Features

  • 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. Youll hear planes as if theyre 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.
  • Build your perfect sound system: Listen in any room, every room, and beyond. Put on a podcast in the kitchen, get immersed in a movie, or listen on the go with portable sound.

  • Great, Except for Apple Music on Apple TV
Color: Black
I ordered straight from Sonos. Received all the set, and setup was a breeze. Love the sound! But know this: I listen Dolby music through my Apple TV, and it does NOT handle it correctly. Main vocal is SO faint. I called and spent a long time in the phone. They ultimately told me to use the Sonos app instead of my Apple TV, but that doesn’t sound nearly as good as Dolby Sound. At this price point, I expect better. So, if you are an AppleTV user, know that some songs in Apple Music don’t sound right. ... show more

  • Finally Impressed with My Home Audio, I'm Not Easy to Please!
Color: Black
Wow! I have struggled for years to put together good home audio. I never really liked the sound of my music or tv shows/movies at home! My old receiver and speakers weren't great, my newest soundbars were just ok, I was never happy. I even recently tried the Sony Quads with SW5 sub. They did not work in my large space either! There was no center and they seemed weak. This Sonos package with Arc Ultra, Sub 4, and 2 Eras 300 is an absolute game changer! Atmos Music and Atmos shows/movies is out of this world. I am not easy to please! I was scared of the app, but I actually found setup easy and it's working fine. No need for an additional remote control! Just use the app and your TV remote! I love the bubble of sound this total package creates around me. Sure, the front separation could be better with a traditional receiver and speakers, but in Atmos content, the sound bar actually expands the soundstage pretty far beyond the bar, so with the biggest movies and shows, it's no issue! I've been listening to my favorite Atmos Albums and Atmos shows/movies just for the thrill. It's fantastic! While I recommend the entire package as soon as you can get it, you can go slow if you want. Get the Arc Ultra, add Sub 4, and then add the Eras 300 when you can afford to do so (you could even do the Eras 300 before and save the Sub for last if you want). You really should get everything, but if you have to go a couple months with only the Arc Ultra, it's one of the better soundbars to begin with! Very much recommended! ... show more
