PLAYBASE Wireless Soundbase for Home Theater and Streaming Music

Your TV’s got the video part nailed. But the audio? That leaves a lot to be desired. Especially when it’s movie time. Game time. Music time. Come to think of it, any time.

The all new PLAYBASE adds pulse-pounding, full-theater sound to all your movies, TV shows, sports, and games – and it wirelessly streams your favorite music, too. Its slim, low profile design practically vanishes beneath your TV, yet it fills your entire viewing room with spectacular widescreen sound you just can’t miss. 

It is part of Sonos, the wireless Home Sound System that fills as many rooms as you want with great-sounding tunes. It’s a new, better way to fill each day with the sounds you love.


  • TV sound and music you can feel, from a speaker you’ll barely see.
  • Two-in-one. Adds full-theater sound for your TV. Streams music, too.
  • Simple two-cord setup. One for power. One for your TV.
  • Works with your existing TV remote.
  • Syncs wirelessly with SUB and two PLAY:1s for 5.1 surround sound.
  • Design that disappears under your TV. Sound you just can’t miss.

Movies and Music to the Power of 10

PLAYBASE uses ten amplified internal drivers–six midrange, three tweeters, and one woofer–to replace the steady drip of your TV's built-in speakers with deep booms, crystal clear whispers, and huge waves of sound.

An Off-the-Wall Approach to Better TV Sound

Conventional soundbars work best when wall-mounted directly below your TV. Problem is, most TVs aren’t on walls. They’re standing on credenzas and tabletops. PLAYBASE to the rescue. Its elegant, low profile design practically disappears beneath your TV, yet it fills your entire viewing room with sound that’s flat out amazing. 

Trueplay, Custom Speaker-Tuning for Your PLAYBASE

Trueplay bounces sound off various surfaces in your TV room, analyzing the distance from each wall, the location of your PLAYBASE, and the spot you love to watch from. Then it adjusts each woofer and tweeter to make sure perfectly-tuned sound reaches your ears from every direction at just the right instant and volume.

Never Obsolete

Software updates mean the product you buy today will be even better tomorrow.

One App. Complete Music Control

The Sonos app helps you quickly search through all your services to track down favorite music, send it to different rooms, and adjust the volume and other settings. You don’t even have to be in the same room. And if your friends have the Sonos app, they can do the same.

Over 30 Music Streaming Services Available

Sonos plays everything – the most popular streaming services, on-demand Internet radio, your favorite podcasts and audiobooks, your go-to collection of downloads – whatever you love to listen to.

Dialog Enhancement

Having a hard time hearing what’s being said? PLAYBASE uses custom drivers to deliver crisp, clear dialog to the center channel where your ears can best discern it. Need even more clarity? Turn on Speech Enhancement to keep the dialog at a consistent level and reduce the volume of any loud sound effects.

Night Mode

Watching late at night and don’t want to disturb the rest of the house? Turn on Night Sound. At lower volumes, quiet sounds are enhanced and the intensity of loud sounds is reduced.

Two Cords. That’s It. 

One power cord and one optical cord that connects to your TV. You don’t even have to read a manual because the Sonos app guides you through every step of the setup process, including connecting PLAYBASE to your Wi-Fi so you can stream your favorite music.

Plays Everything

Cable boxes. Gaming consoles. Satellite boxes. Blu-ray players. If it’s connected to your TV, PLAYBASE will play it.

Widescreen Sound - No Wall Mount Required

PLAYBASE securely supports TVs up to 75 lbs, which covers just about any TV that comes with its own stand.

Expand Beyond the TV Room

PLAYBASE makes movies, sports, TV, games, and music come alive… but just in one room. Add more Sonos speakers to your home and you can listen to what’s playing on your TV in any room.

Grows to 5.1 with Zero Drama

PLAYBASE is just the beginning of the ultimate home theater experience. Add a Sonos SUB for soul-shaking bass. Want full surround sound? Use a pair of PLAY:1, PLAY:3, or PLAY:5 speakers for rear channels.

One Less Remote to Worry About

PLAYBASE works with almost all TV, cable box, and universal remotes by learning their infrared (IR) commands during setup. The remotes you have are all you need


SUB Wireless Subwoofer

The refreshed SUB Wireless Subwoofer pushes the look of Sonos forward, bringing it in line with the PLAY:5. Its silver inner ring shifts to pure black, the Sonos logo is a little different, but the refreshed SUB inside is the same as before. It delivers the same bone-shaking bass with no buzz or rattle, and pairs with Sonos systems at the touch of a button.


  • Fills any room with deep, clear Hi-Fi sound
  • Wireless, one-button setup
  • Seamlessly integrates with the Sonos system
  • Two force-cancelling speakers positioned face-to-face offer deep sound with zero cabinet buzz or rattle
  • Place it anywhere in the room—even lying flat under a couch

Listen Down Deep

Fills an entire room with thick layers of deep, bottomless sound that let you hear and feel every chord, kick, splash, and roll. You won’t just hear the difference the wireless subwoofer makes—you’ll feel it in your bones.

All Sound, Zero Vibration

Two force-cancelling speakers positioned face-to-face means all the sound and energy from the music comes through loud and clear, and none of it is lost in cabinet buzz or rattle.

One-Button Setup

No wiring. No programming. Press one button, follow the simple prompts on your controller, and the system automatically adjusts audio settings to perfectly balance the sub and the paired Sonos component for a flawlessly optimized, whole-room listening experience.

Wherever You Want It

Because it’s wireless and designed to perform perfectly, whether positioned horizontally or vertically, you can put the SUB anywhere you want in the room — even lying flat under a couch.

Awesome Sonos Product
I was looking at Sonos for a while. I finally pulled the trigger. I don’t regret it. Great sound.

Great for funky room shapes
We needed a solution for a room few walls, lots of windows where there are walls, and sits above a loud AC unit. If you want to stop pushing volume up/volume down when the action scenes turn to whisper talk and back, and your room has some oddities, this does the trick. It surpassed my expectation. Bonus that the setup could not possibly be easier, and it works with Alexa.
