Sonos Sub Mini
Score: 76/100
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 Mini is a compact, wireless subwoofer that adds surprisingly deep bass to Sonos setups, ideal for small-to-medium rooms.
