Start with your TV size and room layout

The soundbar you need depends mostly on how far you sit from your TV and how big the room is. A soundbar designed for a 55-inch TV in a living room will sound thin and weak in a basement home theater, and an expensive cinema soundbar will be overkill for a bedroom. Measure the distance from your couch to the TV — if it's under 8 feet, a compact 2.0 or 2.1 soundbar (two channels plus optional subwoofer) will do the job. If it's 10 feet or more, look at 3.1 or 5.1 systems (three front channels plus subwoofer, or full surround).

The room's shape and materials matter too. A carpeted, furnished living room absorbs sound and needs less power than a hard-floored, empty basement. Hard surfaces bounce sound around and can make dialogue muddy, so you may want a soundbar with a center channel that's straightforward to adjust. If your TV is mounted on a wall, you can wall-mount most soundbars directly below it. If your TV sits on a stand or console, make sure the soundbar will fit in front of it without blocking the screen or vents.

Key Takeaways

  • Soundbars under 8 feet from your seating need only 2.0 or 2.1 channels; rooms 10 feet or larger benefit from 3.1 or 5.1 setups.
  • Dialogue clarity matters more than bass for most viewers, so test how a soundbar handles speech before you buy.
  • HDMI eARC or optical audio is the easiest connection method; Bluetooth works but can add delay and drop the connection.
  • A subwoofer adds cost but is not required unless you watch action movies regularly or have a large room.
  • Most soundbars need a power outlet nearby, so check the cable length and whether your setup has space for the power brick.

Dialogue clarity is more important than bass

The most common complaint about soundbars is that dialogue becomes hard to understand, especially in TV shows and news broadcasts. This happens when the center channel — the speaker that handles most speech — is weak or poorly tuned. Before you buy, watch a scene with dialogue on the soundbar's demo model or read reviews that specifically mention how clear speech sounds. If a review says "dialogue is crisp" or "voices cut through," that's a good sign. If it says "you'll need to turn on subtitles" or "dialogue gets lost in action scenes," skip it.

Bass is the second priority. A soundbar without a subwoofer can still sound good for TV and streaming, but it will lack the low-end punch of explosions and music. If you watch mostly dramas, news, and comedies, you don't need a subwoofer. If you watch action films, sports, or play video games regularly, a subwoofer will make a real difference. Many soundbars come with a subwoofer included; others let you add one later. Adding a subwoofer later usually costs between $150 and $400, depending on the brand.

Connection type affects ease of setup and reliability

HDMI eARC is the best connection method if your TV supports it (most TVs made after 2016 do). You plug the soundbar into the eARC port on your TV with a single HDMI cable, and the TV sends audio to the soundbar automatically. No separate audio cables needed, and the connection is stable. Check your TV's manual to find which HDMI port is the eARC port — it's usually port 3 or 4, not port 1.

Optical audio is the second choice. You run a thin optical cable from your TV's optical audio output to the soundbar's optical input. It's reliable and works on almost all TVs, even older ones. The cable costs $5 to $15 and is straightforward to replace if it breaks.

Bluetooth is convenient for playing music from your phone but not ideal for TV. Bluetooth can add a delay of 100 to 200 milliseconds, which means the sound arrives after the actor's lips move. For TV, use HDMI eARC or optical. Bluetooth is fine as a backup option.

AUX (3.5mm jack) is rarely used on modern soundbars but appears on some budget models. It works but offers no volume control from your TV remote, so you'll have to adjust the soundbar itself every time.

Decide whether you need a subwoofer now or later

A subwoofer is a separate speaker that handles bass frequencies below 100 Hz. It sits on the floor, usually to the side of your TV or in a corner. A good subwoofer costs $150 to $300 and makes action movies, sports, and music sound fuller and more immersive. For TV shows, news, and streaming dramas, it's optional.

Some soundbars come with a subwoofer included in the package. Others are sold without one, but the manufacturer makes a matching subwoofer you can buy separately. A few budget soundbars don't offer a subwoofer option at all. If you think you might want one later, buy a soundbar from a brand that sells subwoofers — Sonos, Samsung, LG, and Bose all do. Mixing a subwoofer from a different brand usually doesn't work well because the sound won't match.

If you're unsure, start without a subwoofer. You can always add one in six months if you feel like the bass is missing. Most people who buy a soundbar without a subwoofer are happy with it.

