How to Choose a Soundbar for Your TV: What Actually Matters

by Simon | Oct 20, 2026 | Soundbars

To choose a soundbar for your TV, start with the problem you want to fix: hard-to-hear dialogue, weak bass, or sound that never seems to leave the screen. Then check your TV's audio connections and the space available around it. Those decisions will narrow your choices faster than a wattage rating or a long list of audio logos.

For everyday viewing, put clear speech, easy volume control, and a sensible physical fit first. For movie nights, add a subwoofer and consider separate surround speakers. Dolby Atmos deserves a closer look once those basics are covered.

How To Choose A Soundbar For Your TV

Start With What You Want to Hear Better

A soundbar for the evening news has a different job from a system bought for action movies. Use your main complaint to decide where the money should go.

Your PriorityWhat to Look For
Clearer dialogueGood speech reproduction at normal volume, useful dialogue controls, and preferably an adjustable center channel.
More impact in moviesA capable subwoofer, with separate surrounds if you want effects beside or behind the couch.
Bedroom or apartment useClear sound at low volume, adjustable bass, and a practical night mode.
GamingSuitable audio-format support, low audible delay, and the right HDMI signal path.
Music as well as TVBalanced stereo playback and support for the streaming methods you actually use.

Check Your TV's Connections Before You Buy

Look at the labels beside the TV's ports or check its manual. An ordinary HDMI input isn't enough for sending TV audio back to a soundbar: you need a port marked ARC or eARC.

ConnectionWhat It Means for Your Purchase
HDMI eARCThe most flexible TV audio return connection here. It can carry high-bandwidth formats such as Dolby TrueHD and multichannel PCM when both devices support them.
HDMI ARCSuitable for many everyday setups. Dolby Digital Plus Atmos can work over ARC, but support depends on the TV, source, and soundbar.
OpticalA useful option for older TVs. It can carry stereo PCM and compatible compressed surround formats such as Dolby Digital 5.1, but not Dolby Atmos.

HDMI-CEC can let your TV remote handle the soundbar's volume and power. Check support on both devices; optical doesn't carry CEC control.

As HDMI's eARC overview explains, eARC expands the audio formats the connection can transport. It doesn't mean every eARC soundbar can decode every format. Check the soundbar's supported formats and the TV's passthrough support separately, especially for DTS-based disc soundtracks.

Check Your TV Connections Before Buying A Soundbar

Put Dialogue Clarity Ahead of Extra Bass

If you keep reaching for subtitles, listen to speech before judging explosions. A dedicated center channel can help anchor dialogue to the screen, and a separate center-level adjustment gives you a useful way to raise voices without turning everything up.

Still, a center speaker isn't a guarantee of clear sound. Tuning, placement, the soundtrack, and the room all matter. A good stereo soundbar can be easier to understand than a poorly balanced model with more channels.

Look for dialogue enhancement you can switch on and off. Try it with a quiet conversation and then a busy scene with music underneath. Keep it enabled if words become easier to follow without voices turning thin or harsh.

A useful listening test: turn the volume down to your usual late-night level. If speech only becomes intelligible when the whole system gets loud, it may not solve the problem you bought it for.

Understand 2.1, 3.1, 5.1, and Atmos Channel Numbers

Channel numbers describe the audio layout a soundbar system offers. They don't tell you how natural voices sound, how deep the bass goes, or how well it performs in your room.

  • 2.0: left and right channels, without a separate subwoofer channel.
  • 2.1: left and right channels plus a subwoofer channel.
  • 3.1: left, center, and right channels plus a subwoofer channel.
  • 5.1: five main channels, including surround channels, plus a subwoofer channel.
  • 5.1.2: five main channels, a subwoofer channel, and two height channels.

Check how those channels are produced. A soundbar may use separate rear speakers, side-firing drivers, or processing to create its surround presentation. A “5.1” label alone doesn't tell you whether speakers for the back of the room are included.

Read the package contents and speaker layout together. Also check whether the bass hardware is built into the bar or supplied as a separate box.

Decide Whether Dolby Atmos Fits Your Room

Dolby Atmos can add a sense of height and movement to compatible soundtracks. Soundbars deliver that experience in different ways: some have upward-firing drivers that reflect sound off the ceiling, while others use virtualization without dedicated upward-firing speakers.

For a model with up-firing drivers, placement matters. Leave the top unobstructed and check the manufacturer's ceiling and seating guidance. A high or sloped ceiling can make reflected height effects less predictable. A bar tucked under a shelf can't use the room in the same way as one with a clear path above it.

Dolby's speaker setup guide explains the role of height speakers and placement. Treat Atmos support as a capability to investigate, rather than a rating of sound quality.

If you're choosing between a basic Atmos bar and a well-reviewed non-Atmos system with clearer dialogue or included surrounds, prioritize the improvement you want most.

Measure the Space Below Your TV

TV screen size doesn't dictate soundbar size. A compact bar can work with a large screen in a small room; a wider bar still needs to fit the furniture and have room around its drivers.

Measure the available width, height, and depth in inches. Check the distance between the TV's feet, clearance below the picture, and access to the TV's remote sensor. Leave space for cable plugs behind the bar.

Place it near the front of the cabinet, following the manufacturer's clearance instructions. Avoid enclosing side-firing or upward-firing drivers inside furniture. For wall mounting, check the required bracket and clearance before ordering.

If you're wall-mounting the screen, work out how high to mount your TV with the soundbar and its required clearance included.

Consider the listening space, too. A couch eight feet away in an enclosed room is a different demand from seating fifteen feet away in an open living area. Look for independent reviews that discuss clean output at your likely listening distance, rather than choosing by advertised watts.

