About the Polk Audio React System

Colin M.

Slim and powerful

The Polk React sound bar system delivers roomy, detailed sound from a low-profile design that easily fits under most TVs. Built-in Dolby® Digital and DTS® decoding lets this two-channel bar deliver virtual surround sound effects. This means you can enjoy compelling 3D sound without filling your house with speakers and running wire across the room.

Slim and powerful

The Polk React sound bar system delivers roomy, detailed sound from a low-profile design that easily fits under most TVs. Built-in Dolby® Digital and DTS® decoding lets this two-channel bar deliver virtual surround sound effects. This means you can enjoy compelling 3D sound without filling your house with speakers and running wire across the room.

Don't miss the quiet moments

Quiet conversations can sometimes get lost in the mix of a movie or game's soundtrack. We've all strained our ears at some point to catch important lines. Polk's Voice Adjust technology lets you quickly adjust voice levels to make sure you're consistently getting clear, intelligible dialogue.

Built-in Alexa

With Alexa built-in, you can control the sound bar using only your voice. Turn the volume up or down, change sound modes, and access streaming services like Amazon Music to play your favorite tunes. You can also ask Alexa to check the weather or snag recipes while you're cooking. If you set your phone up with the Alexa app and sync your contacts, you can even make calls and send messages through the sound bar. 

Amazon multi-room

Built-in Alexa gives you more than just voice control. It also lets you make this sound bar part of a wireless multi-room audio system, using additional Alexa devices (sold separately). You can group multiple Alexa devices to play the same music together. Or have each device play something else entirely in different parts of your house. Want to rock out to Metallica's "One" while you're working out in the garage, but the kids want to jam to "Can't Stop the Feeling" in the living room? No problem.

Easy to control

If you prefer hands-on to voice control, you can do that too. The sound bar includes a remote, but is also compatible with the vast majority of TV remotes currently on the market. No scrambling for the right remote — you can just use the one already in your hands.

The bar's preset sound modes also help you make quick adjustments with the press of a button. There's a preset for movies, music, and watching TV at night when the kids are down for the count.

Polk REACT Subwoofer 7" wireless powered subwoofer

The Polk React subwoofer is slim and wireless to make it easy to fill your room with sweet bass.

Bring the bass

The React subwoofer is included with this package to add impactful bass to your system. It's designed to work seamlessly with the sound bar, delivering low-frequency rumble that helps you feel your favorite movies and video games.

Simple setup

This subwoofer can be set up in a couple minutes, tops. Plug in the power, press a couple buttons, and it's go time. It's also wireless and compact, so it's not hard to find a nice spot for your sub. (You'll just need to plug it into an AC outlet.)

With Polk Adjust™ EQ, the sound bar even automatically adjusts its settings to account for the low frequencies being covered by the sub.

Product Research


Active Soundbar Speaker: The Polk React is a 2.0ch active soundbar speaker that consists of two 1" soft-dome tweeters, two 3.75" x 2.75" full-range drivers, and two 4.25" x 4" passive radiators for dynamic, room-filling sound. It supports Dolby Digital, DTS, and 2ch PCM playback. Optional Polk SR2 wireless rear speakers (sold separately) can be paired to the soundbar in order to create a true surround sound experience.

Wireless Powered Sub: The Polk React Sub has been perfectly tuned to extend the bass of the React soundbar for virtually any movie or music soundtrack. The React Sub wirelessly connects to a React soundbar speaker with a wireless range of approximately 30'. Once connected, Polk's Bass Adjust EQ automatically adjust the React Series soundbar settings to accommodate the React Sub's additional bass. The Polk React Sub houses a down-firing 7" long-throw, high-excursion woofer that is driven by a built-in amplifier for deep, extended bass. The wireless powered subwoofer's bass-reflex enclosure features a down-firing low-turbulence, flared port tube that keeps the bass tight and precise.

Note: Simply press the "Connect" button on the back of the soundbar and the sub to pair the two units together.

Listening Modes: Select Movie, Music, Sports, or Night mode to optimize the soundbar for your listening application. Movie mode provides a virtual "theater-like" surround sound, while Music mode is suitable for enjoying music in stereo.

Sports mode enhances dialog-rich content, like sporting events, news, casts, and talk shows.

Voice Adjust: Voice Adjust technology dramatically increases vocal clarity and volume level for crystal clear dialog no matter what you're watching.

Customer Q&A

1 question already asked

Can Alexa be disabled or turned off on this sound bar?
[ Thomas  Oct 20, 2022 ]
1 answer
Essentially yes, Tom. Even though Alexa is built-in on the Polk Audio React, you need to download the Alexa app to your smart device and set it up with the app for Alexa to work. If you do not ever do this, the Alexa is never activated. If you are already using the voice control features, you can simply open the app and delete the bar from the Alexa app, removing it from your Alexa network. I hope this helps Tom!
