The Sonos Beam Ultra is a $699 soundbar that delivers high-end Arc-like sound quality with genuine Dolby Atmos support via upward-firing speakers, making it a significant upgrade over the second-gen Beam's simulated Atmos. It features five tweeters, four woofers, and nine amplifiers in a slightly wider but still compact design, positioning it as a premium option for home theater enthusiasts seeking immersive audio without four-figure pricing.
