We reviewed eight soundbars ranging from compact all-in-one bars to full 5.1ch systems with dedicated subwoofers. Whether you want clean dialogue for late-night viewing or a room-filling home theater experience, there is an option on this list for you.

Quick answer
This guide compares 8 picks, with Polk Audio Signa S2 Ultra-Slim Soundbar with Wireless ranked first.
Pros
- Incredibly compact design doesn't interfere with TV viewing or aesthetic
- Wireless subwoofer provides surprising bass impact without floor space or wires
- Clear dialogue quality makes dialogue-heavy content like news and shows more enjoyable
- Easy setup with multiple cable options and intuitive remote control
- Solid build quality and reliability backed by multi-year warranty
Cons
- Limited to 5.1 channels, so not a replacement for true surround sound setups
- 2-inch woofer and small tweeter mean bass and treble won't match larger premium systems
- Plastic enclosure feels less premium than higher-end competitors
The Polk Audio Signa S2 is a compact soundbar and wireless subwoofer combo designed for anyone tired of tinny TV audio but lacking the space or budget for a full home theater setup. It's perfect for apartment dwellers, modern living rooms, and anyone whose TV sits at eye level where a bulky soundbar would be an eyesore.
Performance is where the Signa S2 truly shines. The combination of five full-range drivers in the soundbar plus the wireless subwoofer creates a surprisingly spacious soundfield. Polk's VoiceAdjust technology keeps dialogue front and center, making every word crisp and clear, while Dolby Digital decoding adds genuine immersion without the complexity. Bluetooth streaming lets you pull music directly from your phone, turning your TV area into a casual music zone.
Build quality is respectable for the price point. The ultra-slim bar measures just 2 inches tall, so it tucks neatly under most TV screens without blocking your remote sensor or picture. The wireless subwoofer stays out of sight, and setup requires just plugging in cables and powering on, the included HDMI cable gets you started immediately.
The main limitation is scale. This isn't a replacement for larger, more expensive systems, and the smaller drivers mean you won't get the extended bass response or treble detail of premium models. The plastic enclosure also feels less robust than metal competitors, though it holds up well for regular use.
The Signa S2 deserves consideration if you want meaningful audio improvement without breaking the bank or your living room layout. It delivers genuine value for casual viewers and streaming enthusiasts, with enough performance for most content types.

The Sonos Beam Gen 2 is a premium compact soundbar designed for people who want immersive Dolby Atmos surround sound without cluttering their living room. It excels as both a dedicated home theater speaker and a multiroom music hub, making it perfect for anyone invested in the Sonos ecosystem or starting their premium audio journey.
The standout feature is Dolby Atmos support, which creates a convincing 3D soundstage that elevates movie watching and gaming. Dialogue reproduction is crisp and clear, while the panoramic sound design handles directional effects naturally. Beyond TV, the Beam Gen 2 shines as a multiroom speaker, letting you stream music, podcasts, and radio from services like Spotify, Apple Music, and more throughout your home with the same high quality.
Design is thoughtful and minimalist. The polycarbonate enclosure fits elegantly on a shelf or TV stand, and setup is genuinely simple with just an HDMI cable and power cord. The built-in microphone enables voice control compatibility, while Trueplay tuning automatically calibrates the sound to your room's acoustics for optimal performance without manual tweaking.
The main limitations are the compact form factor and price. Bass response, while respectable for the size, doesn't match dedicated subwoofers. At $499, it sits at a premium price point, though the versatility as both theater and music hub justifies the investment for many users. The system also relies on WiFi, so features like multiroom audio aren't available without connectivity.
The Beam Gen 2 is an excellent choice for upgrading your TV audio and creating a foundation for a whole-home audio system. It delivers professional-grade surround sound in a form factor that works for most living spaces, backed by a year's warranty and Sonos's reputation for customer support.
Best for cord-cutters and streaming enthusiasts who want exceptional audio for movies, shows, and music without traditional cable boxes or large speaker systems. If you value versatility, clean aesthetics, and the ability to expand gradually, the Beam Gen 2 fits perfectly.
