You want deep rumble during action scenes without spending a fortune. A budget soundbar with a subwoofer can transform your TV’s thin, hollow sound into something you actually feel — but the wrong pick leaves you with muddy dialogue and a sub that cuts out when you turn it up.
I’m Rikta — the founder and writer behind FitlyFast. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

$139.00$159.99as of Jul 15, 2:47 PMHow To Choose The Best Budget Soundbar With Subwoofer
You came here for one reason: a soundbar that includes a subwoofer for under. The mistake most shoppers make is chasing the highest peak wattage number, but a 240W spec means nothing if the subwoofer cuts out or the dialogue sounds like it’s underwater. Here is what actually matters.
Wireless vs. Wired Subwoofer
A wireless subwoofer sits anywhere in the room without a cable running to the soundbar, which makes placement simple. The catch is that wireless connections can occasionally drop or need a re-sync. A wired subwoofer is more stable because it uses a physical cable, but that cable limits where you can place the sub and often requires careful routing around furniture.
HDMI ARC Is the Key to Simplicity
HDMI ARC (Audio Return Channel — a special HDMI port that sends sound from your TV to the soundbar and also carries control signals) lets you control the soundbar’s volume with your existing TV remote. You plug one cable into the TV’s ARC-labeled HDMI port and never touch a second remote. Without ARC, you will use the soundbar’s own remote for volume, which gets annoying fast. Every soundbar in this guide offers HDMI ARC, but check that your TV has an ARC port — not all HDMI ports are the same.
Peak Power and Real-World Volume
Peak power (like 240W or 190W) is the maximum the system can hit in short bursts, not what it delivers continuously. A 100W system in a small to medium room can sound plenty loud, while a 240W system fills a larger living room. Focus on reviews that mention volume levels and room size rather than the wattage number alone.

In‑Depth Reviews
1. ULTIMEA Poseidon M30 Sound Bar with Wireless Subwoofer
$69.99$99.99as of Jul 15, 2:47 PMThe most power you can get at this price with app-based EQ control.
This 2.1-channel system delivers 240W of peak power — at 240W peak versus the Saiyin’s 100W peak, meaning significantly louder maximum output for larger rooms. The wireless subwoofer connects without audio cables, so you can place it anywhere. VoiceMX technology (a DSP feature that boosts vocal frequencies between 120 Hz and 6 kHz) keeps dialogue clear even during loud action scenes. Reviewers confirm that the ARC connection delivers “amazing, movie-theater-like sound” and that the subwoofer is impressive and clear.
The Ultimea App gives you a 10-band equalizer with 121 preset EQ matrices, which is a level of customization you normally see on soundbars costing twice as much. Buyers mention that the app is easier to use than the remote, and that the soundbar is very loud — filling a 15×20-foot room at half volume. The weak point is treble and high-frequency detail, which some users say feels lacking even after adjustments. One owner reported that the Game EQ setting worked best for music but didn’t stick between power cycles.
Unlike the TCL S55H which focuses on room calibration and Dolby Atmos, the ULTIMEA M30 is about raw power and detailed EQ control. If you want to tweak every frequency band and can live with slightly rolled-off highs, this is the one.
ULTIMEA deep bass
- 240W peak power is the highest in this lineup, filling larger rooms easily
- 10-band EQ with 121 presets via the Ultimea App offers deep customization
- VoiceMX technology keeps dialogue clear by boosting vocal frequencies dynamically
harsh highs
- Treble and high-frequency detail are weak even with maximum adjustment
- Game EQ mode doesn’t save between power cycles
- Soundbar is slightly shorter than the advertised dimensions
bass lovers: You want the most volume and EQ control for your dollar and you’re okay with average high-frequency performance.
treble sensitive: You need crisp treble for music or you want a soundbar that sounds great without needing app-based tuning.
2. TCL S55H 2.1 Sound Bar with Wireless Subwoofer
$139.00$159.99as of Jul 15, 2:47 PMThe one that brings Dolby Atmos without the premium price tag.
This system delivers cinematic audio with Dolby Atmos and DTS Virtual:X — two sound formats (Dolby Atmos creates overhead-like height effects; DTS Virtual:X widens the soundstage) that are rare at this price. The wireless subwoofer delivers deep, room-filling bass, and the AI Sonic Auto Room Calibration adjusts audio to your room’s layout through the TCL app. That means the sound balances itself for your specific couch position and wall placement, not a generic factory setting.