Check the physical fit in your space

Measure the width of your TV stand or the wall space below your TV. Most soundbars range from 28 inches to 65 inches wide. A soundbar that's wider than your TV stand will overhang on both sides, which is usually fine — just make sure it doesn't block your TV's vents or tip over. If your TV stand is narrow, look for a compact soundbar under 40 inches wide.

Check the depth too. A soundbar typically sticks out 3 to 5 inches from the wall. If your TV is mounted close to a wall or you have a narrow console, make sure there's enough clearance. Also confirm that the power cable is long enough to reach an outlet. Most soundbars come with a 6-foot power cable; if your nearest outlet is farther away, you'll need an extension cord.

If you're buying a subwoofer, plan where it will go. Subwoofers are usually 12 to 18 inches tall and 12 to 16 inches wide. A corner placement works well because it reinforces bass, but any spot on the floor near your seating area will work. Make sure there's a power outlet nearby.

Compare features that matter versus features that don't

Features that matter: Adjustable treble and bass controls let you tune the sound to your room. A remote control with dedicated volume buttons makes daily use easier. Support for Dolby Atmos (a surround-sound format) is useful if you watch movies on streaming services or Blu-ray, though it's not essential for TV. A night mode or dialogue boost feature helps if you watch late at night or have hearing loss.

Features that don't matter much: Voice control (Alexa, Google Assistant) is convenient but not necessary — your TV remote already controls volume. Built-in WiFi is useful for multi-room audio if you own other speakers from the same brand, but it's not required. Bluetooth 5.0 versus 4.2 makes no practical difference for soundbars. LED displays are nice to look at but don't affect sound quality.

Read reviews from people who own the soundbar, not just tech reviewers. Look for comments about how it sounds after three months of use, whether the remote batteries die quickly, and whether customer service is responsive if something breaks. A soundbar that sounds great in a store demo but has poor reviews for reliability is a bad deal.

Budget ranges and what you get at each level

Soundbars under $150 are compact, work well in small rooms, and handle dialogue clearly. They usually have basic controls and limited bass. Brands like TCL, Insignia, and Vizio make solid budget models. These are good if you have a small bedroom or don't watch many action movies.

Soundbars from $150 to $300 offer better build quality, more adjustable settings, and optional subwoofers. Brands like Samsung, LG, and Sonos have popular models in this range. This is the sweet spot for most living rooms.

Soundbars over $300 add premium materials, more surround channels, and better customer support. They sound noticeably better in large rooms or if you're sensitive to audio quality. Bose, Sonos, and high-end Samsung models are in this category. Unless you're an audio enthusiast or have a very large room, you won't hear a meaningful difference compared to a $250 soundbar.

Test before you buy if possible

If you're buying in a store, ask to hear a demo. Listen to a scene with dialogue, then a scene with action or music. Does the speech sound natural? Can you hear the bass? Is the volume loud enough without distortion? Many stores let you return a soundbar within 14 to 30 days if you're not happy, so check the return policy before you leave.

If you're buying online, read reviews from verified buyers who mention specific TV shows or movies they watched. A review that says "great for sports" or "dialogue is clear on Netflix" is more useful than a generic five-star rating. Look for reviews that mention the room size — a review from someone with a small bedroom may not explore to your large living room.

Frequently Asked Questions

Do I need a soundbar if my TV already has speakers?

TV speakers are usually thin and tinny because there's no room for real drivers inside the TV. A soundbar, even a budget one, will sound noticeably better for dialogue and music. If you watch TV more than a few hours a week, a soundbar is worth it.

Can I use a soundbar with a receiver and surround speakers?

Yes, but it's usually not necessary. A soundbar with a subwoofer handles most TV and streaming content well. A full 5.1 or 7.1 system with a receiver, surround speakers, and a subwoofer is better for movies and gaming but costs much more and requires more setup. Start with a soundbar; upgrade later if you want.

What if my TV doesn't have eARC or optical audio?

Older TVs sometimes lack both. In that case, Bluetooth is your only option, though it may add a slight delay. You can also use an HDMI audio extractor (a small device that converts HDMI to optical), which costs $20 to $40 and works with any TV.

Will a soundbar work with my gaming console?

Yes. Connect the soundbar to your TV the same way you would for regular TV, and the console's audio will play through the soundbar. If your console supports Dolby Atmos, a soundbar with Atmos support will sound better, but it's not required.

How long do soundbars last?

A good soundbar lasts 5 to 10 years with normal use. The most common failure is a remote battery contact issue or a power supply problem, both of which are usually fixable. Speakers themselves rarely fail unless the soundbar is damaged or exposed to moisture.
