You don't need a soundbar, but your TV's built-in speakers probably disappoint you

Most smart TVs come with speakers built into the back or bottom of the frame. These speakers are small, face away from you, and are designed to meet a minimum standard—not to sound good. A soundbar is not required to watch television. But if you've noticed that dialogue is hard to hear, action scenes sound thin, or you turn the volume up and still feel like something is missing, a soundbar addresses all three problems at once.

The real question is whether the trade-off makes sense for your room and your budget. A soundbar costs between $100 and $800 depending on features. It takes up shelf space or wall space. It adds another device to your setup. But it also transforms how movies, shows, and sports sound—often more noticeably than upgrading your TV itself.

Key Takeaways

  • Smart TV speakers are designed to be small and cheap, not to reproduce dialogue clearly or bass at any volume.
  • A soundbar improves dialogue clarity, adds bass, and fills a room with sound in ways a TV speaker cannot, regardless of the TV's size or price.
  • You need a soundbar only if poor sound bothers you enough to justify the cost and the extra device in your setup.
  • Budget soundbars ($100–$250) solve the dialogue and bass problem; expensive ones add surround sound and wireless subwoofers that TV speakers cannot match.
  • Placement matters: a soundbar mounted above or below the TV works better than one on a shelf to the side, and a clear path between the soundbar and your seating area prevents muffled sound.

Why TV speakers fail at the most important job

Smart TVs have gotten thinner and lighter, but speakers have not gotten better—they've gotten worse. A TV speaker is typically a small rectangle of plastic with a driver (the part that actually vibrates to make sound) roughly the size of a postage stamp. It sits inside the TV frame, often facing downward or backward, which means sound bounces off your furniture before it reaches your ears.

The result is that dialogue—the thing you actually need to hear—comes out thin and muffled. Bass, if it exists at all, is felt as a rattle rather than a rumble. Volume goes up, but clarity does not. You end up turning subtitles on for shows you should be able to understand without them.

A soundbar solves this by putting a larger speaker directly between the TV and your ears, facing you. The speaker is wider, so it can move more air. It sits at ear level or above, so sound travels straight to you instead of bouncing around the room first. This is why even a $150 soundbar usually sounds dramatically better than a $3,000 TV's built-in speakers.

When you probably don't need one

If you watch mostly news, talk shows, or sports, and you can hear the dialogue clearly at a comfortable volume, your TV speakers are doing their job well enough. Some people genuinely do not notice bad sound, or they watch in rooms where they cannot add another device. A soundbar is not a necessity in those cases.

You also do not need a soundbar if you already have a home theater system—a receiver with separate speakers in different parts of the room. That setup will always sound better than a soundbar because it spreads sound across multiple locations and can create surround effects. A soundbar is a shortcut for people who want better sound without the complexity of a full system.

What a soundbar actually gives you at different price points

Budget soundbars ($100–$250) have one or two drivers and no separate subwoofer. They improve dialogue clarity dramatically because the speaker is larger and faces you directly. Bass is better than a TV speaker but not deep—you feel it more than you hear it. These work well for apartments, bedrooms, or rooms where you cannot add a subwoofer.

Mid-range soundbars ($250–$500) often come with a wireless subwoofer included or sold separately. The subwoofer is a box that sits on the floor and handles low frequencies, so bass sounds like bass instead of a rumble. These soundbars may also have side-firing drivers that bounce sound off walls to create a wider soundstage. They work well for living rooms and larger spaces.

Premium soundbars ($500–$800+) add more drivers, better electronics, and sometimes wireless rear speakers that sit behind your seating area. These create a surround-sound effect similar to a home theater system. They are worth the cost only if you watch movies regularly and have the space and budget for the full setup.

How to know if a soundbar will actually fit your space

Measure the width of your TV stand or the wall space where you plan to mount the soundbar. Most soundbars are between 28 and 65 inches wide. A soundbar should not hang over the edges of your TV stand—it looks awkward and can fall. If your TV is on a small stand, you may need a soundbar narrower than the TV itself, or you may need to mount it on the wall above the TV instead.

Check whether you have a clear path between the soundbar and where you sit. If a soundbar sits inside a cabinet or behind a closed door, sound will be muffled. If it sits on a shelf with a wall directly behind it, bass will bounce backward instead of forward. The best placement is on an open shelf below the TV or mounted on the wall above it, with nothing blocking the front.

If you want a subwoofer, measure the floor space where it will sit. A subwoofer is typically a cube between 12 and 18 inches on each side. It needs to sit on the floor, not on a shelf—bass frequencies travel through the floor and walls, so placement matters more than you might think. A corner of the room usually works well.

Connection and setup are simpler than they sound

Most soundbars connect to your TV through a single cable—usually HDMI or optical audio. HDMI is simpler because it carries both picture and sound, and many soundbars can control your TV's volume with your soundbar remote. Optical audio is older but still common and works reliably. Both are plug-and-play; you do not need to understand audio settings to make them work.

Wireless subwoofers pair to the soundbar automatically when you turn them on for the first time. You do not need to run cables across your room. If the soundbar has rear speakers, they pair the same way. Setup usually takes 10 to 15 minutes and involves plugging in the soundbar, connecting it to your TV, and turning everything on.

Some soundbars also have Bluetooth, which lets you play music from your phone without connecting to the TV. This is convenient but not necessary for watching television.

The real cost of adding a soundbar to your setup

Beyond the purchase price, a soundbar takes up physical space. If your TV sits on a stand, the soundbar goes on the shelf below it or mounts on the wall. If your TV is wall-mounted, the soundbar mounts below it. Either way, it is visible and takes up room. Some people find this acceptable; others prefer the clean look of a TV with nothing in front of it.

A soundbar also adds another device to your setup. It needs power, a cable to your TV, and possibly a remote. If you already have a cable box, streaming device, and game console, adding a soundbar means one more thing to manage. This is a minor inconvenience for most people but worth considering if you prefer simplicity.

The last cost is maintenance. Soundbars rarely break, but they do collect dust and may need occasional cleaning. If you buy one with a subwoofer, you have two devices to manage instead of one. Again, this is minor, but it is not zero.

Frequently Asked Questions

Will a soundbar work with any smart TV?

Yes. Any soundbar connects to any TV through HDMI or optical audio. You do not need the soundbar and TV to be the same brand. The only exception is if your TV has no audio output—extremely rare on modern TVs, but worth checking your TV's manual if you have an unusual model.

Can I use a soundbar without a subwoofer?

Yes. Budget and mid-range soundbars work fine on their own. A subwoofer adds bass depth, but it is not required. If you watch mostly dialogue-heavy content like news or shows, you may not notice the difference. If you watch movies or sports, a subwoofer makes a noticeable improvement.

What if my TV is mounted on the wall with no space below it?

Mount the soundbar on the wall directly below the TV, or above it if that looks better in your space. Wall mounting is straightforward and usually comes with a bracket in the box. Make sure the soundbar is at ear level or slightly above when you are sitting down.

Do I need a soundbar if I have a smart TV with good reviews?

TV reviews focus on picture quality, not sound. Even expensive TVs with excellent screens have mediocre speakers. If you have not heard the TV's sound in person, you cannot know whether it will bother you. If dialogue is already hard to hear, a soundbar will help regardless of the TV's price or rating.

How long do soundbars last?

Most soundbars last 5 to 10 years with normal use. They have no moving parts except the speaker drivers, which are durable. The most common failure is a power supply issue, which is rare. Soundbars are more reliable than TVs in most cases.
