• The ultimate Dolby Atmos experience: The lateral and overhead channels in Arc Ultra and both Era 300 speakers immerse you an an all-encompassing spatial audio soundstage. You’ll hear planes as if they’re flying above, sense footsteps moving across the room, and feel like you're inside your music.

• Feel the bass: Experience every rumble, roar, and beat you've been missing with clean, pulse-pounding bass. Sub 4 takes over the lowest frequencies so paired speakers are free to focus on midrange and high frequencies so everything sounds even clearer.

• Wonderfully wireless: Place Sub 4 anywhere in the room, even under your sofa. It connects to the soundbar over WiFi, so you can create the setup that works best for your space.

• Perfectly tuned for the room: Using the microphones in your iOS device, Trueplay tuning technology analyzes the unique acoustics of your space and optimizes the EQ. So all your content sounds just the way it should.

• Breeze through setup: Simply plug in the power cable, connect your phone or tablet to WiFi, and open the Sonos app. It will guide you through connecting the soundbar to your TV and syncing your TV remote for streamlined control.

• Stream everything you love: Play music, podcasts, and audiobooks from all your favorite services over WiFi using the Sonos app, Apple AirPlay 2, and more. Enjoy access to free music, original content, and thousands of live stations as soon as you get set up.

• Use your voice: Play music and control your system with hands-free ease and unmatched privacy using Sonos Voice Control. Ask Amazon Alexa to answer your questions, manage compatible smart home devices, and more.
