Dolby Atmos Overhead & All Around
Arc Ultra and the Era 300 surrounds fire up and out, sending Dolby Atmos content to the height and side channels that actually exist in the mix.
Stream Dolby Atmos Music with select songs from supported services. Experience Dolby Atmos home theater content with a compatible TV and HDMI eARC or HDMI ARC connection.
Bass You Feel In Your Ribs
Sub 4 takes over the lowest frequencies so Arc Ultra can focus on dialogue and detail. Explosions rumble in your chest. Basslines pulse through the floor.
Set It Up Where You Want
Place Sub 4 anywhere in the room, even under your sofa. It connects to Arc Ultra over WiFi, so you can create the setup that works best for your space.
Trueplay™ Tunes for the Room
Trueplay measures the acoustics of your room – walls, floors, furniture – and tunes your whole setup for the best sound.
The Hardest Part Is Picking the Movie
Plug it in, open the Sonos app, and the system handles setup from there. It even connects to your TV remote.
It's Not Just for TV
Music, podcasts, audiobooks, live radio. Play it all from the Sonos app. Apple AirPlay 2 and Bluetooth work too. Sonos Radio streams free from the moment you set it up.
Play & Control Hands-Free
Ask Sonos Voice Control to play music, turn it up, and more. Amazon Alexa is built-in, if you'd rather.
One System Connecting Every Room
Add Sonos anywhere in the house to grow your system. Play the same thing in every room, or something different in each.
