Best Soundbars Under $400 for Movies, Music and Home Theater (2026)

A soundbar in this price band can already deliver real Dolby Atmos height, a wireless subwoofer and rear speakers, but the list price of many mid-range systems sits above it. This guide compares eight best soundbars under 400 picks that reach the band on sale or sit inside it, and explains which ones earn the spend for movies, music and TV.

Quick verdict: the best soundbars under 400 at a glance

Only one pick here sits squarely inside the under-400 band at its usual price, while the other seven are mid-range systems that reach the band when discounted. If you want a complete surround set in one box, start with the Hisense AX5140Q or the LG S80TR, and if you want one bar with a big subwoofer, start with the JBL Bar 500.

Quick comparison table

The table below lines up the eight picks by channel layout, what ships in the box, supported formats and the connection each one needs. Read it first to narrow the list to two or three models, then read the matching product sections for the trade-offs that the table cannot show.

How we selected the soundbars in this guide

Every model in this guide is a real product sold in the United States, with published specifications from its manufacturer or trusted retailer and review listings. We compared channel layout, included hardware, Dolby Atmos and DTS:X support, HDMI connections and expansion options, and kept only models that fit the band or reach it on sale.

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. Instead, each pick earns its place for a clear reason, and every pick that lists above the band is flagged as a sale-price pick so the band in the title stays honest.

The best soundbars under 400 for movies and music

Eight systems cover very different rooms and budgets, so the order below follows the decision most buyers face first: a simple bar with a subwoofer, a system with rear speakers, or a complete surround set in one box. Each section states what is in the box and what it gives up.

Samsung HW-Q700D: an Atmos bar with a wireless subwoofer

The Samsung HW-Q700D is the simplest route into this tier: a 3.1.2-channel bar with a wireless subwoofer, Dolby Atmos and DTS:X, and a dedicated centre channel for dialogue. It suits a buyer who wants height effects and real bass without placing rear speakers around the room.

For a mid-range Samsung TV, the HW-Q700D has a practical advantage in Q-Symphony, which can play the soundbar together with the speakers of a compatible Samsung TV. It connects through HDMI eARC, which carries the highest-quality Atmos formats, and its compact subwoofer is easier to place than the larger subwoofers in this guide. The trade-off is the missing rear speakers: surround comes from the bar alone unless the optional rear speakers are added later.

Buy it if you want a tidy Atmos setup with a wireless subwoofer and you may add rears later. Skip it if you want true surround in the box, since this system ships without rear speakers, and check the current price first, because this model lists above the band and only reaches it on sale.

JBL Bar 500: big bass from one bar and a subwoofer

The JBL Bar 500 is the pick for buyers who care most about bass and simplicity. JBL lists a 5.1-channel system with 590 watts of total power, a 10-inch wireless subwoofer, MultiBeam processing and Dolby Atmos, with a PureVoice mode for clearer dialogue.

As a single bar plus a subwoofer, the Bar 500 suits a living room where a clean look matters and rear speakers are not wanted. It connects through HDMI eARC with 4K Dolby Vision passthrough, so a streaming device or console can pass through the bar without losing picture quality. The limits are clear: JBL does not list DTS support for this model, and there is no rear-speaker option, so surround stays virtual rather than coming from speakers behind the sofa.

Buy it if you want deep bass and a simple two-box setup for movies and music. Skip it if you need DTS:X for a Blu-ray collection or you want real rear speakers, and check the current price first, because this model lists above the band and only reaches it on sale.

JBL Bar 800: detachable rears for movie night

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, a 10-inch wireless subwoofer, two up-firing drivers and Dolby Atmos with MultiBeam processing. The bar is 46.2 inches wide in total, so it suits a larger TV, and it connects through HDMI eARC with an HDMI input and optical for older sources. That weight also makes it one of the strongest picks here for action movies, where the large subwoofer gives explosions and music a weight a single bar cannot match. The trade-off is battery life: the rears must return to the bar to recharge.

Buy it if you want real surround and deep bass but you cannot place permanent rear speakers. Skip it if you want a system that is always ready with no charging to think about, and check the current price first, because this model lists above the band and only reaches it on sale.

