How they differ in real use
Built from our best soundbars scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Polk Audio MagniFi Mini AX and the Sonos Beam (Gen 2) made our Top 5 Soundbars, at #3 (best value) and #4. The only sub-$500 system on this list that includes a physical wireless subwoofer alongside genuine Dolby Atmos and DTS:X certification, in a footprint barely a foot wide. It ranks above the similarly priced Sonos Beam because it adds real bass out of the box, though it lacks Wi-Fi streaming and a voice assistant. RTINGS' pick among Sonos options for smaller rooms: a compact 25.6-inch bar with virtualized Atmos and Trueplay room correction that sounds spacious for its size. It falls behind the MagniFi Mini AX here mainly on bass — there's no included subwoofer and no discrete height drivers, so overhead effects are entirely software-processed.

The widest gap is Value, where the Polk Audio MagniFi Mini AX scores 9 against 7 for the Sonos Beam (Gen 2) — performance per dollar. Surround/Atmos Performance also separates them: 8 for the Polk Audio MagniFi Mini AX versus 7 for the Sonos Beam (Gen 2). The Sonos Beam (Gen 2) claws back ground on Sound Quality and Connectivity & Smart Features.