Consider this soundbar if you own other Sonos products or plan to build a multiroom setup. It also works well as an entry point for first-time premium audio buyers who want to understand quality sound without overwhelming complexity.
Skip this if you need thundering bass for action movies, want a fully wireless solution, or have a tight budget under $300. If you're committed to a single room only, a traditional soundbar with subwoofer might offer better value.

Pros
- Excellent value for money with genuine 2.1 channel sound and real subwoofer at under $80
- Intuitive one-touch switching between Movie, Music, and Dialogue modes adapts to any content
- Minimal footprint and slim profile work in cramped spaces where full surround systems won't fit
- Multiple input options cover nearly every device from smart TVs to older equipment
- Strong customer rating of 4.3 stars from over 1,600 reviews shows real-world reliability
Cons
- Limited to 2.1 channels means no true surround sound for immersive home theater setups
- 3-inch subwoofer is smaller than dedicated units, so bass performance won't match high-end systems
- Entry-level construction uses plastic housing which may feel less premium than higher-priced alternatives
The BESTISAN SE11M is a 2.1 soundbar that bridges the gap between tinny TV audio and full home theater systems. It's ideal for apartment dwellers, casual gamers, and anyone wanting noticeably better TV sound without space or budget constraints. At 16.5 inches wide and 2.8 inches deep, it fits neatly in front of most televisions while delivering 120W of peak power.
The standout feature is the three EQ modes that actually work: Movie Mode creates spacious sound for films and shows, Music Mode pumps up bass for streaming and gaming, and Dialogue Mode cuts through background noise for news and podcasts. The dedicated 3-inch subwoofer handles lows convincingly for a compact all-in-one unit, while dual full-range drivers keep mids and highs crisp. Real users report noticing a significant improvement over TV speakers in both clarity and impact.
Build quality is straightforward: ABS plastic body with metal accents keeps weight down at 1.5kg. The remote is responsive, and HDMI ARC integration means your TV remote can control volume once configured. Connectivity spans Bluetooth 5.3 (10-meter range), HDMI ARC, Optical, USB, and 3.5mm aux, covering everything from smart TVs to older devices. The eco-friendly packaging and 12-month warranty (plus 60-day replacement guarantee) show the maker stands behind the product.
Limitations are honest ones: this is 2.1 channel audio, not surround sound, so cinephiles expecting immersive 5.1 or 7.1 setups will find it basic. The subwoofer, while effective, won't shake a room like a 10-inch standalone unit. And the plastic construction, while durable, doesn't feel premium compared to soundbars costing twice as much.
Verdict: The BESTISAN SE11M is a smart choice for improving TV and gaming audio on a tight budget. It won't replace a dedicated home theater system, but it delivers noticeable improvements in sound quality, design flexibility, and ease of use that justify its price point.
Audio: 2.1 channels, 120W peak power, 80dB signal-to-noise ratio, 20 Hz to 20 kHz frequency response.
Subwoofer: 3-inch woofer diameter, built-in design.

With enhanced dialogue processing and wide, natural sound tuning, this stereo soundbar focuses on clarity and spread rather than deep bass extension. That makes it a strong fit for someone prioritizing clear TV audio over rattling low end, especially since it runs fine without pairing to any subwoofer.
Pros
- Dedicated center tweeter and dialogue enhancement technology improve speech clarity
- Compact 2-inch-tall design stays out of the way
- Simple single-cable setup with HDMI-CEC remote control support
- Expandable later with Bose Bass Module 500 or 700 if more bass is wanted
Cons
- No built-in subwoofer, and only 35 watts of output overall
- Bass heft is limited for movie enthusiasts and larger rooms
The Bose TV Speaker makes its subwoofer stance explicit: it ships with no built-in subwoofer and runs at just 35 watts, relying instead on two angled full-range drivers and a dedicated center tweeter tuned for dialogue clarity. For anyone deciding whether a soundbar needs a sub, this is a model built around the opposite priority, voice clarity over bass weight, and it succeeds at that narrower job. Built-in Dolby decoding and dialogue mode controls add polish without extra boxes or cables, and setup is a single optical or HDMI connection. The honest answer this soundbar gives is: it depends on what you're listening for. If bass matters to you, Bose sells the Bass Module 500 or 700 as a later add-on, which confirms that the stock unit intentionally leaves low end on the table. For dialogue-first TV watching, that absence barely registers.
