Should I choose Sonos Arc Ultra or beam gen 2?

Verdict: Choose the Sonos Beam Gen 2 first if your budget is under $500 or if your space/console cannot fit a 46-inch soundbar; choose the Sonos Arc Ultra if you prioritize true 9.1.4 discrete Dolby Atmos immersion, deep bass, and direct Bluetooth playback for a large screen.

Choose the Sonos Arc Ultra for an immersive, discrete 9.1.4 Dolby Atmos home theater experience in larger spaces, or pick the Sonos Beam Gen 2 for compact, cost-effective TV audio in smaller rooms.

The Sonos Arc Ultra ($999 / £999) features a 46-inch wide enclosure housing 14 custom drivers (7 tweeters, 6 midwoofers, and a Sound Motion woofer) to deliver discrete 9.1.4-channel spatial audio, Bluetooth 5.3 connectivity, and 3-level Speech Enhancement. In contrast, the Sonos Beam Gen 2 ($449 / £449) delivers exceptional value at less than half the cost in a compact 25.6-inch footprint, utilizing a 5-driver array with psychoacoustic HRTF processing to virtualize Atmos height channels. Choose the Sonos Arc Ultra for flagship multi-channel immersion on TVs 55 inches and larger, or the Sonos Beam Gen 2 for tight spaces and efficient everyday audio.
