Sonos Arc Ultra
Score: 85/100
Bobtot KW88
Score: 85/100Rankings
The Sonos Arc Ultra soundbar paired with the Sub 4 delivers a premium 9.1.4 Dolby Atmos experience with rich, detailed sound and deep bass, while integrating tightly with the Sonos ecosystem via Wi-Fi 6, Bluetooth 5.3, and eARC. Its sleek design and advanced calibration make it ideal for large-screen home theaters, though the lack of HDMI inputs and the heavy subwoofer are notable drawbacks.
The Bobtot KW88 (KW79) wireless surround system delivers 1000 W peak power, an 8" subwoofer, and extensive connectivity, making it a strong budget option for home cinema and karaoke, though it lacks Dolby Atmos and full eARC support.
