Sound bar

As sleek and stylish as today’s TVs are, there’s one aspect of their performance that you’ll almost certainly find disappointing: the sound. A roomful of home theater equipment is one solution. But there’s a much easier way to improve your TV sound: a sound bar speaker. 

Sound bars are perfect companions for flat-panel TVs. They don’t take up much space, and the wiring is simple. Most models have built-in amplification, and many come with wireless subwoofers for deep bass roar and rumble.  

Sound bars can sit in front of your TV or mount below it on the wall. Platform-style models sit beneath the TV. Now there are even curved models to match curved TV screens. Some come with Bluetooth® for wireless music playback from your smartphone.

Connection tips

If you have all your inputs connected to your TV, you won’t need a lot on your sound bar. Just make sure it has an audio input that matches one of the audio outputs on your TV — likely analog stereo RCA or optical digital outputs.

If you’ll be connecting components directly to your sound bar, you’ll want to be sure that your sound bar has enough audio inputs for everything you want to connect. Take a look at the graphics below for examples. And let’s not forget that some sound bars act like A/V receivers in their own right, offering video source switching.

Sometimes, you can mix your input strategies, connecting some components to your TV and some to your sound bar, but bear in mind things can get complicated in a hurry. Imagine your neighbor coming to your house to house-sit for a day or two. Does the note you leave start, “to watch a Blu-ray, set the TV to aux 1 and the sound bar to optical 2, but if you want to watch regular broadcast…”

That’s probably not why you bought a sound bar. Life is good when either your TV, or your sound bar has enough inputs for all the components you normally use, and then just ONE unit can be the boss. That’s when your notes to neighbors – and your lessons for how to operate the home theater in general – get simple. Consider a connection strategy based on one of the two concepts below.

Other inputs that may be available on sound bars are analog stereo minijacks, commonly used to accommodate the headphone outputs of smartphones and media players, and built-in Bluetooth® or Wi-Fi® receivers that can accept wireless streaming signals. More on these in a second.

Placement: Tabletop or wall-mounted?

Sound bar is too tall

Check your sound bar's height against your TV screen. If the sound bar is too tall, it can block a small portion of your TV picture or your TV's infrared sensor, which may prevent it from receiving remote control signals. Some sound bars have a built-in IR repeater or adjustable height to deal with this problem.

<strong>Check the sound bar footprint.</strong> Depending on the depth of the tabletop and the shape and size of the TV pedestal, the sound bar may not fit safely in front of your TV.

If you’ve placed your TV on a table or entertainment cabinet, setting the sound bar just in front of it seems like an obvious option. Many models come with special “feet” to make this easy.  But if you’d like to go that route, it’s worth taking a couple of quick measurements.

If you’d like to wall-mount your sound bar to match your TV, there are a couple of things to keep in mind. First, check your model to see if mounting brackets are included.  If not, be aware that not all sound bars, or included components, are wall-mountable. For example, a few sound bars are too deep to wall-mount – instead, they’re designed to sit on a tabletop, with your TV sitting directly on top of them. Also, included components such as subwoofers will not be wall-mountable. [Shop for a wall-mountable sound bar.]

Also, make sure there’s enough space below the wall-mounted TV to accommodate the sound bar without things looking crammed or cluttered. For example, if you’ve got an entertainment cabinet a few inches below your TV, you may have a tight fit.

If you do choose to mount your sound bar on the wall, remember your input choice, above. Will you need lots of wires leading to your sound bar? You’ll need to decide in advance how best to manage your cables. You'll have to run at least a signal cable, plus a power cable if the sound bar is amplified.

If you don't intend to run your cables through the wall, you can just let them hang down, or use a cable-hiding raceway to cover them. But if you do want to hide the wires in the wall, here are some important things to consider:

  • Try to avoid mounting your sound bar on an exterior wall, since these walls have extra bracing and insulation that can make running wire difficult.
  • Follow local building and fire codes. In many cases, this means you'll need to get UL-rated A/V cable labeled CL2 or CL3.
  • Don't run the power cable inside the wall. If you want the power cable hidden, you'll need to hire a licensed electrician to install a recessed AC receptacle in the wall, in a location where it will be covered by your sound bar or TV, and not obstructed by the sound bar's mounting bracket. You and your electrician may also want to consider in-wall power protection units. Another option is to route the A/V cable in-wall, and use a small wire raceway on the outside of your wall for the power cord.

You can find additional in-wall wiring tips and considerations in our detailed in-wall wiring guide.

Lastly, if your TV rests on a stand with too little room for a traditional sound bar, consider a platform-style unit. These models have all the functionality of a sound bar housed in a sturdy chassis you can rest your TV on. Be sure to check the weight and size of your TV along with the platform's specs to make sure it will support your TV.

Do you want a separate subwoofer?

If you plan to use your sound bar with your main HDTV, you’ll probably want a model with good bass response for higher-impact movies and TV shows. Many powered sound bars come with separate subwoofers for big, full-bodied bass. A few models that don’t come with subwoofers include subwoofer outputs so that you can add your own. An increasing number of sound bars now come with wireless subwoofers, so you don’t need to figure out how to run wires cleanly to its location. In fact, that location (within a reasonable radius of the main sound bar) can be anywhere in the room within reach of a power receptacle. [Shop for a powered sound bar with a separate subwoofer.]

On the other hand, if you’re buying a sound bar for a secondary viewing room, or if you don’t want the extra clutter of a subwoofer, you may prefer a model with built-in woofers for improved low-end. In general, these models won’t offer bass that’s as low or punchy has a separate subwoofer. But if room-shaking bass isn’t what you’re going for, these sound bars can be a great fit.

Amplification: Built-in or separate?

Most sound bars are powered – that is, they have the necessary amplification and signal processing built right in. These models are easy to set up, and offer more choices along the budget spectrum. [Shop for powered sound bars.] 

Other sound bars are passive – and essentially, they’re a specialized form of loudspeaker. They require an external amplifier for power. [Shop for passive sound bars.]

Sound optimization
A number of sound bars feature special audio processing to improve the listening experience. Look for a dialog enhancer for clear, easy-to-understand on-screen conversations. Or keep a lid on loud commercials by selecting output-leveling. These features may be called different things -- so be sure to check each product’s description for details.

If you want to hear special effects all around you – a car racing by on your right, or a thunderstorm filling the room – consider a sound bar with virtual surround sound. Many sound bars offer some form of virtual surround sound. Some just create a synthetic soundfield from 2 stereo channels; others decode a program’s original surround sound channels and use clever audio processing to trick your ears into thinking certain sound effects came from another direction. And some feature carefully aimed drivers that bounce sound off of surrounding walls to “bank-shot” the surround channels to your ears.

It’s important to think about which approach your sound bar may use – if it uses the wall-bounce option, an open-plan living space may not be the best placement for that class of sound bar.

On the other hand, if you just want a broader, more immersive front soundstage – clearer dialogue, with a wider, deeper sound field – then you may prefer a sound bar that plays two-channel stereo (front left and right) or three-channel sound (front left, center, front right).

Listen to music wirelessly with your smartphone

Sound bars are about more than just TV and movie sound. They're great for playing music too. Many sounds feature built-in Bluetooth — that makes it easy to stream music wirelessly from your smartphone or tablet. Listen to songs stored on your device or streamed from services like Pandora®, Spotify®, and even YouTube™. Some sound bars offer built-in Wi-Fi, for wireless music streaming over your home network.

Remote control options

Many sound bars with limited inputs either include a very basic remote with on/off, mute, and volume up/down commands, or don’t offer one at all.  Often these remotes can learn the same commands from your television's remote control.