LG S80TR: complete surround with rear speakers included

The LG S80TR is the pick for an LG TV owner who wants a complete surround system in one purchase. LG lists a 5.1.3-channel system with a wireless subwoofer and wireless rear speakers in the box, Dolby Atmos and DTS:X, and WOW Orchestra for use with a compatible LG TV.

For a living room with an LG OLED of 55 inches or larger, the S80TR has a structural advantage over the bar-only picks: real rear speakers and height channels ship in the box, so nothing needs to be added later. WOWCAST wireless connection can link the bar to a compatible LG TV without a cable, and the rear speakers and subwoofer each need a power outlet even though no audio cable runs to them. The trade-off is size and setup: four boxes take more room and more planning than a single bar.

Buy it if you own a compatible LG TV and you want full surround in one box. Skip it if your room is small or you do not want rear speakers, and check the current price first, because this model lists above the band and only reaches it on sale.

LG S90TY: height effects with a large subwoofer

The LG S90TY is the pick for an LG TV owner who wants height effects and strong bass but is willing to add rear speakers later. LG lists a 5.1.3-channel system with 570 watts of total power, an 8-inch wireless subwoofer, 11 speakers and three up-firing drivers, with Dolby Atmos and DTS:X.

For a main living room, the three up-firing drivers give the S90TY a taller soundstage than the two-driver bars in this guide, and the 8-inch subwoofer adds the low end that makes action scenes feel physical. It connects through HDMI eARC, with Wi-Fi, AirPlay 2 and Chromecast for music, and WOW Orchestra and WOW Interface work with a compatible LG TV. Rear speakers are sold separately, so the system can grow into full surround over time rather than arriving complete.

Buy it if you want strong height effects and bass now with the option to add rears later. Skip it if you want rear speakers in the box, since this system ships without them, and check the current price first, because this model lists above the band and only reaches it on sale.

Vizio Elevate SE: rotating height speakers

The Vizio Elevate SE is the most distinctive pick in this guide, because its height speakers rotate. Vizio lists a 5.1.2-channel system with eight speakers in a 36-inch bar, two auto-rotating adaptive height speakers, a wireless subwoofer and two wired surround speakers, with Dolby Atmos and DTS:X.

For movie night, the rotating drivers turn upward for Atmos content and forward for music and everyday TV, which gives the bar a flexibility the fixed-driver picks cannot match. It connects through HDMI eARC only, with Bluetooth 5.3 for music, and QuickFit lets the bar mount flush under a compatible Vizio TV. The limits matter: there is no optical input and no remote in the box, so the TV remote or the Vizio app controls it, and the surround speakers are wired to the subwoofer rather than fully wireless.

Buy it if you want rotating height speakers and a complete 5.1.2 set in one box. Skip it if you need an optical input or a remote in the box, and check the current price first, because this model lists above the band and only reaches it on sale. The older Vizio Elevate P514a-H6 is a different, earlier model, so check the exact model number and availability before buying.

Polk MagniFi Max AX SR: a large-room surround system

The Polk MagniFi Max AX SR is the pick for a large room, because it is the biggest system in this guide. Polk lists an 11-driver bar with a 10-inch down-firing wireless subwoofer and wireless surround speakers, with Dolby Atmos and DTS:X, and retailer listings describe the complete SR bundle as a 7.1.2-channel system.

For a large living room, the three HDMI inputs plus an eARC output are a real advantage: a console, a streaming device and a Blu-ray player can all connect through the bar. VoiceAdjust lifts dialogue without raising the whole 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 larger TV, and the subwoofer and rears each need a power outlet. The trade-off is size: this is the most boxes and the widest bar in the guide.

Buy it if your room is large and you want a complete surround system with room for three sources. Skip it if your room is small or your TV is under 55 inches, and check the current price first, because this model lists above the band and only reaches it on sale.

Hisense AX5140Q: complete surround inside the band

The Hisense AX5140Q is the only pick here that sits inside the under-400 band at its usual price, and it is also the most complete system for the money. Hisense lists a 5.1.4-channel system with a bar, a wireless subwoofer and wireless rear speakers, 600 watts of maximum total output, Dolby Atmos and DTS:X, and HDMI eARC with 4K HDR passthrough.

