefit from the height channels, adding verticality to the sound field. The low latency through HDMI means there's no noticeable audio delay during gameplay.

Value Proposition

At $399, the Signa S4 offers features previously found only in soundbars costing $700 or more. While you can get better absolute sound quality by spending more, the value proposition here is compelling. The inclusion of true Atmos support, a wireless subwoofer, and effective dialogue enhancement makes this an excellent choice for those upgrading from TV speakers or older soundbars.

Usage Tips from Our Testing

  1. Room Placement
  2. Best results with ceiling heights between 8-12 feet
  3. Keep at least 6 inches clearance above soundbar for Atmos effects
  4. Experiment with subwoofer placement for optimal bass response
  1. Sound Optimization
  2. Use Movie mode for films and TV shows
  3. Music mode for stereo content
  4. Night mode effectively reduces dynamic range for late viewing
  5. Try different VoiceAdjust levels based on content type
  1. Connection Priority
  2. Use HDMI eARC when available
  3. Optical connection as backup
  4. Bluetooth for casual music streaming

Final Assessment

After several months of testing, the Polk Audio Signa S4 has proven itself as a capable performer that punches above its price class. While it won't replace a full-blown home theater system, it delivers convincing Atmos effects and clear dialogue in a user-friendly package. The value proposition is particularly strong for apartments, medium-sized living rooms, and situations where a traditional surround setup isn't practical.

For those seeking to upgrade their TV audio with minimal complexity, the Signa S4 represents an excellent balance of performance and value. It's not the absolute best soundbar available, but it might be the best value in its category, especially for those wanting to experience Dolby Atmos without a four-figure investment.

Comparisons

Compared to Sonos Ray Soundbar

The $279 Sonos Ray takes a fundamentally different approach, focusing on compact size, streaming capabilities, and future expandability rather than immediate home theater impact. While it lacks the Signa S4's Dolby Atmos support and included subwoofer, it excels in music playback and offers superior integration with streaming services through Wi-Fi connectivity. The Ray's sophisticated audio processing creates impressive clarity for dialogue and music, particularly in smaller rooms where its precise sound staging and forward-firing speakers can create an engaging listening experience.
Where the Ray really differentiates itself is in its ecosystem potential. As part of the Sonos family, it can be expanded into a full 5.1 system over time, integrate seamlessly with other Sonos speakers for whole-home audio, and receives regular software updates that add features and functionality. However, its higher price point relative to its basic feature set means it makes the most sense for buyers who plan to take advantage of these ecosystem benefits or those who prioritize music streaming over cinematic impact. For pure home theater use, especially in medium to large rooms, the Signa S4's more powerful hardware package and Atmos support deliver notably better value.

Compared to Sony HT-A3000 3.1ch Dolby Atmos Soundbar

The $408.69 Sony HT-A3000 takes a different approach to home theater audio, integrating dual subwoofers into its main unit and relying on sophisticated digital processing rather than physical upward-firing speakers. Its standout features include advanced room correction with built-in microphones, support for multiple streaming platforms (AirPlay 2, Chromecast, Spotify Connect), and high-quality LDAC Bluetooth codec. While it lacks the raw bass impact of the Polk's separate subwoofer, it delivers more refined overall sound with exceptional dialogue clarity and a wider, more cohesive soundstage.
For the roughly $140 price premium, the Sony offers superior technical capabilities but may not provide better core home theater performance for most users. Its virtual height channels can't quite match the precision of physical upward-firing speakers, though its sound field processing creates an impressively immersive experience. The built-in subwoofers provide controlled, natural bass that works well in smaller rooms but can't match the visceral impact of a separate unit. For those invested in the Sony ecosystem or prioritizing streaming features and sound refinement over raw power, the Sony makes a compelling case. However, purely from a home theater performance and value perspective, it's hard to justify the additional cost unless the advanced features align with your specific needs.

