- Top Pick: 2.0 ch 100W Sound Bar for Smart TV, 2-in-1 Detachable Bluetooth 5.3 Speaker with 3 EQ Modes & Adjustable Bass – Home Theater Audio for Movies, Gaming, Music
- Best Value: TOVZAIX Sound Bar, 100W Sound Bar for Smart TV with Bluetooth 5.3/ARC/Opt/AUX, 2-in-1 Detachable Home Soundbar, 3 Equalizer Modes, Surround Sound & Bass Effect, TV Speaker for TV/PC/Gaming/Projectors
- Premium Choice: TCL S45H 2.0 Sound Bar for Smart TV | Dolby Atmos DTS:X Auto Room Calibration| 100W Power Wireless Bluetooth Home Theater Audio | App & Remote Control | Latest Model
Shopping for soundbars under 100 dollars is a different game from shopping for a premium home theater. At this level, no single model does everything, so the useful question is which compromise bothers you least: weaker bass, fewer inputs, a smaller soundstage, or an unfamiliar brand. Most of the bars below promise “100W,” which is a power figure on the box rather than a measure of sound quality. Read it as a label, not a promise.
This guide is for anyone replacing thin built-in TV speakers in 2026, from a dorm room to a bedroom to a gaming desk with a monitor on it. Judgments come only from the listing titles: channel layout, connections, format support, and whether a subwoofer is included. Because current figures move, confirm that each model still fits under 100 dollars before you order. A premium-tier bar and a desktop PC speaker also appeared in the source list, and both were left out because they do not match what a budget TV soundbar is for.

How to Choose
Subwoofer or no subwoofer
A bar with no subwoofer, such as a 2.0 model, is the easiest to place but the weakest on bass. A bar with a separate subwoofer, either wired or wireless, gives low frequencies room to breathe, in exchange for an extra box and a power outlet. In a small room, a 2.0 bar often suffices. In a living room with a sofa several feet from the TV, a subwoofer-equipped set is the safer way to cover the low end.
Connections you will use every day
HDMI ARC is the simplest link on modern TVs: one cable, and the TV remote can control volume. Optical works on older sets but carries fewer formats. AUX covers odd cases like a laptop or old console. Bluetooth is for music from a phone. Count the ports your TV has, because a bar whose input does not match your TV is a bar you will return.
Reading format claims at this tier
“Dolby Atmos” on a 2.0 or 2.1 bar means the bar can accept or process the signal, not that it has speakers pointing at the ceiling. Only a bar with physical height drivers creates overhead sound. At this tier, treat Atmos as a compatibility feature and focus on whether dialogue is clear and bass is controllable.
What to ignore and where budget models cut corners
Ignore peak watt figures and lighting modes when judging sound. Budget models tend to save on enclosure quality, the subwoofer, and the amount of equalizer control. Also be aware that several listings use generic brand names, so firmware updates, replacement parts, and support may be limited. Buy from a seller with a clear return window.
The 8 Best Options
2.0ch 100W Detachable Bar
A 2.0 channel bar whose listing highlights a 2-in-1 design: the unit detaches into a Bluetooth speaker. Three EQ modes and adjustable bass are named, and the title points to movies, gaming, and music. It suits a buyer who wants one product for the TV and for background music in another room, such as a kitchen or a patio table. Bluetooth 5.3 is the version named, so pairing with a recent phone is straightforward.
- Strength: a detachable portable speaker adds a second use.
- Strength: three EQ modes and adjustable bass allow some tuning.
- Trade-off: the title names no brand and no subwoofer, so bass depth is likely limited.
Skip it if you want a recognizable brand or strong low-end effects.
TOVZAIX 100W Sound Bar
A detachable 2-in-1 soundbar with Bluetooth 5.3, ARC, optical, and AUX inputs, three equalizer modes, and a surround and bass effect. The title also names TVs, PCs, gaming, and projectors, which makes it the most flexible input set among the 2.0 bars. A student with a TV, a laptop, and an old console could connect all three without buying adapters, which is the real appeal of a long port list at this tier.
- Strength: four connection types cover TVs, projectors, and PCs.
- Strength: Bluetooth 5.3 is listed for music.
- Trade-off: the title lists no rear speakers, so any surround effect comes from processing.
Skip it if you expect true surround or a bass-heavy sound from a bar with no subwoofer.
TCL S45H
A 2.0 bar from a TV maker, with a listed 100W power figure, Dolby Atmos, DTS:X, auto room calibration, Bluetooth, and a remote and app. It is the only bar here that pairs a known TV brand with format support and room calibration in the title. A buyer who dislikes guessing at equalizer settings may like having the calibration handled for them, and the remote and app add control from the sofa.
- Strength: Dolby Atmos and DTS:X decoding are both named.
- Strength: auto room calibration and an app are included.
- Trade-off: a 2.0 layout has no subwoofer, so low bass depends on the bar alone.
