Sonos Premium Entertainment Set with Arc Ultra

Sonos Premium Entertainment Set with Arc Ultra (Arc Ultra + Sub 4)

Sonos Premium Entertainment Set with Arc Ultra (Black) pairs Sonos’ most advanced soundbar with its most powerful subwoofer to create a cinematic home theater upgrade in minutes. Arc Ultra delivers ultra-precise, room-filling spatial audio with Dolby Atmos and an expansive 9.1.4 experience powered by 14 Sonos-engineered drivers and breakthrough Sound Motion technology for deeper, tighter bass from a slimmer design. Sub 4 takes low-end impact to the next level with dual force-canceling woofers that dig as low as 25 Hz while keeping distortion extremely low—so explosions hit harder, music feels fuller, and dialogue stays clean. With WiFi 6, Bluetooth 5.3 streaming, HDMI eARC/ARC connection (HDMI cable included), and app-based tuning features like Trueplay, Speech Enhancement, and Night Sound, this set is built for immersive movies, shows, sports, and music in medium to large rooms.
