Sonos Sub 4 [Subwoofer]

Sub 4 unlocks the full power of Sonos sound to immerse you deeper in every scene and song. Pair it with a Sonos soundbar or speaker for bass you can truly feel. Dual force-cancelling woofers deliver thunderous low end with virtually no distortion, all housed in an iconic design updated with a matte finish. Setup takes minutes — just plug in the power and connect via the Sonos app. Thanks to wireless connectivity, you can place Sub 4 anywhere in the room — even under a sofa. For true cinematic depth, pair two Sub 4s with Arc Ultra or Arc.