Choose Between a Single Bar, a Subwoofer, and Rear Speakers

A Separate Subwoofer Adds Low-End Weight

A subwoofer handles low bass: the rumble of an engine, the weight of a drum, or the impact underneath an action scene. It makes sense if those are the things your TV sound is missing.

Check for independent subwoofer-level control. In an apartment, you'll want enough adjustment to enjoy fuller sound without making bass dominate the room. A night mode may help, but it doesn't stop bass from traveling to neighbors.

Don't assume the only available corner is the best position. Try a few permitted locations and listen from the couch for uneven or boomy bass.

Soundbar With Subwoofer And Rear Speakers

Separate Surround Speakers Put Sound Around the Seating Area

If your goal is to hear effects beside or behind you, a package with physically separate surrounds is worth shortlisting. It gives those sounds speakers near the listening area, although placement and the soundtrack still determine the result.

Check the wiring diagram. “Wireless” often describes the audio connection to the bar: the speakers may still need outlets, or wires to a powered receiver module. Some designs use rechargeable speakers instead.

Check expansion before buying: optional subwoofers and rear speakers usually have model-specific compatibility. Being from the same brand isn't enough. Confirm the exact accessory models and their combined cost.

Check the Signal Path for Gaming and Streaming

With a console connected directly to the TV, video goes to the screen and audio returns to the soundbar over ARC or eARC. This can preserve the TV's gaming features without asking the soundbar to pass the video through. The TV must still pass the audio format you want.

If you connect the console to a soundbar's HDMI input instead, the bar must pass the required video features to the TV. Verify 4K at 120Hz, VRR, and the HDR formats you use individually. An eARC port doesn't promise any of those video capabilities, and some soundbars have no separate HDMI inputs.

Atmos delivery also varies by source. Sonos documents that devices such as Apple TV can use Dolby MAT, which requires eARC when routed through the TV to its compatible soundbars. Don't assume that Atmos working in a built-in TV app proves it will work through every external player.

Our guide to using a streaming device with a smart TV can help you decide which source you'll actually use. Check that source's audio requirements before choosing the bar.

Set a Budget for the Complete System

Compare the price of everything you intend to use. A standalone bar and a package containing a subwoofer and rear speakers aren't equivalent purchases, even when the main units cost the same.

With a $500 spending limit, a bar that uses the whole budget leaves no room for stands or optional speakers. Include any required mounts, cables, and planned additions before deciding which system you can afford.

For one bar-and-subwoofer package to compare, see our TCL S55H offer and confirm the current price before deciding.

Spend according to your priorities:

  • Everyday TV: favor speech clarity, reliable remote control, and straightforward operation.
  • Movies: compare complete subwoofer and surround packages before committing to a bar with expensive optional accessories.
  • Music: check the exact Wi-Fi streaming services and protocols supported. Wi-Fi on the specification sheet doesn't confirm every music feature.

Check whether setup or room correction requires an app, an account, or a particular phone. Automatic room correction can help adjust the system to its surroundings, but it can't remove the limitations of a blocked driver or an awkward speaker position.

If music is your main use and you have space either side of the TV, compare powered stereo speakers or an amplifier-and-speaker setup as well. For a more extensive theater system, an AV receiver with separate speakers is another option; allow for its extra space, wiring, and setup.

Test It With Your Own Shows Before the Return Window Closes

A store demo can show scale and impact. It won't tell you how comfortably you can follow your favorite drama at home.

Buy with a return policy you understand, keep the packaging, and try these checks early:

  1. Play a familiar conversation. Listen at normal and low volume, with dialogue enhancement both on and off.
  2. Try a demanding movie scene. Check whether voices remain understandable when the music and effects build.
  3. Sit in the other seats. Make sure family members don't lose too much clarity away from the center.
  4. Use your actual sources. Test TV apps, your streaming player, and your console where relevant.
  5. Check everyday operation. Try volume control, standby, input changes, and lip sync.
  6. Confirm the incoming format. Use the soundbar's app or display, if available, to check what it receives.

If dialogue doesn't match the actors' lips, try our soundbar lip sync fixes before deciding the new bar needs to go back.

Start with the manufacturer's recommended setup and run room correction if provided. Change one setting at a time so you can tell whether it helps. Don't assume the loudest demo mode is the right everyday setting.

Our Recommendation

For everyday TV, start with a soundbar that delivers understandable speech at your usual volume, fits below the screen, and works conveniently with your TV remote. Favor eARC when both devices support it and you want flexibility for higher-bandwidth audio. An older TV with optical can still support a useful, simpler upgrade.

For movies, decide whether you're willing to place a subwoofer and surround speakers before paying for a premium standalone bar. Compare complete systems at the same total cost. Add Atmos to the shortlist when compatible content, speaker placement, and your room give you a practical way to use it.

Frequently Asked Questions

Does a soundbar have to match the TV brand?

No. Match the connections and supported audio formats. Features that combine TV speakers with a soundbar, or provide extra on-screen controls, may require specific compatible models from the same brand.

Can I keep using my TV speakers with a soundbar?

Only use them together if your equipment supports a coordinated mode for that purpose. Simply enabling both outputs can create an echo or timing mismatch. Otherwise, select the soundbar as the TV's audio output.

Do I need a new HDMI cable for eARC?

Try the supplied cable or a suitable existing cable first, following both devices' instructions. If replacing it, a certified Ultra High Speed HDMI cable is a straightforward choice. Paying more for an expensive cable won't improve sound once the digital connection works correctly.

Can I use Bluetooth instead of HDMI or optical?

If both devices support Bluetooth TV audio, you may be able to. Check compatibility and lip sync. For a main TV setup, choose HDMI ARC/eARC or optical first; Bluetooth support for music doesn't establish the same TV-audio capabilities.