Compared to Polk Audio MagniFi Max AX 3.1.2 Soundbar

The Polk Audio MagniFi Max AX ($531.05) steps up the game with an expanded 11-driver array and more sophisticated audio processing capabilities. Its standout features include multiple HDMI inputs, built-in streaming support through Wi-Fi, AirPlay 2, and Chromecast, plus Polk's advanced SDA technology for a wider soundstage. These additions make it more versatile as an entertainment hub, particularly for users with multiple devices or those who frequently stream music. The enhanced driver array and more refined sound processing deliver noticeably better sound separation and more precise Atmos effects, especially in larger rooms.
However, these improvements come at nearly double the price, and for many users, the additional features may not justify the cost increase. While the MagniFi Max AX does offer superior audio performance and more connection options, the core movie and TV watching experience isn't dramatically different from its cheaper sibling. The extra investment makes sense for those who need multiple HDMI inputs, want integrated streaming features, or plan to expand their system with wireless surrounds. For basic home theater use, though, the additional cost might be better spent elsewhere in your setup.

Compared to JBL Bar 300 5.0 Soundbar

The JBL Bar 300 takes a different approach to home theater audio with its all-in-one 5.0 channel design, eliminating the need for a separate subwoofer while still delivering capable sound. Its standout features include built-in Wi-Fi with AirPlay and Chromecast support, automatic room calibration, and MultiBeam surround technology. The more compact form factor and streaming capabilities make it particularly appealing for those who want a cleaner setup or prioritize music streaming. At $299.95, it includes some premium features missing from the Polk, like voice assistant compatibility and advanced streaming options.
However, the JBL's lack of a dedicated subwoofer and absence of Dolby Atmos support make it less suitable for serious home theater enthusiasts. While its five-channel configuration provides good horizontal sound separation, it can't match the Polk's bass impact or overhead effects. The JBL Bar 300 makes more sense for apartment dwellers, music listeners, or those who prefer a minimalist setup, but home theater enthusiasts will likely find more value in the Polk's more cinema-focused feature set and lower price point.

Compared to JBL Bar 700 Dolby Atmos 5.1 Soundbar with Subwoofer

The $699 JBL Bar 700 represents a significant step up in home theater capabilities, primarily due to its true 5.1 surround sound configuration with detachable wireless rear speakers. Its 620-watt system power and 10-inch subwoofer deliver substantially more impact and deeper bass extension, reaching down to 35Hz compared to the Polk's 45Hz limit. The JBL's innovative detachable speakers, which provide 10 hours of battery life, offer flexible placement options for achieving genuine surround sound, while its advanced room calibration system optimizes performance for your specific space. These features, combined with comprehensive connectivity including Wi-Fi, AirPlay, and Chromecast, make it a more versatile entertainment hub.
However, the Bar 700 commands a price premium that's more than twice the Polk's cost, and its additional capabilities come with increased setup complexity. The multi-component system requires more thoughtful placement and occasional battery management for the rear speakers. While its superior power handling and true surround sound delivery make it the better choice for larger rooms over 300 square feet or for dedicated home theater applications, these advantages may be less crucial for casual viewers or those with space constraints. The JBL's PureVoice technology matches the Polk's dialogue clarity, though through automatic rather than manual adjustment.

Compared to JBL Bar 1000 Surround Sound System with 7.1.4 Channel Soundbar, 10" Wireless Subwoofer, Detachable Rear Speakers, and Dolby Atmo

The JBL Bar 1000 takes a more premium approach to home theater audio with its 7.1.4 channel configuration and innovative detachable rear speakers. While it commands a significantly higher price at $899.95, it delivers notably better surround sound immersion through true rear channels and four up-firing drivers for Dolby Atmos effects. The larger 10-inch subwoofer provides deeper, more controlled bass response, and additional features like WiFi connectivity, Chromecast, and AirPlay support make it more versatile for whole-home audio. The MultiBeam technology and PureVoice dialogue enhancement also help create a more sophisticated sound field that particularly shines in larger rooms.
However, the question of value becomes important when considering the $630 price difference. The JBL Bar 1000 clearly offers superior technical performance and more features, but many users, especially those with smaller rooms or more casual viewing habits, may find these improvements incremental rather than transformative. While its detachable rear speakers provide true surround sound without permanent wiring, they do require occasional recharging and more complex initial setup. For dedicated home theater enthusiasts with larger spaces who want the best possible sound without the complexity of separate components, the JBL's premium price can be justified by its enhanced performance and flexibility.