Dimensions: 23.38 inches wide, 2.21 inches tall, 4.02 inches deep. Remote: 4.1 inches tall.
Audio & Connectivity: 35-watt stereo output. Bluetooth 4.2 with 30-foot range. HDMI-ARC, optical audio input, and 3.5mm AUX input. USB for service only.
Drivers: Two full-range drivers angled for wide sound, one center tweeter for vocal clarity.
Power & Control: Corded electric with 5-foot power cord. Remote control with pre-installed lithium-ion battery (20-hour average battery life). Button and remote control methods.
Warranty & Includes: 1-year limited warranty. Includes remote control, optical cable, power cord, and quick start guide. Wall brackets sold separately.
This compact 2.0ch model outputs surround sound from a single slim cabinet, which matters when you want fuller staging without adding a wireless sub to the room. Its wall mount design keeps the footprint minimal, making it a practical standalone choice for viewers skipping the extra bass unit.
Pros
- Built-in bass reflex speaker delivers room-filling sound without a separate subwoofer
- Voice enhancement technology sharpens dialogue on streaming and older broadcasts
- Flexible connectivity with HDMI ARC/eARC, optical, USB, and Bluetooth
- Slim 38-inch profile fits under most TVs
Cons
- 2-channel design means bass is present but not punchy in larger rooms
- HDMI eARC setup can require extra patience with TV menus
If you're asking whether a soundbar needs a subwoofer, the HTS100F is a useful real-world test case: it ships as a 2.0-channel bar with a built-in bass reflex speaker and no separate subwoofer unit. At 120 watts, it genuinely improves on tinny TV speakers and fills smaller rooms with satisfying sound, backed by S-Force Pro Front Surround to widen the soundstage beyond what you'd expect from two channels. For dialogue-heavy content like streaming shows and older broadcasts, its voice enhancement technology does real work without any extra hardware. Where the lack of a subwoofer shows up is in bass-heavy material: action movies and music with deep low end will sound present but not punchy. For apartments, bedrooms, and secondary TVs where a sub isn't practical anyway, that's a reasonable tradeoff. It's a clear example of a soundbar built to work well without a subwoofer, as long as your room and expectations match that design.
Audio Output: 2-channel surround with S-Force Pro Front Surround technology
Power Output: 120 watts total
Dimensions: 38 inches W x 6 inches D x 6 inches H
Connectivity: HDMI eARC, optical digital, USB, Bluetooth (10-meter range)
Speaker Type: Bass reflex driver with built-in tweeter
Frequency Response: 64.4 Hz and above
Mounting: Wall-mountable or tabletop placement
Warranty: 1 year manufacturer limited warranty
Included: Remote Commander with batteries, optical cable, AC cord, wall mount template, quick start guide
Good for anyone with a smaller TV in a bedroom, apartment, or secondary room who wants clearer dialogue and fuller sound without adding a subwoofer. Also good for budget-conscious buyers who want flexible HDMI ARC, optical, USB, and Bluetooth connections in one slim unit. Skip it if you want strong bass for action movies in a larger room, since the built-in bass reflex speaker has real limits without a dedicated sub.
Built with a passive radiator enclosure, this bar mount model reinforces low end directly through its full-range drivers instead of relying on a separate box. For a desk setup where a subwoofer is impractical, that passive radiator design does the work of filling in bass that a standalone soundbar would otherwise lack.