For a buyer who wants four height channels and real rears without waiting for a sale, the AX5140Q has a structural advantage over every other pick in this guide: nothing needs to be added later and nothing needs a discount to fit the band. The bar is about 40 inches wide, so it suits a 55-inch TV, and the rear speakers and subwoofer each need a power outlet. The limits are in connectivity and extras: the bar uses Bluetooth only, with no Wi-Fi or app control, so music comes through Bluetooth or the TV connection.

Buy it if you want the most complete surround system that fits the band without a sale. Skip it if you need Wi-Fi music streaming or app control, since this bar offers Bluetooth only, and check the seller before buying, because availability varies by retailer.

What to check before you buy a 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.

How to match the best soundbars under 400 to your room and 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 main living room, a 55-inch TV pairs well with a bar around 40 to 46 inches wide, and a 65-inch or larger TV suits the wider bars in this guide. A small room also changes the bass: a large subwoofer in a small bedroom can overwhelm dialogue, so the dialogue and night modes on the Samsung, JBL and Polk bars are worth using.

HDMI ARC, eARC and optical: what actually matters

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, with one exception to note: the Vizio Elevate SE has an eARC port only, with no optical input at all. Optical carries Dolby Digital 5.1 and stereo, but it cannot carry Dolby Atmos. The JBL Bar 500 and Bar 800 both offer 4K Dolby Vision passthrough, and the LG S90TY offers 4K at 120Hz passthrough for a console.

Do you need Dolby Atmos, DTS:X or a separate subwoofer?

Dolby Atmos adds height to the sound, DTS:X adds a similar object-based effect from a different format, and a separate subwoofer adds the low end that makes action scenes feel physical. Not every buyer needs all three, so match the formats to what the household actually watches.

A separate subwoofer is the single most noticeable upgrade for movies, music and sports, because a slim bar cannot move enough air for deep bass on its own. DTS:X matters mainly for Blu-ray collections and some streaming titles; if the household streams only from services that use Dolby Atmos, a Dolby-only bar such as the JBL Bar 500 or Bar 800 will not miss anything in daily use.

Sale prices, setup and the costs buyers often miss

Seven of the eight picks in this guide list above the band and only reach it on sale, so the price on the day matters more than the list tier. Check the current price from the seller before buying, confirm the exact model number, and remember that a sale price can change or end without warning.

A single bar needs one HDMI cable and a power outlet, while a full system needs power outlets for the subwoofer and each rear speaker, plus a mount if the bar does not sit on the TV unit. Optional rear speakers for the Samsung, LG S90TY and JBL Bar 500 models are sold separately, so a bar can cost far more once the system is complete.

Frequently asked questions about soundbars

The questions below cover the doubts that come up most often before a purchase, from whether a soundbar in this band is worth it at all 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.

Do the best soundbars under 400 include rear speakers?

Some do and some do not, so the box contents matter more than the channel count. The Hisense AX5140Q, LG S80TR, Vizio Elevate SE, Polk MagniFi Max AX SR and JBL Bar 800 all ship with rear speakers, while the Samsung HW-Q700D, JBL Bar 500 and LG S90TY ship without them and need optional rears added later.

Is a soundbar in this band better than TV speakers?

Yes, in almost every case, because TV speakers face backward or downward from a thin cabinet and have little room for bass or a centre channel. A soundbar adds forward-facing drivers, a dedicated centre channel for dialogue and, in most picks here, a separate subwoofer for low end.

What size soundbar fits a 55-inch or 65-inch TV?

A 55-inch TV is about 48 inches wide, so a bar between 40 and 46 inches wide looks balanced, while a 65-inch TV at about 57 inches wide suits the wider bars in this guide. Measure the stand, not the TV. A bar that overhangs the stand is a daily annoyance.

Conclusion

Start with the Hisense AX5140Q for a complete surround system that fits the band without a sale, or the LG S80TR for full surround with an LG TV. If you prefer one bar with a big subwoofer, the JBL Bar 500 and Bar 800 cover that need well. Check the current price, measure your TV and room, and choose the system you will enjoy every day.