Buyers report that the app calibration improved speech clarity noticeably — one reviewer noted dialogue became clearer even with hearing aids — and the subwoofer added richness that makes explosions feel real. The subwoofer pairs automatically with the soundbar during setup. Buyers with Samsung TVs report that the bass remote didn’t always work perfectly, and one buyer mentioned the subwoofer needed a daily re-sync. At 220W peak power (220 watts of maximum short-burst output), it fills a 15×25-foot room comfortably, which matches the size of a typical living room.
Unlike the ULTIMEA Poseidon M30’s 240W peak, the TCL S55H focuses on sound processing (AI calibration and spatial audio) rather than raw wattage. You get a more refined, adaptive sound that works with your room instead of just blasting louder.
TCL balanced bass
- Dolby Atmos and DTS Virtual:X for a wider, more rich soundstage
- AI Sonic Auto Room Calibration tailors sound to your room’s layout via the TCL app
- Wireless subwoofer delivers deep bass that connects automatically during setup
limited surround
- Some Samsung TV owners mention bass remote compatibility issues
- A few buyers needed to re-sync the subwoofer daily
- Bass is subtle rather than thunderous; adds depth but won’t rattle walls
budget pick: You want adaptive room-calibrated sound with Dolby Atmos in a small to medium room and don’t mind occasional sub re-sync.
skip for movies: You need wall-shaking bass from the subwoofer or your setup demands a perfectly stable wireless connection every time.
3. Saiyin Detachable Sound Bar for Smart TV with Subwoofer
$89.99as of Jul 15, 2:47 PMThe only soundbar that turns into two tower speakers for a wider stage.
This 2-in-1 detachable design uses a speaker base to split the soundbar into two separate tower speakers, creating exceptional channel separation and a wider stereo soundstage. That means you get left and right channels physically apart, which sounds like instruments and voices come from distinct positions rather than a single box. The horn tweeters push sound further across the room, making this a strong choice for larger living areas. Under the hood, two silk dome tweeters and two custom 53mm x 83mm square woofers handle the audio.
Customers note impressive sound quality with strong bass that “vibrates the floor.” One customer observed that the port noise between 70-110Hz was fixed by adding foam in the port, which is a simple DIY tweak. The detachable speakers improve clarity and soundstage compared to a fixed bar. The unit has 10 levels of adjustable bass via the remote, though there is no on-screen indicator for the bass level. At 100W peak power, it’s 100W compared to the ULTIMEA M30’s 240W peak, but reviewers point out it still sounds rich and clear. The 5-year after-sales warranty and free lifetime accessory replacements add confidence.
Unlike the TCL S55H which uses a wireless sub, the Saiyin subwoofer connects via a wired cable for stable, uninterrupted bass. The trade-off is that the sub placement is limited by cable length.
Saiyin modular design
- Detachable design splits into two tower speakers for a noticeably wider soundstage
- Silk dome tweeters deliver clear, detailed high frequencies
- 5-year warranty and free lifetime accessory replacements
weak center
- 100W peak power is not ideal for very large rooms
- Port noise between 70-110Hz may require a DIY foam fix
- No on-screen indicator for bass level makes adjustments feel blind
flexible setup: Anyone who values a wide stereo soundstage and wants the flexibility to use the speakers as towers or a single bar.
skip for clarity: You need high maximum volume for a large room or you don’t want to deal with a wired subwoofer placement.
4. INFITBO D40-4M 2.1CH Sound Bar with Subwoofer
$84.14$98.99Ends inas of Jul 15, 2:47 PMThe soundbar designed for PC users who also want a home theater.
This is the only system in the lineup that connects directly to your PC or laptop via USB for digital audio without needing a separate sound card. The 5.25-inch wired subwoofer has a 12L cavity, which means a larger internal air volume for deeper bass. At 190W peak power, it sits between the 240W ULTIMEA and the 100W Saiyin in raw output. The soundbar splits into two separate tower speakers for a wider stereo field, similar to the Saiyin, or stays as one unit under your TV.
Buyers praise the “excellent bass that adds depth to music and movies” and note that the wired connection means no disconnection issues — unlike their previous JBL 3.1 which dropped signal. The slim design (just over 2 inches tall) won’t block your TV’s IR sensor. However, the system does not support Dolby Audio, and buyers mention the power cord is short, which may require a DC power extender for wall-mounted setups. One reviewer deducted a star for the cord length but called the sound great and the price competitive.
