Sonos Sub 4 - The Low Register

Sonos · $$$$

Sonos Sub 4 adds a dedicated low-frequency enclosure to a Sonos system without asking the main speakers to do every job. Its dual Sonos-engineered drivers work inside a ported enclosure with force-canceling acoustic architecture. That combination gives bass a defined source while the cabinet keeps its motion under control. The Sub 4 connects over WiFi and uses Trueplay room optimization to tune its response for the room rather than an idealized showroom. At 15.3 inches tall, 15.8 inches wide, and 6.2 inches deep, its footprint stays focused beside the listening system. It is not a general-purpose speaker. It is a dedicated subwoofer for a room already built around Sonos. The question is simple: does your system need more low end? If the answer is yes, the Sub 4 keeps that work in one measured enclosure.

Buying decision: Review the evidence, compare the alternatives, and choose this artifact when its strengths match your room, routine, and budget.
