Polk Audio MagniFi Mini AX
Polk's ultra-compact Atmos soundbar, designed for small TV stands and apartments where a full-size bar won't fit. Based on published specifications and aggregated reviews including Tom's Guide, it is among the few sub-$500 systems that pairs a genuinely compact footprint with real Dolby Atmos and DTS:X certification and an included wireless subwoofer.

Our Verdict
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.

Alternatives to Consider
Samsung HW-Q990F
Samsung
Samsung's flagship Q-series soundbar for 2025-2026, a redesigned successor to the HW-Q990D with an updated wireless subwoofer and refined bass tuning. Based on aggregated reviews, it is the highest-scoring soundbar RTINGS has tested, combining a genuine 11.1.4-channel discrete surround system — soundbar, wireless subwoofer, and two wireless rear speakers, all included — with hardware Dolby Atmos and DTS:X decoding rather than software virtualization.
Sonos Arc Ultra
Sonos
Sonos's second-generation flagship soundbar, replacing the original Arc. Aggregated reviews consistently rate it among the best-sounding single-bar Dolby Atmos systems available, largely thanks to Sonos's new Sound Motion woofer design, which produces bass depth previously only achievable with an external subwoofer, paired with a 9.1.4-channel driver array for genuine height cues.
Sonos Beam (Gen 2)
Sonos
The compact sibling to the Arc Ultra in Sonos's current lineup, and RTINGS' pick among Sonos options for smaller rooms. Based on published specifications and aggregated reviews, it delivers a genuinely spacious, virtualized Dolby Atmos presentation and easy setup, but it is a five-channel system without any upward-firing drivers or an included subwoofer.
Vizio V-Series 2.1 Soundbar V21x-J8
VIZIO
Vizio's long-running entry-level 2.1 soundbar, still sold and reviewed years after its original 2021 release. Based on published specifications and aggregated reviews including RTINGS and Newsweek, it remains one of the most straightforward ways to meaningfully upgrade a TV's audio for well under $200, with a wireless subwoofer included and DTS Virtual:X surround processing.