Unlike the TCL S55H which focuses on wireless convenience and Dolby Atmos, the INFITBO is built for stability — every connection between the soundbar segments and subwoofer is wired. You lose flexibility in placement but gain rock-solid signal reliability.
INFTBO compact power
- Direct USB audio from PC without needing a sound card
- 5.25-inch wired subwoofer with a large 12L cavity for deep bass
- Detachable design works as a soundbar or separate L/R speakers
muddy mids
- Does not support Dolby Audio
- Short power cord may require an extension for wall-mounting
- Cables between segments and subwoofer limit placement options
small rooms: You want a versatile system for both PC gaming and TV, and you prefer the stability of wired connections over wireless.
not for music: You need Dolby Atmos or DTS support, or you want a fully wireless subwoofer for flexible room placement.
5. Assistrust KY-8000E Sound Bar with Subwoofer
$79.89$93.99Limited time dealas of Jul 15, 2:47 PMFour placement options give you total control over your sound layout.
This system offers four physical setups — standing tabletop, wall mount, horizontal tabletop, and wall-mount split — each with a different sound profile. Standing tabletop gives stereo sound with clear voices for daily streaming, while wall-mount split mode delivers balanced mids and bright highs for the living room. The wired subwoofer adds stereo depth to music, and the 110W peak power (60W from the soundbar) is enough for small to medium rooms. Three EQ modes (Movie, Music, News) are pre-tuned, so you don’t need to adjust bass or treble manually.
Buyers love that the soundbar splits into two standing speakers for “excellent sound” and that the subwoofer adds deep bass. One user highlighted that the ARC mode failed initially because of a wrong cable, but support quickly sent the correct ARC cable. Another reviewer praised the sound quality for songs and movies and the easy bass adjustment. The remote is a weak point — shoppers say the sound field button cycles between loud blaring voice and normal, and the voice mode button has unclear effects. The system is backed by an 18-month warranty.
Unlike the INFITBO which prioritizes PC connectivity, the Assistrust KY-8000E is about placement flexibility and simplicity. You get four distinct setup options to match your room, but the limited remote and lack of app control mean you rely on those pre-tuned EQ modes
Assistrust loud output
- Four placement options with different sound profiles for different rooms
- Pre-tuned EQ modes mean no manual bass/treble adjustments needed
- Detachable design splits into two standing speakers for wider sound
basic features
- Remote is finicky — sound field and voice mode buttons behave oddly
- 110W peak power is lower than many competitors; best for small rooms
- No app support for EQ customization
party use: Buyers who want maximum placement flexibility and prefer simple pre-tuned modes over fiddling with an app.
skip for detail: Anyone who needs high maximum volume for a large room or wants reliable remote control functionality.
6. LG S40T 2.1 ch. Soundbar with Wireless Subwoofer
$169.99$229.99as of Jul 15, 2:47 PMThe natural partner for LG TV owners who want one-remote simplicity.
The WOW Interface lets you control the soundbar and your LG TV with a single remote — you adjust volume, check connection status, and select sound modes right on the TV screen. This integration saves you from juggling two remotes. The wireless subwoofer delivers booming bass that adds punch to movies and games, and the LG Soundbar App gives you a 3-band equalizer (bass, treble, mid-range) to fine-tune the sound from your phone. Dolby Audio compatibility ensures enhanced sound quality for all your content.
Buyers with LG TVs call the installation easy and the sound “significantly better” than their Sony TV’s built-in speakerbar. One reviewer with a 7-year-old Samsung said the connection was easy and that cinema mode provided perfect sound. The crest design uses a metal grill that keeps dust out. However, a reviewer who switched from Bose found this soundbar disappointing — the bass wasn’t loud enough and dialogue seemed off. The unit has no bottom or rear mounting holes, which limits wall-mounting options.
Unlike the TCL S55H which uses AI room calibration for any TV brand, the LG S40T’s best features (WOW Interface, single-remote control) are locked to LG TVs. Outside that ecosystem, you lose the key advantage that makes this soundbar special.
LG clear dialogue
- WOW Interface lets you control the soundbar from your LG TV remote with on-screen menus
- Dolby Audio compatibility delivers enhanced sound for movies and shows
- LG Soundbar App offers a 3-band EQ for quick customization
weak subwoofer
- Best features are exclusive to LG TVs; limited value with other brands
- No bottom or rear mounting holes limit wall-mounting options
- Bass and dialogue clarity fall short compared to premium brands like Bose
TV upgrade: You own an LG TV and want smooth single-remote control with decent sound.
bass heads: You use a Samsung, Sony, or other brand TV, or you need deep bass that matches a Bose-level experience.