Pros
- Dual full-range drivers plus passive radiators reach up to 90dB without a subwoofer
- Single USB-C cable keeps desk setups clean
- 14-zone Chroma RGB syncs with other Razer gear
- Compact bar-mount design fits under most monitors
Cons
- No subwoofer connectivity, so bass depends entirely on the built-in drivers
- Bluetooth range of 10 meters requires reasonable proximity for best performance
The Leviathan V2 X answers the subwoofer question in an unusual way: it is not a TV soundbar at all, so the comparison works differently. For a PC setup, this bar relies entirely on dual full-range drivers with passive radiators instead of a separate sub, pushing output up to 90dB from a footprint that tucks under a monitor. There is no subwoofer port, so what you hear is what the drivers alone produce, which works fine for game effects, voice chat, and general desktop audio but will feel thin if you want chest-thumping bass. The tradeoff is intentional: a single USB-C cable, 14-zone Chroma RGB, and Bluetooth 5.0 keep the desk clean and the setup simple. If your question is whether you need a subwoofer specifically for gaming at a desk, this soundbar's answer is that its built-in drivers are the whole solution, no add-on required, though bass-heavy content will expose the ceiling of that approach.
Audio Performance: Stereo output, 90dB maximum volume, Dolby Digital 2.0 encoding, 20kHz frequency response, dual full-range drivers with passive radiators
Connectivity: USB Type-C (power and audio), Bluetooth 5.0, 10-meter wireless range, dual connectivity protocols for seamless device switching
Design: Compact bar-mount form factor, black color, 1-inch speaker size, passive radiator enclosure material, fits under standard monitors
Customization: 14-zone Razer Chroma RGB with dynamic in-game effects, Razer Audio App and Razer Synapse software control, app-based audio device toggling
Warranty and Support: 1-year manufacturer limited warranty, includes USB Type-C cable and product documentation
Good for PC gamers and desktop users who want better sound than onboard speakers without adding a subwoofer or extra cables to their setup. Skip it if you want real low-end rumble for bass-heavy games or music, since there is no subwoofer connectivity to expand into. Also skip it if you're shopping for a TV soundbar, since this is designed for computer setups, not living rooms.
Offering three customizable equalizer modes, this detachable tabletop unit lets you dial in bass response manually instead of depending on a dedicated subwoofer. The 2-in-1 design also adapts across TV, PC, and projector setups, useful for anyone wanting adjustable low end in a single self-contained bar.
Pros
- 80W output across 4 drivers without needing a separate subwoofer
- Auto volume boost keeps dialogue audible without constant remote adjustments
- Three EQ presets tailor sound to movies, music, or news
- Compact 2-in-1 detachable design with four mounting options
Cons
- No subwoofer means limited deep bass for action movies or music
- ARC mode reportedly needs volume pushed to 80%+ for adequate output
If you're trying to decide whether a soundbar needs a subwoofer, the Assistrust KY-8000 is a good case study for a no-sub setup done right. It's a pure stereo soundbar, no bass module included or needed, and it compensates with 4 drivers pushing 80W of output plus auto volume boost to keep dialogue clear without a separate low-end box. The three preset EQ modes (movie, music, news) help it adapt to different content so you're not missing the thump of a subwoofer because the mix is already tuned per scenario. For anyone whose room, budget, or furniture layout can't accommodate an extra subwoofer unit, this shows that a single tabletop or wall-mounted bar can still cover TV dialogue, music, and casual gaming audio. It won't replicate deep cinematic bass, but that's an intentional tradeoff for simplicity. Connectivity is flexible (Bluetooth, ARC, optical, AUX), and the 2-in-1 detachable design keeps the footprint compact across four mounting options, reinforcing that this is a space-saving, subwoofer-free solution rather than a scaled-down home theater system.
Audio Performance: 80W total power output with 4 dynamic drivers, stereo audio mode, 20 kHz frequency response, 2 audio channels
Connectivity: Bluetooth 5.0, HDMI ARC, Toslink optical, 3.5mm auxiliary, compatible with TV, projector, gaming consoles, laptops, tablets, and smartphones
Design: 17 inches wide by 3.5 inches deep by 2.5 inches tall, weighs 2.97kg, matte black finish, 60% recycled ABS plastic plus metal reinforcement
Features: Three customizable EQ modes, auto volume boost, detachable design, four placement options, remote control with battery requirement, wall-mount and tabletop bases included
Warranty and Support: 2-year manufacturer warranty, 24/7 online customer support, 60-day hassle-free replacement policy
Buy this if you want a no-subwoofer soundbar solution for a TV, PC, or gaming setup where space or simplicity matters more than deep bass. It suits apartments, dorms, or secondary rooms. Skip it if you specifically want the chest-thumping low end a dedicated subwoofer provides, or if you rely heavily on Bluetooth with a Roku TV, since some users report compatibility issues there.
