Sonos Beam Ultra review: A true Dolby Atmos soundbar for $699

The Sonos Beam Ultra costs $699 and adds two upward-firing Dolby Atmos speakers, five tweeters, four woofers and nine amplifiers. It is wider than earlier Beams and sounds close to the Arc, though its price nears the original Arc's $799.

• Priced at $699 versus $499 for the second-gen Beam
• Two upward-firing drivers deliver real Dolby Atmos
• Five tweeters, four woofers and nine amplifiers
• Wider body, still 2.5 inches tall and 6.35 pounds
