What reviewers say
Both reviewers praise the easy setup, room-filling sound and bass for the price, while noting the lack of smart streaming. WIRED finds it a straightforward TV upgrade, with less immersion than systems with rear speakers. Tom’s Guide likes its Atmos effects and dialogue adjustment but finds stronger voice and night modes reduce warmth, and movie bass can obscure quieter details.
