Setting up the Arc Ultra is easy, with a single HDMI connection and step-by-step app-based instruction. Additional features provide clear dialogue, music streaming, private listening, and more.
Sound Motion
Sonos' new Sound Motion technology consists of a four-motor, dual-membrane woofer that is crafted to deliver exceptional bass in a flat, compact design. This technology works with the seven angled tweeters, two up-firing tweeters, six mid-woofers, and Dolby Atmos support for a truly immersive surround sound experience.
Personal Surround Sound
For owners of the Sonos Ace headphones, enjoy a more personal listening experience without disturbing others by activating TV Audio Swap. With the press of a button, TV Audio Swap will send the audio from the Arc Ultra to your headphones. You can still listen discretely without Sonos Ace headphones by activating Night Sound. Night Sound both reduces the intensity of loud sounds and enhances the quieter ones.
Ultra-Clear Dialogue
Arc Ultra is engineered to make dialogue understandable, so you can finally hear what actors have to say without constantly raising the volume or turning on subtitles. If you need even more clarity, select your desired level of Speech Enhancement within the Sonos app.
Streaming Music
Use your Arc Ultra for more than just movies and TV. Stream your favorite music from a home network Wi-Fi connection, a mobile device over Bluetooth, or via Apple AirPlay 2 and Spotify Connect.
Trueplay and Voice Control
A built-in far-field microphone array uses both beamforming technology and multi-channel echo cancellation to provide accurate voice control and Trueplay tuning. Trueplay is available for both iOS and Android devices, using this mic array to customize the Arc Ultra's EQ settings to better match the audio output to your specific room's acoustics.
Multiple Control Options
You can operate the Sonos Arc Ultra is a wide variety of ways. You can use your existing TV remote, the Sonos mobile app, built-in touch controls, Sonos Voice Control, or Amazon Alexa.
Additional Features
Enjoy privacy by using a single switch to turn off the mic array

Sonos Sub 4 Wireless Subwoofer (White)
Breathe new life into your movies, TV shows, and music when you add the Sonos Sub 4 Wireless Subwoofer to your existing compatible Sonos soundbar or speaker. This 4th generation white-colored Sonos Sub features a matte finish and works with many existing Sonos speakers, such as the Arc and Arc Ultra, Beam, Sonos Five, Era 100, and Era 300. Setup is a breeze, requiring only a power cable connection and the Sonos mobile app. The subwoofer pairs to other speakers wireless via dual-band Wi-Fi 4 (802.11n). Delivering this increased immersion and pulse-pounding bass are two 5 x 8" elliptical woofers. They face inward in a force-cancelling configuration to virtually eliminate distortion, leaving you with rumbling bass frequencies as low as 25 Hz.
Trueplay
The Sonos Sub 4 is compatible with Trueplay technology, which automatically adjusts the audio settings of the Sub 4 to better match the acoustic qualities of your listening space.
Stand Up or Lie Down
You have the option of standing the Sub 4 upright or laying it down on its side, which allows you to slide it under a couch or TV stand to keep it out of view.
Additional Features
With the purchase of a second Sub 4, you can pair both to maximize immersion

After Replacing The BEAM 2 With The Arc Ultra, I Finally Realized How Good Of A Soundbar The Beam 2 Is. We Use Both Sound Systems With SONOS Symfonisk Rear Speakers, And I Bought The Arc Ultra To (hopefully) Get A More Realistic And Not Virtual Atmos Effect.
Even Dialed All The Way Up To 10, I Found The Height Effect To Be Mweh. Mind You, This Is After Running Trueplay, And Running Tests Playing The Usual Atmos Demo Videos. Our Ceilings Are Average Height And Are Perfectly Horizontal, So The Sound Should Bounce Off Nicely. But I Wasn't Blown Away, Especially After All The Hype Created By The Countless Reviews I Watched Before Spending So Much Money.
The Same Can Be Said About The Purported Improved Bass Response. I Know There's This Revolutionary Dutch Technology Involved, But Again, I Wasn't That Impressed. Audiophiles Will No Doubt Tell Me I Should Invest In A Subwoofer And Two Era 300's To Meet My Expectations. But If You're Like Me And You Are On A Limited Budget, You Try To Buy The Best You Can Based On What You Can Afford.
Don't Get Me Wrong, The Ultra Is A Good Sounding Soundbar. The Dialogue Is Clear, The Soundstage Is Wider, And It Will Fill Your Room If You Let It. But, Especially If You Already Have A SONOS System In Place, It Is Not Plug And Play. I Had To Unpair And Repair My Rear Speakers Before My New Soundbar Would Work In Unison Which Nobody Had Told Me. Now That Everything Is Connected, I Am Enjoying My Home Theater Setup, But It's Not The Big Step Up In Sound Quality I Had Dreamt Of.
As Always, B & H Was Brilliant. Fast Delivery. Good Price. Great Service.

The Sonos Arc Ultra Soundbar (Black), B&H # SOARCULTBLK, can be connected to a standard HDMI ARC port, but Dolby Atmos audio is only supported with a full eARC connection. If this soundbar is connected to a standard ARC port, then the audio output will be limited to a 5.1-channel configuration.
