Best TV Soundbars Under $400 Dollars for Movie Nights and TV (2026)

TV speakers leave dialogue thin and movie sound flat, so the right bar matters more than the brand on the box. This guide compares eight best tv soundbars under 400 dollars for movies, sports and everyday TV viewing, from 3.1.2 Atmos bars to complete surround systems with rear speakers in the box.

Quick verdict: the best tv soundbars under 400 dollars at a glance

If you want one short answer, start with the Samsung HW-Q700D for a TV-first Atmos bar, or the Hisense AX5140Q for a complete 5.1.4 system in one box. The other six picks cover detachable rears, a wider bar for a larger TV, rotating height speakers and compact single bars, so read the table first and then the section that matches your room.

Our pick for most living rooms is the Samsung HW-Q700D when it can be found in this tier, because it is built around the TV: a 3.1.2 layout with a dedicated centre channel, a wireless subwoofer and height effects from a single bar. If the sale price does not work out, the Hisense AX5140Q is the safer in-tier pick, since it ships as a complete 5.1.4 system with wireless rears at this budget.

How we selected the soundbars in this guide

Every model here is a real product sold in the United States, with published specifications from its manufacturer. We compared channel layout, included hardware, Dolby Atmos and DTS:X support, HDMI connections, TV size matching and expansion options, and left out models that could not be verified or that duplicated a stronger pick.

This guide is based on published manufacturer specifications and independent review coverage. It does not claim testing of its own, and it does not rank products by review scores, because scores use different methods and change with each update. Seven picks sit above this tier at list price and only fit it on sale, and each one is flagged as such, so check the new-package total before you order.

The best tv soundbars under 400 dollars for your TV

Eight bars cover very different rooms and TV sizes, so the order below follows the decision most buyers face first: a TV-first Atmos bar, a flexible surround system, or a focused fix for size, dialogue, bass or price. Each section states what is in the box, what it gives up, and whether the tier placement depends on a sale.

Samsung HW-Q700D: the TV-first Atmos bar

The Samsung HW-Q700D is the most TV-focused bar in this guide, and that is why it leads the list. It is a 3.1.2-channel system with a dedicated centre channel for dialogue, up-firing drivers for height effects and a wireless subwoofer for the low end, all built around a single bar.

For a TV that needs clearer dialogue and real Atmos height without rear speakers in the room, the HW-Q700D is the natural starting point. It supports Dolby Atmos and DTS:X, and Q-Symphony can play the soundbar together with the speakers of a compatible Samsung TV. The wireless subwoofer adds the bass that a slim bar cannot produce on its own, while the bar itself stays tidy under the TV, with no extra boxes behind the sofa to place or power.

Buy it if you want a TV-first Atmos bar with a subwoofer in the box and you can find it in this tier on sale. Skip it if you want rear speakers included, or if your TV has no HDMI eARC port, since the highest-quality audio formats need that connection.

JBL Bar 800: detachable rears and deep bass

The JBL Bar 800 solves the most common complaint about surround systems: rear speakers that stay in place all week and get in the way. Its two detachable surround speakers run on batteries, so they dock on the bar for everyday TV and move behind the sofa for movie night.

JBL lists a 5.1.2-channel system with 720 watts of total power, two up-firing drivers and support for Dolby Atmos, with a 10-inch wireless subwoofer that gives action movies and music a weight the single bars cannot match. The bar is 46.2 inches wide, so it suits a 55-inch TV and up, and it connects through HDMI eARC plus one HDMI input, with Wi-Fi, AirPlay, Chromecast and Bluetooth 5.3 for music. The rears must return to the bar to recharge, so the system is always ready only if the rears are docked between uses.

Buy it if you want real surround and deep bass but you cannot place permanent rear speakers, and if you find it in this tier on sale. Skip it if you want a system that is always ready with no charging to think about, or if your room is small enough that a single bar and a subwoofer would be enough.

LG S90TY: the wider bar for a larger TV

The LG S90TY is the pick for a larger TV that needs a wider bar to match it, with height effects built in. LG lists a 5.1.3-channel system with 570 watts of total power, 11 speakers and three up-firing drivers, plus an 8-inch wireless subwoofer for the low end.

As a bar for a larger LG TV, the S90TY supports Dolby Atmos and DTS:X, and WOW Orchestra can play the soundbar together with the speakers of a compatible LG TV. Its HDMI eARC connection carries the highest-quality audio from the TV, and 4K at 120Hz passthrough keeps a game console connected through the bar without giving up high refresh rates. Wi-Fi, AirPlay 2 and Chromecast cover music streaming, while rear speakers are sold separately, so the system can grow later if the room allows it.

