Score: 52/100
Sonos Arc Ultra
Score: 89/100Rankings

The Sonos Arc Ultra paired with the Sub 4 delivers a premium 9.1.4 Dolby Atmos home-theater experience, featuring extensive codec support, Trueplay calibration, and sleek matte design. It excels in immersive audio and connectivity but is limited by a single HDMI port and the heft of the subwoofer.

The Sonos Sub 4 is a premium wireless subwoofer that delivers deep, precise bass down to 25 Hz and integrates flawlessly with the Sonos multi-room ecosystem. Its force-canceling drivers and app-driven calibration provide clean low-frequency performance, though its size, glossy finish, and limited connectivity may deter non-Sonos users.