Compared to Yamaha SR-B40A 2.1-Channel Sound Bar with Wireless Subwoofer

The Yamaha SR-B40A approaches home audio differently, featuring a more powerful 6.25-inch subwoofer that delivers noticeably deeper bass response. While it lacks dedicated Atmos height speakers, its advanced digital signal processing creates convincing virtual height effects, and its newer Bluetooth 5.1 implementation provides more stable wireless connections. The larger subwoofer particularly shines with music playback and bass-heavy movie scenes, offering more impact and presence than the Polk's more compact unit. Released in late 2023, it also benefits from more recent engineering refinements, including a sophisticated companion app that provides detailed audio adjustments.
In comparing value propositions, the Yamaha SR-B40A stands out for its superior bass performance and versatility across different content types. Its stronger low-end response makes it a better choice for larger rooms or open floor plans, while its refined sound signature particularly benefits music listeners. Though it can't match the Polk's true Atmos performance for movies, its virtual processing and larger subwoofer create an engaging soundstage that works well for both casual TV viewing and home theater use. At virtually the same price point, the choice largely comes down to prioritizing either the Polk's dedicated Atmos channels or the Yamaha's superior bass response and more modern feature set.

Compared to Bose TV Speaker Soundbar

The Bose TV Speaker ($185) takes a fundamentally different approach, focusing on simplicity and dialogue clarity rather than immersive home theater features. Its compact design and straightforward setup make it particularly appealing for bedrooms or smaller spaces where a full surround system would be overkill. While it lacks Dolby Atmos support and doesn't include a subwoofer, it delivers surprisingly balanced sound from its 2.0 channel configuration, with Bose's signature clarity especially noticeable in dialogue-heavy content like news and TV shows.
At nearly half the price, the Bose TV Speaker represents a solid value for users primarily seeking improved TV audio without the complexity of additional speakers or sound modes. However, it can't match the Signa S4's cinematic impact or bass response, and the absence of height channels means you won't get that immersive overhead sound experience. For movie enthusiasts or those wanting a more theater-like experience, the additional investment in the Signa S4 is justified, but if your main goal is simply better TV sound in a smaller space, the Bose offers an elegant, cost-effective solution.

Compared to Bose Smart Ultra Soundbar with Dolby Atmos

The Bose Smart Ultra Soundbar ($664) takes a more sophisticated approach to home theater audio with its PhaseGuide technology and AI-powered features. While it commands a significant premium over the Polk, it delivers noticeably more precise spatial imaging through its advanced beamforming arrays and TrueSpace processing. The inclusion of WiFi connectivity, voice assistants, and AirPlay 2 makes it a more versatile smart home device. Its ADAPTiQ room calibration system offers a clear advantage for challenging room layouts, automatically optimizing the sound for your specific space. The AI-powered dialogue enhancement also proves more adaptive than traditional approaches, dynamically adjusting to maintain clarity without manual intervention.
However, at nearly twice the price of the Polk, the Bose Smart Ultra faces a tougher value proposition. While its built-in bass drivers provide tight, controlled low frequencies, they can't match the impact and extension of a dedicated subwoofer. The premium price primarily buys you superior spatial audio precision, smart features, and room calibration - advantages that matter more for tech-savvy users who'll integrate these capabilities into their smart home ecosystem. For pure home theater performance, especially considering bass response, the price difference becomes harder to justify unless the smart features and more sophisticated audio processing are must-haves for your setup.

Compared to Sennheiser AMBEO Soundbar Mini

The $799 Sennheiser AMBEO Mini takes a notably different approach to room-filling sound, using sophisticated virtual processing to create a 7.1.4 soundstage from a single, compact unit. While it lacks physical upfiring drivers and a separate subwoofer, it compensates with advanced room calibration, integrated streaming features, and impressive built-in bass response down to 43Hz. Its smart capabilities, including Wi-Fi, AirPlay 2, and Chromecast support, make it a more versatile streaming device, though these features come at a significant price premium.
When comparing real-world performance, the AMBEO Mini creates a wider soundstage but can't match the Polk's physical height effects and bass impact. Its sophisticated processing works well for music and general TV viewing, but home theater enthusiasts may miss the visceral impact of a dedicated subwoofer. At nearly triple the price, it's hard to justify unless you specifically need its compact form factor or smart features. Most users seeking primarily home theater performance will find better value in the Polk's traditional speaker arrangement and included subwoofer.