Buy it if you have a larger LG TV, you play console games at high refresh rates, and you find it in this tier on sale. Skip it if you want rear speakers in the box, or if your TV is small enough that a wider bar would overhang the stand.

Vizio Elevate SE: rotating height speakers

The Vizio Elevate SE is the most unusual system in this guide, because its height speakers rotate. Vizio lists a 5.1.2-channel system with eight speakers and two auto-rotating adaptive height speakers that turn upward for Dolby Atmos and DTS:X and forward for clearer vocals in standard modes.

The system ships with a wireless subwoofer and two wired surround speakers, and the bar is 36 inches wide, which fits a 50-inch TV and up without dominating the stand. It connects through HDMI eARC only, with Bluetooth 5.3 for music, and there is no optical input and no remote in the box, so the TV remote and on-screen controls do most of the work. The rotating speakers give it a real height effect for movies and a wider soundstage for music, which is rare at this tier.

Buy it if you want rotating height speakers and a complete surround system, and you find it in this tier on sale. Skip it if you need an optical input or a remote in the box, or if you want a current model with easy availability, since the exact model number matters here.

Polk MagniFi Max AX SR: big bass and plenty of inputs

The Polk MagniFi Max AX SR is the pick for a household with several sources and a taste for deep bass. Polk lists the base bar as a 5.1.2-channel system with an 11-driver bar, a 10-inch down-firing wireless subwoofer and wireless surround speakers, while retailer listings describe the SR bundle as 7.1.2.

For a TV with a console, a streaming box and a Blu-ray player all connected at once, the three HDMI inputs plus the eARC output are the real advantage here, since most bars in this guide offer one input at most. Dolby Atmos and DTS:X are both supported, VoiceAdjust lifts dialogue without raising the overall volume, and Wi-Fi, Bluetooth, AirPlay 2 and Chromecast cover music from almost any source. The bar is 45 inches wide, so it suits a 55-inch TV and up, and it needs a power outlet for the subwoofer and each surround speaker.

Buy it if you have several HDMI sources, you want a large subwoofer in the box, and you find it in this tier on sale. Skip it if your TV is small, if you want a single tidy bar, or if the channel naming matters to you, since the base and bundle figures differ.

Hisense AX5140Q: complete 5.1.4 surround in one box

The Hisense AX5140Q is the most complete in-tier system in this guide, and that is why it sits near the top for movies. It ships as a 5.1.4-channel system with a bar, a wireless subwoofer and wireless rear speakers, so nothing essential has to be bought separately.

Hisense lists 600 watts of maximum total output, with Dolby Atmos and DTS:X support and an HDMI eARC connection that carries the highest-quality audio from the TV. The bar is about 40 inches wide, which suits a 55-inch TV and up, and 4K HDR passthrough keeps a console or streaming box connected through the bar. There is no Wi-Fi or app control listed, so music comes through Bluetooth, which is a fair trade for a complete surround set at this tier.

Buy it if you want a full surround system in one purchase at this budget and you have room for four boxes. Skip it if you want app control and Wi-Fi streaming, or if your TV has no HDMI eARC port, since the highest-quality audio formats need that connection.

Sony HT-S2000: compact Atmos with built-in bass

The Sony HT-S2000 is the compact Atmos pick for a smaller room that still wants a real low end. Sony lists a 3.1-channel system with 250 watts of total power, Dolby Atmos and DTS:X, and two built-in subwoofers that handle bass without a separate box.

The bar is about 31.5 inches wide, so it fits a 43-inch TV and up and suits a bedroom or a small living room where a separate subwoofer would be in the way. Vertical Surround Engine and S-Force PRO create a wider soundfield from the single bar, and it connects through HDMI eARC with Bluetooth 5.2 for music. Optional Sony subwoofers and rear speakers can be added later, which turns the bar into a larger system over time if the room changes.

Buy it if your room is small, you want Atmos and bass from one bar, and you may add a subwoofer later. Skip it if you want true rear speakers in the box, or if your TV is large enough that a wider bar with a separate subwoofer would suit it better.

JBL Bar 500: the simple bar and subwoofer

The JBL Bar 500 is the simplest two-box pick in this guide, for buyers who want a real subwoofer without rears or extra setup. JBL lists a 5.1-channel system with 590 watts of total power, a 10-inch wireless subwoofer and MultiBeam processing for a wider soundfield from the bar alone.

For everyday TV, the Bar 500 covers the two things that matter most: PureVoice keeps dialogue clear, and the large subwoofer adds the low end that a bar alone cannot produce. It supports Dolby Atmos through HDMI eARC, with 4K Dolby Vision passthrough for a connected source, but it does not support DTS, and rear speakers cannot be added later, so the system stays a bar and a subwoofer. That simplicity is the point for a household that wants better TV sound with no extra boxes to place.

