Everything you need to know

What is a sound bar?

A sound bar, or soundbar, is a low-profile, all-in-one speaker system that’s designed to present stereo or surround sound in a small space. A sound bar is typically paired with a TV to provide a sonic experience that’s far superior to the weak sound produced by a TV’s tiny built-in speakers—but sound bars can also stream music (including Hi-Res Audio) and connect to devices such as Blu-Ray players and gaming consoles. Most of the time, a sound bar simply sits below your TV on an entertainment center, but sound bars can also be mounted on the wall below (or sometimes above) a TV.

Sound bars contain anywhere from two to seven or more speakers, and often incorporate drivers that angle outward from the sides or upward toward the ceiling to produce more immersive, room-filling sound, like Dolby Atmos.

How to choose a sound bar?

Choosing a sound bar is easier than you think. Start by determining the best size, something that runs about the same width as your TV and fits on furniture below your TV or on the wall. Then, think about the sonic experience you want. All sound bars have multiple speakers but channel configurations can vary, from 2-channel stereo sound bars to sound bars with center channels that emphasize dialogue to Dolby Atmos soundbars that combine eleven or more speakers to produce truly immersive Atmos or DTS:X sound.

Consider whether you prefer a minimalist sound bar-only setup or an expanded system that includes a subwoofer and surrounds for more immersive sound with deeper bass. Then, look at feature sets: Many sound bars provide virtual surround, bass-boost, and vocal-clarifying effects; Bluetooth or wi-fi streaming; and voice assistant integration.

Do I need a subwoofer with a sound bar?

Whether you need a subwoofer with a sound bar depends on your priorities. A sound bar doesn’t need a subwoofer to sound great—and any sound bar will greatly improve your TV sound—but by design, a subwoofer can produce lower frequencies than sound bar speakers can, which is why many sound bars are packaged with subwoofers. If you’re on a budget, you can still have a great audio experience without one. If you seek room-shaking bass that you can feel, a subwoofer is the way to go. The great news is you can always add one whenever you’re ready.

What is the best sound bar for Dolby Atmos?

The best sound bar for Dolby Atmos includes up-firing speakers, which fire sound at the ceiling where it reflects back toward the listener to provide the “height” element of the immersive Atmos experience. Our Signa S4 sound bar, for example, has a seven-speaker array with up-firing height speakers, and includes a subwoofer. Adding surrounds rounds out the 360-degree sound field for the truest immersion. If you don’t have the space or budget for a full-blown Atmos system, sound bars like our MagniFi   are incredibly effective at creating a virtual Atmos experience using digital processing.

Why buy a Polk sound bar?

Is a sound bar worth it?