7. LARKSOUND 2.1 CH Sound Bar with Subwoofer
$69.99as of Jul 15, 2:47 PMThe most affordable way to add a subwoofer to your TV setup.
This entry-level system pairs a 31-inch soundbar with a wired subwoofer that measures 6.7 x 5.9 x 13.0 inches, making it compact enough to fit under most TVs. The slim design (2.36 inches tall) slides under your TV without blocking the screen. Four EQ modes — Music, Movie, Voice, and Normal — let you switch presets for different content. The Night Mode cuts volume by 50% instantly, helpful for late-night viewing without disturbing others.
Buyers report “excellent sound and great bass for the price” and that the system outperforms expectations for a 2.1 setup with no distortion. The HDMI ARC connection works reliably, turning the soundbar on and off with the TV. The subwoofer adds good bass that can be adjusted down. However, one shopper added a critical flaw: the subwoofer “cuts out when turned up,” which is disappointing for bass lovers. Another reviewer reported sound cutting out suddenly after initial good performance. The remote is lightweight plastic with limited functionality, and the Bluetooth 5.0 maxes out at a 33-foot range.
Unlike the top-tier TCL S55H with its AI calibration and wireless sub, the LARKSOUND is the literal entry point — you get a subwoofer and basic features for the lowest price. The risk is the subwoofer cutting out at higher volumes, which the ULTIMEA M30’s 240W wireless sub handles without issue.
LARKSOUND value
- Lowest entry price for a complete 2.1 system with a dedicated subwoofer
- Night Mode instantly reduces volume by 50% for late-night watching
- Slim 31-inch design fits neatly under most TVs without blocking the screen
tinny sound
- Subwoofer cuts out when volume is turned up, per multiple buyer reports
- Bluetooth 5.0 is older and offers a shorter 33-foot range
- Remote is lightweight plastic with limited functionality
tight budget: Budget-constrained buyers who want the cheapest possible 2.1 system and watch at moderate volumes.
skip for quality: You like your action movies loud, because the subwoofer cuts out when pushed beyond moderate levels.
Understanding the Specs
HDMI ARC
HDMI ARC (Audio Return Channel) is a special HDMI port that sends sound from your TV to the soundbar and also carries control signals. When you connect a soundbar via HDMI ARC, your TV remote can adjust the soundbar volume and even turn it on/off with the TV. This eliminates the need for a second remote. All soundbars in this guide support HDMI ARC, but your TV must have an ARC-labeled HDMI port — check before buying.
Peak Power vs RMS Power
Peak power (like 240W) is the maximum the system can output in short bursts during loud passages like explosions. It is not what the system runs at continuously. RMS (Root Mean Square) power is the continuous output you actually hear. Most budget soundbars list peak power because it is a higher, more impressive number. A 100W peak system can still sound great in a small room, while a 240W peak system gives you headroom for larger spaces without distortion.
Wired vs Wireless Subwoofer
A wireless subwoofer connects to the soundbar via a radio signal instead of an audio cable. This gives you freedom to place the sub anywhere in the room — behind a couch, in a corner, or across the room — without tripping over a cable. The trade-off is that wireless signals can occasionally drop or need re-syncing. A wired subwoofer uses a physical audio cable, which ensures a rock-solid, interference-free connection but limits placement options to within cable reach of the soundbar.
Detachable 2-in-1 Design
Some soundbars, like the Saiyin and Assistrust models, split into two separate speaker towers that you place on either side of your TV. This creates a wider stereo soundstage — you hear distinct left and right channels rather than sound coming from one central box. The effect is similar to having two separate speakers, which improves clarity and spatial awareness in movies and music. When joined together, they function as a standard single soundbar.

Final Thoughts: The Verdict
For most people, the best budget soundbar with subwoofer overall is the TCL S55H because it combines Dolby Atmos and DTS Virtual:X with AI room calibration at a price that undercuts everything with those features. If you want maximum raw power and app-based EQ control, grab the ULTIMEA Poseidon M30. For the widest stereo soundstage, the Saiyin detachable soundbar turns into two tower speakers that outperform its price bracket. And if you’re on the tightest budget, the LARKSOUND 2.1 CH gets you a subwoofer and soundbar for the lowest entry cost.
