The Amazon Fire TV Soundbar Plus is a 37-inch, 3.1-channel soundbar with a built-in subwoofer that connects to any TV with an HDMI port. Dolby Atmos and DTS:X spatial audio decoding are built in for surround content, along with a dedicated center channel that keeps dialogue clear on top of everything else in the mix. Preset sound modes for Movie, Music, Sport, and Night viewing tune the audio to match what’s on screen, and Bluetooth pairs with a phone to stream music.

A simple but full-featured soundbar that can make all your content sound better
The center channel is the reason to buy a 3.1 soundbar over a 2.0 model. A 2.0 setup splits every dialogue line between the left and right speakers, which works fine when voices are the only thing on screen but muddies them the second music or effects join in. The Soundbar Plus routes dialogue through its own dedicated driver, keeping voices distinct from everything else in the mix, which turns two hours of subtitles for muffled conversations back into two hours of just watching.
Behind the mesh grille on the front of the bar are eight drivers, arranged as three full-range speakers and three tweeters for the main channels, plus two internal subwoofer drivers for the low end. Each of the three main channels gets its own full-range and tweeter pair, and the internal subwoofer drivers add real bass punch without an external sub taking up floor space, though optional wireless subwoofer and surround speaker add-ons are available for a full 5.1 upgrade down the line.
