Certified refurbished Sonos Sub (Gen 3) in white, the current Sonos subwoofer for its home cinema and multiroom range, competing with premium wireless subs from Bose and Samsung soundbar ecosystems. “Certified refurbished” typically means it has been returned or opened, then fully tested, reset and approved for resale, with only light cosmetic marks possible compared with a brand new unit.
Who is this for?
If your Sonos Beam, Arc or Amp sounds clean but lacks real low end weight, this is the upgrade that changes the feel of films, TV and bass heavy music. Because it connects over WiFi and handles the lowest frequencies itself, your soundbar or speakers can play louder with less strain, keeping dialogue clearer at the same time. Setup is done in the Sonos app, and the sealed, force cancelling design helps reduce cabinet buzz in flats.
Gen 3 Sonos Sub: current generation with app based tuning (including Trueplay on supported iOS devices).
Wireless integration: pairs with compatible Sonos speakers without running an audio cable across the room.