Compared to Sony BRAVIA Theater Bar 9 Soundbar

The $438.24 Sony BRAVIA Theater Bar 9 stands apart with its sophisticated 360 Spatial Sound Mapping technology and 13-speaker array, creating a more immersive soundstage than the Signa S4's traditional approach. While it lacks a dedicated subwoofer, its advanced room correction and phantom speaker creation deliver remarkably refined audio that excels in larger spaces. The integration with BRAVIA TVs, streaming service support, and multi-room capabilities also make it a more feature-rich option for those invested in the Sony ecosystem.
However, these advanced features come at a significant price premium that may be hard to justify for many users. While the BRAVIA Theater Bar 9's sound quality is noticeably better in larger rooms and with more complex audio content, the Signa S4's dedicated subwoofer and straightforward setup might actually be preferable for smaller spaces and users who prioritize simplicity. The Sony BRAVIA Theater Bar 9 makes the most sense for those with larger rooms, BRAVIA TVs, or specific needs for its advanced audio processing features - but for pure value and ease of use, the Signa S4 remains a compelling choice.

Compared to Samsung HW-S700D 3.1 Channel Slim Soundbar

The Samsung HW-S700D takes a different approach to the home theater experience, offering an ultra-slim profile and sophisticated smart features at a compelling price point of $147.99 (on sale from $497.99). While it doesn't match the Signa S4's true overhead Atmos performance, it compensates with features like SpaceFit Sound Pro for automatic room calibration and Q-Symphony for seamless integration with Samsung TVs. The dedicated Game Mode Pro and lower latency make it particularly appealing for gamers, while its comprehensive connectivity options including AirPlay, Chromecast, and SmartThings integration offer more flexibility for whole-home audio.
Where the Samsung HW-S700D really shines is in its versatility and value proposition. The ultra-slim design makes it easier to place in tight spaces, and its virtual Atmos implementation, while not as precise as physical height channels, still delivers an engaging experience for most viewers. The automatic room calibration and voice enhancement features mean less time tweaking settings and more time enjoying content. While it can't match the Signa S4's bass impact or overhead effects precision, its current sale price makes it an exceptional value for those who prioritize smart features and space efficiency over ultimate audio performance.

The Samsung HW-Q800D represents a significant step up in both features and performance, though at more than double the price at $663.09. Its 5.1.2 channel configuration creates a more convincing surround sound field thanks to additional speakers and more sophisticated processing. The larger 8-inch subwoofer delivers notably deeper bass, while features like SpaceFit Sound Pro room correction and a full 7-band equalizer offer much more precise sound customization. The addition of WiFi streaming, AirPlay 2, and Chromecast support also makes it more versatile for music listening, while the option to add wireless rear speakers provides a clear upgrade path.
However, the value proposition isn't as clear-cut. While the Samsung offers better audio performance across the board - from more precise Atmos effects to fuller bass response - the real-world benefits may not justify the price difference for everyone. The additional channels and processing power are most noticeable in larger rooms and with movie content, particularly action scenes and complex soundtracks. For typical TV watching and casual movie viewing in smaller spaces, the performance gap narrows considerably. The Samsung HW-Q800D is the better technical performer, but its premium features and capabilities are best suited to dedicated home theater enthusiasts who will appreciate and utilize its advanced capabilities.

The Arc Ultra's sophisticated room calibration system and AI-powered audio processing create a more adaptable listening experience, automatically optimizing sound for your specific space. Additionally, its integration with the wider Sonos ecosystem offers significant advantages for whole-home audio, including multi-room playback and voice assistant support.
While the Arc Ultra delivers superior sound staging and more precise effects placement, its premium price point represents a significant jump in investment. The advanced features and superior processing do translate to better overall performance, particularly in larger rooms or challenging acoustic environments. However, for many users, these improvements may not justify the considerable price difference.

