Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the Signa S2 for its dialogue-enhancing VoiceAdjust™ technology, solid midrange performance, and straightforward HDMI ARC integration, noting it outshines budget rivals like the Bose Solo 5 but criticizing its lack of immersive surround, limited codec support, and absence of smart-home features.
Everyday users overwhelmingly praise the sound bar's ability to make dialogue clearer and its hassle-free installation, with many calling it a noticeable upgrade over TV speakers; common complaints revolve around Bluetooth reliability, a small remote, aggressive power-saving shutdown, and the dusty fabric grille.

Professional reviewers consistently rate the Beam (Gen 2) as the top choice for small rooms, praising its Dolby Atmos performance, compact form factor and deep integration with the Sonos ecosystem, while noting its lack of DTS support, modest bass and the need for an eARC-compatible TV to unlock Atmos.
Everyday users love the Beam for its clear dialogue, easy setup and immersive Atmos feel in modest spaces, but many express frustration over the absence of Android Trueplay, thin bass and occasional voice-assistant lag.
