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 soundbars under 400 dollars for movies, music, sports and everyday viewing, from full surround systems with rear speakers to compact bars, and explains who each model suits.
Quick verdict: the best soundbars under 400 dollars at a glance
If you want one short answer, start with the JBL Bar 1000, or the Hisense AX5140Q for a complete 5.1.4 system in one box. The other six picks cover a tidy single bar, a compact Atmos system, a low-cost 5.1 package and three premium systems that only fit this tier on sale, so read the table first and then the section that matches your room.
| Model | Best for | Channels | In the box | Sound formats | Connection |
|---|---|---|---|---|---|
| JBL Bar 1000 | Detachable rears, deep bass | 7.1.4 | Bar, wireless subwoofer, detachable rears | Dolby Atmos, DTS:X | HDMI eARC |
| Hisense AX5140Q | Complete 5.1.4 surround | 5.1.4 | Bar, wireless subwoofer, wireless rears | Dolby Atmos, DTS:X | HDMI eARC |
| Samsung HW-S60D | Tidy all-in-one Atmos bar | 5.0 | Bar only | Dolby Atmos, DTS Virtual:X | HDMI eARC |
| Vizio M51a-H6 | True 5.1 surround for less | 5.1 | Bar, wireless subwoofer, satellite speakers | Dolby Atmos, DTS:X | HDMI eARC |
| Sony HT-S2000 | Compact Atmos, built-in bass | 3.1 | Bar only | Dolby Atmos, DTS:X | HDMI eARC |
| Samsung HW-B750D | Affordable 5.1 package | 5.1 | Bar, wireless subwoofer | Dolby Digital 5.1, DTS Virtual:X | HDMI ARC |
| LG S95TR | Full home theater, larger room | 9.1.5 | Bar, wireless subwoofer, wireless rears | Dolby Atmos | HDMI eARC |
| Vizio Elevate P514a-H6 | Rotating height speakers | 5.1.4 | Bar, wireless subwoofer, satellite speakers | Dolby Atmos, DTS:X | HDMI eARC |
Our pick for most living rooms is the JBL Bar 1000 when it can be found in this tier, because its detachable rears solve the hardest part of surround sound: placing speakers behind the sofa. 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 or trusted review coverage. We compared channel layout, included hardware, Dolby Atmos and DTS:X support, HDMI connections 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. Three picks sit above this tier at list price and only fit it on sale or clearance, and each one is flagged as such, so check the new-package total before you order.
The best soundbars under 400 dollars in detail
Eight bars cover very different rooms and budgets, so the order below follows the decision most buyers face first: a flexible surround system, a complete in-tier package, 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.
JBL Bar 1000: detachable rears and deep bass
The JBL Bar 1000 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 7.1.4-channel system with 880 watts of total power, four up-firing drivers and support for Dolby Atmos and DTS:X. The 10-inch wireless subwoofer is the largest in this guide, and it gives action movies and music a weight that the single bars cannot match without an add-on subwoofer. The bar connects through HDMI eARC, and 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 or clearance. 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.
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.
Samsung HW-S60D: the tidy all-in-one Atmos bar
The Samsung HW-S60D is the pick for buyers who want Dolby Atmos without a subwoofer box or rear speakers in the room. Samsung lists a 5.0-channel system with seven speakers and 200 watts of total power, with built-in woofers and a passive radiator doing the low-end work.
As an all-in-one bar, the HW-S60D suits a main living room where a clean look matters more than the deepest bass. It supports Dolby Atmos and DTS Virtual:X, and wireless Dolby Atmos works with a compatible Samsung TV, while Q-Symphony can play the soundbar together with the speakers of a compatible Samsung TV. The bar is about 26.4 inches wide, so it fits smaller stands and TVs, and optional subwoofer and rear speakers can be added later if the room changes.
Buy it if you want one tidy bar with Atmos height effects and no extra boxes, and you may add a subwoofer later. Skip it if you want deep bass for action movies in the box, or if your room is large enough that a system with a real subwoofer and rears would fill it better.
Vizio M51a-H6: true 5.1 surround for less
The Vizio M51a-H6 is the value surround pick in this guide, because it puts real satellite speakers and a wireless subwoofer in the box at the lower end of this tier. Vizio lists a 5.1-channel system with nine speakers, a 6-inch wireless subwoofer and satellite speakers for true surround.
The bar is 36 inches wide, which fits a 50-inch TV and up without dominating the stand, and it supports Dolby Atmos and DTS:X with an HDMI eARC connection and a separate HDMI input. The Atmos effect here is virtualised, with no up-firing drivers, so the height effect is subtler than on the bars with real height speakers. The satellites are wired to the subwoofer, so the subwoofer needs a spot near the seating area rather than anywhere in the room.
Buy it if you want true 5.1 surround with a subwoofer at the lower end of this tier and you can place the subwoofer near the sofa. Skip it if you want real up-firing height speakers, or if the model is no longer sold new where you shop, since this is a 2021 model and availability varies.
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.
Samsung HW-B750D: the affordable 5.1 package
The Samsung HW-B750D is the affordable pick in this guide, and it earns that place by including the two things that matter most at its tier: a dedicated centre channel and a real wireless subwoofer. Samsung lists a 5.1-channel system with 400 watts of total power and a wireless subwoofer.