Buy it if you want a straightforward bar and subwoofer package with a large subwoofer, and you find it in this tier on sale. Skip it if you want rear speakers now or later, or if DTS support matters for a Blu-ray collection.

Buying guide: what to check before you buy a TV soundbar

A soundbar is a room purchase as much as an electronics purchase, so the checks below matter more than the channel count on the box. Measure the TV stand, find the HDMI port on the TV, and think about where a subwoofer and any rear speakers will sit.

Sale prices and the tier check

Seven of the eight picks in this guide sit above this tier at list price and only fit it on sale, so the new-package total matters more than any single listing. The Hisense AX5140Q is the only pick that sits inside the tier at its usual price, which makes it the safest choice when the budget is firm.

Check the total for a new unit from a seller you trust before you order, and beware of listings that show a refurbished or open-box unit at a price a new unit cannot match. If a pick cannot be found new in this tier, the Hisense system or a smaller single bar is the honest fallback, rather than stretching the budget for a premium system.

How to match the bar to your TV size

Room size decides the system before price does, so start with the space rather than the specification sheet. A compact bar suits a bedroom or a small apartment living room, while a large open room needs a wider bar, a real subwoofer and rear speakers behind the sofa.

For a 55-inch TV, a bar around 40 to 46 inches wide looks balanced, and a 65-inch or larger TV suits the wider bars in this guide, such as the 46-inch JBL Bar 800 and the 45-inch Polk bar. A small room also changes the bass: a large subwoofer in a small bedroom can overwhelm dialogue, so the dialogue modes on the JBL, Sony and Polk bars are worth using.

HDMI eARC, dialogue and rears in the box

The connection on the back of the TV decides which sound formats the soundbar can receive, so check it before you buy. HDMI eARC carries the highest-quality audio, including Dolby Atmos from Dolby TrueHD, while standard HDMI ARC carries compressed Atmos and Dolby Digital 5.1.

Every pick in this guide uses HDMI eARC, which fits a TV-first purchase, and several add a separate HDMI input for a console or streaming box. Dialogue is the other TV-first check: a dedicated centre channel and a dialogue mode, such as PureVoice on the JBL bars or VoiceAdjust on the Polk, matter more than channel count when the household keeps turning the volume up for speech.

Frequently asked questions

The questions below cover the doubts that come up most often before a purchase, from whether real Atmos is possible at this tier to which size fits a common TV. Each answer follows the same rule as the rest of this guide: it states what the specifications support, and it names the case where the answer changes.

Can you get real Dolby Atmos in the best tv soundbars under 400 dollars?

Yes, and this tier is where real Atmos stops being rare. The Hisense AX5140Q ships with up-firing height speakers, the JBL Bar 800 has two up-firing drivers, the Samsung HW-Q700D and the Vizio Elevate SE both bring real height effects, and the Sony HT-S2000 brings Atmos into a single bar.

The JBL Bar 500 is the exception to watch: it supports Dolby Atmos, but it has no up-firing drivers, so the height effect comes from processing rather than real height speakers. If height effects are the main reason for the purchase, choose a system with real up-firing speakers and an HDMI eARC connection, since the highest-quality Atmos formats need that port.

Is a soundbar with rear speakers always better than a single bar?

No, because rear speakers only help when the room lets them sit behind the sofa with power nearby. A single bar with a subwoofer can sound better in a small room, a bedroom or a rented home where permanent rears are not practical, and it is easier to move.

Rear speakers earn their place for movies in a living room with a clear spot behind the seating, and the JBL Bar 800 is the most flexible answer when that spot is only free on movie night. If the household mostly watches news and everyday TV, a tidy single bar such as the Sony HT-S2000 or the JBL Bar 500 is the smarter use of the budget.

What should you check before you buy a TV soundbar in this tier?

Check three things before you order: the new-package total, the HDMI port on the TV, and where the subwoofer and any rear speakers will sit. Seven picks in this guide only fit this tier on sale, so the total for a new unit matters more than any single listing.

Measure the TV stand, since a bar that overhangs the stand is a daily annoyance, and confirm that the TV has an HDMI eARC port if you want the highest-quality Dolby Atmos. Finally, count the power outlets: the subwoofer and each rear speaker need one, even when no audio cable runs to them.

Conclusion

Start with the Samsung HW-Q700D for a TV-first Atmos bar with a subwoofer, or the Hisense AX5140Q for a complete 5.1.4 system at its tier. If detachable rears or a wider bar matters more, the JBL Bar 800 and the LG S90TY cover those needs. Measure your TV and room, check the HDMI connection, and confirm the new-package total before you order.