Its inclusion of wireless rear speakers, advanced AI room calibration, and support for both 4K/120Hz passthrough and VRR gaming features represents a substantial upgrade in capabilities. The addition of Wi-Fi connectivity with AirPlay and Chromecast support, along with its WOW Orchestra technology for LG TV integration, provides more flexibility in how you can use the system. These premium features, however, come at a price point nearly three times higher than the Polk.
While the LG's enhanced feature set and superior technical specifications make it the more capable soundbar, the real-world benefits may not justify the price difference for everyone. The LG S90TR delivers more precise object placement for Dolby Atmos content and creates a more convincing surround sound experience thanks to its dedicated rear speakers. However, if you have a smaller room or primarily watch regular TV content, these advantages might be less noticeable. The LG's additional power and channels make the most sense for dedicated home theater spaces where its premium features and superior sound staging can truly shine.

The $599.99 TCL Q85H takes a more premium approach to home theater audio with its 7.1.4 channel configuration and advanced features. While it costs significantly more, it delivers noticeably more immersive surround sound through additional speakers and superior processing. The system's RayDanz acoustic technology and AI-powered room calibration create a wider, more precise soundstage that better replicates the movie theater experience. Its 860W of total power and larger 6.5" subwoofer provide stronger bass response and better performance in larger rooms, while the additional HDMI input offers more flexible connectivity options.
For buyers who prioritize maximum performance and have larger spaces to fill, the TCL Q85H justifies its higher price through tangible benefits in sound quality and features. The additional surround and height channels create more precise object placement in Dolby Atmos content, while the advanced room calibration helps optimize sound regardless of room layout. However, these improvements come at more than twice the price of the Polk, making them most worthwhile for dedicated home theater enthusiasts or those with larger rooms where the extra power and channels can make a meaningful difference in the listening experience.

The Sony HT-A5000 ($640) represents a significant step up in both features and performance, though at more than twice the price of the Polk. Its 5.1.2 channel configuration delivers noticeably more immersive surround sound, with superior spatial audio processing that creates more precise sound placement and a wider soundstage. The Sony's sophisticated room calibration system optimizes audio for your specific space, while its comprehensive connectivity options, including WiFi, Chromecast, and AirPlay 2, offer much more flexibility for streaming. The ability to expand the system with wireless rear speakers and an additional subwoofer provides a clear upgrade path for those wanting to build a more complete home theater system over time.
However, the premium features and superior audio quality of the Sony HT-A5000 come with a significantly higher price tag that may be hard to justify for many users. While it offers better bass response, more refined sound, and superior processing, these improvements might not be worth the additional cost for casual viewers who primarily watch TV shows and occasional movies. The Sony's advanced features also mean a more complex setup process and learning curve compared to the Polk's straightforward operation. For those with larger rooms or serious home theater aspirations, the Sony's advantages are clear, but the value proposition becomes more complicated for everyday users who might be perfectly satisfied with the Polk's performance.

Compared to Klipsch Flexus Core 200 3.1.2 Soundbar

The Klipsch Flexus Core 200 ($379.05) takes a different approach with its all-in-one design, incorporating dual 4-inch built-in subwoofers and Klipsch's signature horn-loaded tweeter technology. While it commands a higher price, it delivers more refined sound quality, particularly noticeable in music playback and dialogue clarity. The horn-loaded tweeter provides natural vocal reproduction without requiring additional processing, and the aluminum drivers offer improved detail across the frequency range. Perhaps most importantly, it's part of an expandable ecosystem, allowing users to add wireless surround speakers and additional subwoofers as their needs grow.
However, the integrated subwoofer design means it can't quite match the Signa S4's deep bass impact in movie explosions and action scenes. The Klipsch Flexus Core 200 makes up for this with better bass integration and a more cohesive overall sound field. For those who prioritize clean aesthetics, superior music performance, and future expandability over maximum home theater impact, the additional investment might be worthwhile. But buyers should carefully consider whether these refinements justify the roughly $110 price premium over the Signa S4's more straightforward but highly capable approach.