Pros
- True 5.1 channel configuration with genuine surround speakers creates convincing immersive soundscape
- 600W power output handles both action sequences and quiet dialogue without distortion
- Wireless subwoofer eliminates cable clutter and simplifies placement options
- Multiple input options ensure compatibility with TVs, streaming devices, and gaming consoles
- Dialogue enhancement and bass control features improve everyday viewing comfort
Cons
- Limited to 10 meter Bluetooth range, which may not cover large homes or outdoor spaces
- Entry-level sound modes may not match the customization available on higher-end theater systems
- No app control or voice assistant integration for modern smart home compatibility
The Sony HT-S40R is a complete 5.1 channel soundbar system designed for viewers who want genuine surround sound without the complexity of a full AV receiver setup. It includes a soundbar, wireless subwoofer, and rear speakers, making it ideal for upgrading existing TV audio or building a first home theater system.
The standout feature is the 600W power output driving all five channels, which translates to room-filling sound during action scenes and clear dialogue during conversations. The included wireless subwoofer handles bass without requiring dedicated wiring, while the rear speakers position surround effects convincingly around the listening area. Sound modes adapt to different content types, and the dialogue enhancement feature makes dialogue crisp during late-night viewing.
Build quality is solid with a metal and plastic construction that feels durable. The soundbar sits compactly under most TVs, and the wireless rear speakers eliminate the need for long speaker cables running around your room. Color-coded connections make initial setup straightforward even for non-technical users.
The main limitations are the 10-meter Bluetooth range and lack of smart home integration or app control. The sound modes, while effective, offer less granular customization than premium systems. These tradeoffs are typical at this price point and rarely concern average users.
The HT-S40R is an excellent choice for anyone looking to upgrade from built-in TV audio to a genuine surround sound experience without significant complexity or expense. It's particularly well-suited for streaming enthusiasts and casual gamers who value immersion over professional audio calibration.

How to Choose Between a Soundbar With or Without a Subwoofer
Room Size and Bass Expectations
In a small bedroom or home office, a soundbar without an external subwoofer often delivers plenty of low-end depth. The Bose TV Speaker – Soundbar for TV with Bluetooth handles this scenario well, using two angled full-range drivers to create a wide, natural sound without needing extra hardware.
In larger living rooms, bass frequencies tend to get absorbed by furniture and open space. That is where a system like the Sony HT-S40R 5.1ch Home Theater Soundbar earns its place, delivering 600W of total power with real rear speakers and a dedicated subwoofer for genuine surround coverage.
Built-In Subwoofers vs. Wireless External Units
Some soundbars solve the bass problem without adding a separate box to your living room. The BESTISAN 2.1ch Sound Bar with Built-in Subwoofer fits a dedicated subwoofer driver inside a compact 16.5-inch bar, giving you felt bass without extra cables or floor space.
A wireless external subwoofer like the one bundled with the Polk Audio Signa S2 Ultra-Slim Sound Bar for goes further, physically moving air in a separate enclosure. This produces a more physical, low-frequency impact that built-in drivers simply cannot fully replicate at higher volumes.
Content Type and How You Actually Watch
If most of your viewing is news, sports, or dialogue-heavy dramas, a subwoofer is rarely necessary. The Sony S100F 2.0ch Compact and Slim Soundbar for TV includes a dedicated voice enhancement mode that prioritizes speech clarity, making it a strong choice for content where bass is not the priority.
For action movies, gaming, or music listening, having that low-end extension transforms the experience. The Sonos Beam Gen 2 – Black handles this through Dolby Atmos processing and a 3D soundstage that creates a sense of scale, even without a dedicated subwoofer alongside it. For a deeper look at building out a cinematic viewing room, the best laser projector picks for home cinema pair naturally with any of these soundbar setups.
