Why each one made the list, and our final recommendation.
Bose Smart Ultra Soundbar
TechRadar found its sound wide and detailed, with a great build, but lacking weight and height effects. What Hi-Fi? liked the expansive sound and app, though mids can sound congested. It's the nearest Atmos rival here.
Bose Smart Soundbar
Tom's Guide found dialogue stays audible even in loud scenes, and liked its compact size and smart features. TechRadar thought it sounds good but a little pricey, with light bass and a narrow soundstage. It suits a bedroom or small lounge better than a big room.
Sonos Ray
What Hi-Fi? praised its excellent vocal clarity and punch for the size, though bass is limited. TechRadar heard big, balanced sound for such a compact bar, but notes it connects by optical, not HDMI.
Final recommendation: Want Atmos for less? The Bose Smart Ultra Soundbar is the closest match. The Bose Smart Soundbar suits small rooms and keeps voices clear. The Sonos Ray is the cheap fix for muddy TV speech. Keep the Arc Ultra for the deepest bass and fullest Atmos from one bar.