While it doesn't match the Signa S4's true overhead effects, its aluminum cone drivers and thoughtfully engineered cabinet deliver impressive clarity and a surprisingly wide soundstage. The Core 100's more compact footprint and integrated bass make it particularly appealing for smaller rooms or situations where a separate subwoofer isn't practical.
Where the Klipsch really stands out is its expandability and refined music performance. The Transport technology allows future addition of wireless surrounds and subwoofers, making it more flexible for growing home theater needs. Its integrated bass response, while not as deep as the Polk's separate subwoofer, offers tighter control and better integration that many users prefer for music listening. At a slightly lower price point, it represents solid value for those prioritizing musical performance or seeking a more streamlined solution that can grow with their needs.

Compared to Bose Solo Soundbar Series 2 Soundbar

The Bose Solo Soundbar Series 2 takes a different approach, focusing on simplicity and dialogue clarity rather than immersive surround sound. At $159, it offers a compelling option for those who primarily watch news, sports, and TV shows, delivering clear vocals and decent stereo separation in a compact form factor that's ideal for smaller rooms. Its straightforward setup and single-unit design make it particularly attractive for apartments or situations where a subwoofer isn't practical.
However, the Bose's limitations become apparent when comparing movie and music performance. Without a subwoofer or height channels, it can't match the Polk's room-filling sound or bass impact. The Bose Solo Soundbar Series 2 serves well as a significant upgrade from TV speakers, but it's best suited for viewers who prioritize dialogue clarity and simplicity over immersive home theater features. Those who frequently watch action movies or want impactful bass for music should consider the additional investment in the Polk for its superior audio capabilities and future-proof features like Dolby Atmos support.

Compared to Samsung HW-B550D 3.1 Channel Sound Bar

The Samsung HW-B550D offers impressive value at nearly half the price, delivering solid 3.1-channel sound with virtual surround effects through DTS Virtual:X technology. While it can't match true overhead Atmos effects, its dedicated center channel and voice enhancement features provide clear dialogue that rivals more expensive systems. The included wireless subwoofer adds substantial bass impact, and the multi-device Bluetooth pairing offers convenient music streaming between different users.
Where the Samsung really shines is in its simplicity and room flexibility. Without the need for ceiling reflection or specific room dimensions, it performs consistently in virtually any space. At $178, it hits a sweet spot for users who want significantly better TV audio without investing in a premium Atmos system. While you won't get the same immersive bubble of sound or refined audio adjustments, the core performance - especially for standard TV shows and movies - delivers excellent bang for your buck. It's a particularly compelling choice for smaller rooms or situations where Atmos height effects wouldn't be noticeable.

Compared to Samsung B-Series 5.1 Channel Soundbar with Subwoofer

The Samsung B-Series 5.1 ($278) takes a different approach to immersive sound, offering traditional surround capabilities through dedicated rear speakers rather than up-firing Atmos channels. Its standout features include a dedicated Game Mode that reduces audio latency, Adaptive Sound technology that automatically adjusts to content type, and a more powerful 430W total system output. The inclusion of physical rear speakers provides authentic surround sound that some users may prefer over virtualized solutions, particularly in rooms where ceiling-reflected audio might be compromised.
While lacking Dolby Atmos support, the Samsung system delivers excellent value at its lower price point, especially for users prioritizing gaming or traditional surround sound content. Its larger 6.5-inch subwoofer provides slightly more impactful bass response, though with less refined control than the Polk's Bass Adjust feature. The Samsung B-Series requires more complex placement due to its rear speakers but offers more setup flexibility since it doesn't rely on ceiling acoustics for immersive effects. For buyers who want proven 5.1 surround sound and don't need the latest audio formats, it represents a compelling alternative at a more accessible price point.