Connectivity and System Expandability
How a soundbar connects to your TV matters as much as how it sounds. HDMI ARC is the gold standard since it carries audio both ways and lets your TV remote control volume. Most options here, including the Sound Bar for Smart TV, Soundbar from Assistrust, support ARC alongside optical and AUX inputs, giving you flexibility regardless of your TV’s age.
If you are building a desktop or gaming setup rather than a living room system, the Razer Leviathan V2 X, PC Soundbar with Full-Range takes a different approach entirely. It runs on a single USB-C cable, adds Razer Chroma RGB lighting, and pairs via Bluetooth 5.0 for seamless switching between your PC and mobile devices. For anyone building out a gaming space, pairing this with one of the best 4K TVs for gaming is a natural combination. You might also want a reliable signal path, so reviewing the best HDMI 2.1 cables for gaming PCs is worth your time.
Final Thoughts
A soundbar does not always need a subwoofer, but the right answer depends entirely on your space and how you use it. If you want a clean, no-clutter upgrade with serious bass included, the Polk Audio Signa S2 Ultra-Slim Sound Bar for bundles a wireless subwoofer into a straightforward package that works out of the box. If you want the most immersive, full-room surround experience on this list, the Sony HT-S40R 5.1ch Home Theater Soundbar delivers real 5.1ch audio with rear speakers and a dedicated subwoofer that genuinely recreates the cinema feel at home.
Frequently Asked Questions
Does a soundbar need a subwoofer to sound good?
Not necessarily. Many soundbars deliver surprisingly full sound on their own, especially in smaller rooms. A subwoofer adds low-frequency extension that benefits action movies and music, but for dialogue-focused content like news or drama, a standalone bar often performs well without one.
What is the difference between a built-in subwoofer and a wireless external one?
A built-in subwoofer is a dedicated driver housed inside the soundbar itself, keeping your setup compact. A wireless external subwoofer is a separate speaker unit that communicates with the bar over a wireless connection, allowing it to move more air and produce deeper, more physical bass. The difference becomes more noticeable at higher volumes and in larger rooms.
Can I add a subwoofer to a soundbar later?
Some soundbars are designed to expand over time. The Bose TV Speaker, for example, is compatible with the Bose Bass Module 500 or 700, letting you start simple and add bass later as your budget allows. Not all soundbars support this, so check compatibility before assuming you can upgrade. Reviewing the specs for your specific model in 2026 before purchasing is the best approach.
Is a 5.1ch soundbar system worth it over a basic soundbar?
If you watch a lot of films and want audio that genuinely surrounds you, a 5.1ch system with rear speakers and a subwoofer is a meaningful upgrade over a single bar. For casual TV watching or smaller spaces, the added hardware may be more than you need. You can browse the full range of home theater options in the TVs and Home Theater category to compare what fits your setup.
Common questions
What crossover frequency should you set for a soundbar and subwoofer?
Most setups work well with a crossover between 80Hz and 120Hz, which sends low bass to the subwoofer and keeps everything above that in the soundbar. The exact point depends on how small the soundbar's own drivers are. A soundbar with tiny built-in speakers benefits from a higher crossover, while one with larger drivers, like the Sony HT-S40R, can handle more low end before handing off to the sub.
Does room size affect whether a soundbar needs a subwoofer?
Yes, room size matters because larger spaces need more air moved to deliver noticeable bass. A compact model like the Sony S100F suits small bedrooms or offices where deep bass is less critical. Bigger living rooms benefit from a dedicated subwoofer, like the one included with the Polk Signa S2 or the Sony HT-S40R system, since a soundbar alone often struggles to fill a larger room with low frequencies.
How does wireless sub pairing work with a soundbar?
Wireless sub pairing works by syncing the subwoofer to the soundbar automatically on first power-up, usually within seconds. Systems like the Polk Signa S2 and Sony HT-S40R include a wireless subwoofer that connects without running cables across the room. If the pairing light stays blinking, powering both units off and back on in sequence usually resolves it, since most modern soundbar subs reconnect without needing a manual setup menu.