Skip it if bass impact matters most and you would rather have a separate subwoofer.
RGB 100W Detachable Bar
A 100W bar with three RGB lighting modes, Bluetooth 5.3, ARC, optical, and AUX inputs, a detachable 2-in-1 speaker, and three equalizer modes. The lights target gamers who want their desk or TV area to glow. Like the other detachable bars, it can split into a portable speaker, so one purchase serves a console corner and a bedside table.
- Strength: RGB lighting suits a gaming setup.
- Strength: it offers the same input variety as other detachable bars.
- Trade-off: lighting adds nothing to sound and may distract during movies.
Skip it if you prefer a plain look or care about audio over lighting.
GEOYEAO 2.1ch
A 2.1 channel set with a subwoofer, a listed 100W power figure, a Dolby Atmos surround claim, and Bluetooth, for TVs, projectors, and PCs. The separate subwoofer is the key difference from the 2.0 bars. For a living room where a thin bar sounds hollow, adding a dedicated bass unit is the simplest fix on this list, and the listing says the plural “subwoofers,” so confirm what ships in the box.
- Strength: a separate subwoofer handles low frequencies.
- Strength: use with TVs, projectors, and PCs is stated.
- Trade-off: the Atmos label on a 2.1 system is best read as format compatibility, not overhead speakers.
Skip it if you have no room for a subwoofer.
Saiyin Sound Bar
A subwoofer-equipped bar with a detachable design, a horn tweeter, adjustable bass, and HDMI-ARC, Bluetooth, optical, and AUX connections. The horn tweeter is a feature aimed at making speech and high notes more distinct. The combination of a subwoofer and four input types makes it a practical all-rounder for a bedroom TV that also gets a laptop or console hooked up now and then.
- Strength: HDMI-ARC and three other input types are named.
- Strength: adjustable bass helps tailor the sound to the room.
- Trade-off: it is a generic-brand product, so support depth is unclear.
Skip it if you want format support such as Atmos or a recognizable brand.
RIOWOIS 3.1ch
A 3.1 channel bar with a 5.25 inch wired subwoofer, a deep bass focus, and ARC, optical, AUX, and Bluetooth 5.3 connections. The center channel helps with dialogue, and the wired subwoofer avoids wireless pairing steps. Of the eight bars here it is the one with the most channels, which suits a viewer whose main complaint is that actors are hard to understand over music and effects.
- Strength: a 3.1 layout adds a center channel for speech.
- Strength: the 5.25 inch subwoofer is a named size.
- Trade-off: the subwoofer is wired, so placement is limited by cable length.
Skip it if you want a cable-free room.
BESTISAN 40 Inch Bar
A 40 inch bar with a listed 100 watt output, wired and wireless connections, Bluetooth 5.0, a DSP audio mode, adjustable bass, and wall mounting. It is a sensible fit under a mid-size wall-mounted TV, and the 40 inch length in the title helps you check width against your set before ordering. The 105dB figure in the title is a maximum-output claim, not a promise of clean sound.
- Strength: wall mountable, saving shelf space.
- Strength: both wired and wireless connection methods are listed.
- Trade-off: Bluetooth 5.0 is older than the 5.3 on most competitors here.
Skip it if you want the newest Bluetooth version or any Atmos support. Its strengths are the mounting option and the simple connections, not feature count.
Which One Fits Your Situation
You watch movies and want the best format support
Choose the TCL S45H. It names Dolby Atmos, DTS:X, and room calibration, which is a rare combination at this tier.
You want bass without a big investment
Pick the RIOWOIS 3.1ch or GEOYEAO 2.1ch, since both include a separate subwoofer. The RIOWOIS adds a center channel, the GEOYEAO adds a longer list of devices it can serve.
You game on a projector or a monitor
The RGB 100W Detachable Bar and the TOVZAIX both list projector and PC use, and the lighting on the first makes it the playful choice.
You need to mount it on the wall
The BESTISAN 40 Inch Bar is the one that lists wall mounting directly in its title.
Common Mistakes
- Reading “100W” as a measure of loudness or quality.
- Expecting a 2.0 bar to deliver deep bass without a subwoofer.
- Buying without checking the TV for an ARC, optical, or AUX output.
- Treating an Atmos label on a small bar as proof of overhead sound.
- Ignoring return windows on generic-brand products.
Frequently Asked Questions
Is a soundbar under 100 dollars worth it?
Usually yes, if your TV speakers sound thin or muddy. Even a basic bar can improve dialogue clarity, though it will not match a larger system.
Do I need a subwoofer?
Not in a small room, but it helps in a larger space. Models that include one give low frequencies more room.
What is the difference between ARC and optical?
ARC runs over HDMI and lets the TV remote control volume. Optical is a separate cable that works on older TVs but carries fewer audio formats.
Why do so many listings say 100W?
It is a common peak figure used to market bars at this tier. It does not describe how loud or clear the sound will actually be.