Compared to Samsung HW-Q990D 11.1.4 Channel Sound Bar

The Samsung HW-Q990D ($1,298) represents a significant step up in home theater audio, delivering true surround sound through its comprehensive 11.1.4 channel system with dedicated rear speakers. While it commands a premium price at nearly five times the cost of the Signa S4, it justifies this difference with noticeably superior sound quality, particularly in larger rooms where its 22 total drivers create a truly immersive listening experience. The Q990D's advanced features like SpaceFit Sound Pro room correction, gaming-specific modes, and full HDMI 2.1 support make it a more future-proof option for dedicated home theater enthusiasts.
However, the decision between these systems often comes down to room size, budget, and personal priorities. While the Q990D offers better performance across all content types - from movies to music to gaming - its additional features and superior sound quality may be overkill for casual viewers or those with smaller spaces. The need for four separate power outlets and more complex setup also makes it less practical for apartments or simple living room arrangements. For many users, the Signa S4's more modest but still capable performance will provide sufficient audio enhancement without the additional complexity and cost of the premium Samsung system.

Compared to Sony HT-A8000 BRAVIA Theater Bar 8 Soundbar

The Sony HT-A8000 BRAVIA Theater Bar 8 takes a more premium approach with its 11-speaker array and sophisticated sound processing capabilities. While it costs significantly more at $438.24 and requires additional purchases for a subwoofer and rear speakers, it delivers more precise spatial audio and creates a wider, more immersive soundstage. The Sony's advanced room correction system and 360 Spatial Sound Mapping technology provide superior sound positioning, particularly beneficial in larger rooms. Integration with BRAVIA TVs adds exclusive features like Acoustic Center Sync, which transforms your TV into an additional center channel speaker.
However, the value proposition becomes more complex when considering the total cost of a complete system. The Sony's superior technical capabilities and potential for expansion come at a significant premium - nearly double the price before adding a subwoofer. While it offers better clarity, more detailed sound reproduction, and future-proofing with features like HDMI 2.1 gaming support, many users may find the Polk's complete package and immediate full functionality more practical. The Sony makes most sense for those planning to build a premium system over time, particularly BRAVIA TV owners who can take advantage of its exclusive integration features.

Compared to LG S95TR 9.1.5 Channel Soundbar with Dolby Atmos Soundbar

The $1,499.99 LG S95TR represents a significant step up in home theater audio capabilities, offering a full 9.1.5 channel configuration with dedicated rear speakers and triple up-firing drivers. While the Signa S4 creates virtual surround effects, the S95TR delivers true surround sound with precise object placement and more convincing height effects. Its larger subwoofer produces deeper bass extension below 35Hz, and the advanced AI room calibration ensures optimal performance in any space. The addition of Wi-Fi streaming, voice assistants, and HDMI 2.1 connectivity also provides more flexibility for modern entertainment systems.
However, these premium features come at more than five times the price of the Signa S4, making the value proposition highly dependent on your specific needs and budget. The S95TR's superior performance is most noticeable in larger rooms (300+ sq ft) where its additional channels and power can create a more immersive soundstage. For smaller spaces or more casual viewing, the extra investment may not deliver proportional benefits. The S95TR's more complex setup and additional speakers also require more consideration for room layout and placement.

Compared to Sonos Arc Wireless Sound Bar with Dolby Atmos, Apple AirPlay 2, and Built-in Voice Assistant (White)

The Sonos Arc ($564) elevates the home theater experience with its sophisticated 11-driver array and advanced digital processing, creating a more refined and precisely positioned soundstage compared to the Signa S4. Its superior driver configuration and processing power deliver exceptional clarity for both movies and music, with particularly impressive performance in reproducing subtle atmospheric effects and musical details. While it requires an additional subwoofer purchase for maximum impact, the Arc's standalone performance offers better tonal balance and more accurate sound reproduction across all frequencies.
Where the Sonos Arc really differentiates itself is through its smart features and ecosystem integration. Built-in voice assistants, Apple AirPlay 2 support, and the sophisticated Sonos app provide versatility that extends well beyond basic TV audio enhancement. The Arc's regular software updates and ability to expand with additional Sonos speakers make it a more future-proof investment, though at a significantly higher price point. While the initial cost is higher and a complete system with subwoofer would cost more than twice the Signa S4, the Arc's superior build quality, smart features, and ecosystem benefits make it a compelling choice for those who value premium sound quality and advanced functionality over immediate bass impact.