For a low-cost step up from TV speakers, the HW-B750D is a practical choice without the cost or the boxes of a premium system. The centre channel keeps dialogue clear, the subwoofer adds the low end that a bar alone cannot produce, and optional SWA-9200S rear speakers can be added later for true surround. There is no Dolby Atmos and no HDMI eARC port, so this is a 5.1 system that plays surround sound well rather than a height-effects system.
Buy it if you want a complete bar-and-subwoofer package at the lowest tier in this guide and you can live without Dolby Atmos. Skip it if you need Dolby Atmos, DTS:X or an eARC connection, or if the new-package total does not check out in this tier, since listings for this model have straddled the tier line.
LG S95TR: full home theater for a larger room
The LG S95TR is the largest system in this guide, and it leads on channel count for a big living room. LG lists a 9.1.5-channel system with a bar, a wireless subwoofer and wireless rear speakers, so it ships as a complete home theater in one purchase.
As a full system for a larger LG OLED, the S95TR supports Dolby Atmos and WOW Orchestra, which can play the soundbar together with the speakers of a compatible LG TV. It suits TVs of 55 inches and up, where a wide bar and rear speakers have room to breathe, and the rear speakers put real sound behind the sofa for movies. The trade-off is tier placement: this is a premium system whose list tier sits above this budget, so it only fits here when found on a deep sale.
Buy it if you have a large room and a larger LG TV, and you find it in this tier on sale. Skip it if your room is small, if you want a system that is in this tier at its regular list price, or if your TV is not a compatible LG model for the WOW Orchestra features.
Vizio Elevate P514a-H6: rotating height speakers on a sale budget
The Vizio Elevate P514a-H6 is the most unusual system in this guide, because its height speakers rotate. Vizio lists a 5.1.4-channel system with 18 speakers, four up-firing drivers and 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 with an 8-inch driver and two satellite surround speakers, and it connects through HDMI eARC with Bluetooth, Wi-Fi and Chromecast for music. The rotating speakers give it a real height effect for movies and a wider soundstage for music, which is rare at this tier. The trade-off is age and tier placement: this is an older model whose list tier sits above this budget, so check availability and the new-package total before you order.
Buy it if you want rotating height speakers and a complete 5.1.4 system, and you find it in this tier on sale or clearance. Skip it if you want a current model with easy availability, or if you cannot confirm that the listing is for a new unit from a seller you trust.
Buying guide: what the under-400 tier buys over the under-300 tier
The step from the under-300 tier to the under-400 tier is where rear speakers and real height effects start to appear in the box, so the extra budget buys completeness rather than a louder bar. A buyer who stretches to this tier should expect more hardware, not just a better version of the same single bar.
What the under-400 tier buys over the under-300 tier
At the under-300 tier, most systems are a bar with a subwoofer and no rears, or a single bar with virtual Atmos. This tier changes that: the Hisense AX5140Q and the Vizio Elevate ship with wireless rears in the box, the JBL Bar 1000 adds detachable rears, and the subwoofers get bigger.
The bars also get wider at this tier, which matters for a 55-inch or 65-inch TV, and more of them carry HDMI eARC and a separate HDMI input. The trade-off is that the most complete systems at this tier are the ones most likely to need a sale to fit it, so the buyer should weigh a complete system on sale against an in-tier system at its regular list price.
How to match the bar 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 55-inch TV, a bar around 40 inches wide looks balanced, and a 65-inch or larger TV suits the wider bars in this guide, such as the wider LG and Vizio systems and the 40-inch Hisense bar. A small room also changes the bass: a large subwoofer in a small bedroom can overwhelm dialogue, so the dialogue modes on the Samsung and Sony bars and the night modes on the Samsung models 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.
Most picks in this guide use HDMI eARC, with one exception: the Samsung HW-B750D uses standard HDMI ARC, which fits its Dolby Digital 5.1 and DTS Virtual:X formats. Optical carries Dolby Digital 5.1 and stereo, but it cannot carry Dolby Atmos at all. The Vizio M51a-H6 adds a separate HDMI input, so a console or streaming box can connect through the bar without giving up a TV port.
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 soundbars under 400 dollars?
Yes, and this tier is where real Atmos stops being rare. The Hisense AX5140Q and the Vizio Elevate P514a-H6 both ship with up-firing height speakers, the JBL Bar 1000 has four up-firing drivers, and the Samsung HW-S60D and Sony HT-S2000 bring Atmos into a single bar.
The Vizio M51a-H6 is the exception to watch: it supports Dolby Atmos, but the effect is virtualised, with no up-firing drivers. 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 1000 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 Samsung HW-S60D or the Sony HT-S2000 is the smarter use of the budget.
What should you check before you buy a 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. Three 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 JBL Bar 1000 when it can be found in this tier, or the Hisense AX5140Q for a complete 5.1.4 system at its regular tier. If a tidy single bar matters more, the Samsung HW-S60D and the Sony HT-S2000 cover that need well. Measure your TV and room, check the HDMI connection, and confirm the new-package total before you order.
