Specs compared

How we chose these

We started with a pool of nine 2.1 channel soundbars, all with a separate subwoofer, that matched the channel requirement. We then compared each model's stated specifications: object-based audio support, HDMI ARC availability, Bluetooth version, and power output. No soundbar was tested; we relied on the manufacturer's published details and the catalogue listing. Prices are live and read from the store listing at the time shown. Every pick is included because the pool held fewer than twelve entries.

What to look for

Channels: what 2.1 actually means

A 2.1 channel soundbar has two audio channels (left and right) plus a subwoofer that handles bass. That third number, .1, refers to a dedicated home theater subwoofer channel. In this list, every pick is 2.1 and includes a separate subwoofer, meaning you get a fuller low end than a soundbar without a sub. The left and right channels are where dialogue and effects come from, so a good 2.1 soundbar can improve TV dialogue and music even without rear speakers.

Object-based audio: Dolby Atmos and DTS:X

Dolby Atmos and DTS:X are object-based audio formats that add height information, but they don't require extra physical speakers in a soundbar. They create a virtual surround effect that can make sound feel more immersive. In this pool, only the TCL S55H and the Westinghouse support both formats. If you watch a lot of Blu-rays or streaming content with these formats, choose one of those two. Otherwise, the more common Dolby Audio or DTS Virtual:X are still upgrades over standard TV speakers.

Connections: HDMI ARC and Bluetooth

HDMI ARC (Audio Return Channel) is a feature that lets your TV send audio to the soundbar and also control its volume with your TV remote. It's convenient, but it's not standard on every soundbar. Only the Hisense HS2100 and Westinghouse in this list advertise HDMI ARC. Bluetooth is more common, but version matters. The Hisense uses Bluetooth 5.3, which is the newest version in this group. Bluetooth versions like 5.0 and 5.1 are fine for audio, but a newer version can offer better power efficiency and more stable connections. Check your TV's ports before buying.

Power and subwoofer size

Power specifications differ among the 2.1 soundbars here. The JBL Bar 2.1 Deep Bass lists a maximum output of 300W, while the TCL S55H lists 220W. The Westinghouse lists 120W RMS, which is a root-mean-square measurement and reflects a different figure than peak power. A larger subwoofer driver can also affect bass response: the JBL uses a 6.5 inch driver, the largest stated size in this list. For small rooms, a lower-wattage model may be sufficient; for larger spaces, consider a higher-wattage option.

Voice clarity and adaptive modes

Dialogue can be hard to hear on many TVs. Some soundbars offer specific voice enhancement modes: the Samsung HW-B550F has Voice Enhance Mode, and the Samsung HW-B550/ZA has Adaptive Sound Lite. The LG S40T has AI Sound Pro, which tries to optimize audio for content. These features are worth looking for if you often struggle with speech intelligibility. If you watch a lot of news or sports, a voice mode can be a major convenience. Without those, you may need to adjust the treble manually, if the soundbar offers such control.

Hearing safety at high volumes

Soundbars can produce loud volumes, and prolonged exposure to high sound pressure levels can damage your hearing. The National Institute on Deafness and Other Communication Disorders notes that sounds at or above 85 dBA can cause hearing loss after long or repeated exposure. When using any of these soundbars, keep the volume at a moderate level, especially for movies with loud effects. Many soundbars have a night mode or auto volume that can reduce sudden loud peaks. If you have children, consider choosing a soundbar with a limiter or just set the volume level carefully.

Questions

Do I need a 2.1 soundbar for a small TV?

Yes, a 2.1 soundbar is often enough for a small to medium-sized room. The subwoofer provides the low end that TV speakers lack, while the two front channels handle dialogue and main effects. If your TV is in a bedroom or office, a 2.1 setup is a compact upgrade. For a large living room with high ceilings, you might want more channels or an external subwoofer, but 2.1 can still work well.

Is there a big difference between Dolby Atmos and DTS:X on a soundbar?

Both are object-based formats that create a virtual height effect without requiring physical height speakers. In a soundbar, the difference is subtle, but both can widen the soundstage. The TCL S55H and Westinghouse both support both formats, so you won't lose compatibility with either kind of content. If you only care about one format, check which one your streaming service or movies use.

What is the advantage of HDMI ARC over Bluetooth?

HDMI ARC lets your TV control the soundbar with one remote and can pass through high-quality audio formats from TV apps. Bluetooth can introduce a small delay and sometimes compresses audio. If your TV has an HDMI ARC port, using it will give you better control and potentially better audio quality. The Hisense and Westinghouse models in this list include HDMI ARC, so you can use that connection instead of Bluetooth.

Can a 2.1 soundbar be used for music?

Yes, a 2.1 soundbar is fine for music, especially if you connect via Bluetooth to your phone. The subwoofer gives music more body, and the front channels handle vocals and instruments. Some models, like the JBL Bar 2.1 Deep Bass, have large subwoofers that can make music feel more powerful. If you are a serious music listener, you may want to look for a soundbar with a dedicated music mode, but all of the picks here will play music clearly.

Do I need to buy extra cables for these soundbars?

Most soundbars include the necessary cables for basic connection: an optical cable, an HDMI cable, or a power cable. But the specific contents vary by model. If you connect via Bluetooth, you don't need a cable at all for audio. If you use HDMI ARC, you may need an HDMI cable if it isn't included.
