The Sonos Sub (Gen 3) is a premium wireless subwoofer designed to deliver deep, room-filling bass when paired with any Sonos speaker or soundbar system. Available in white, this subwoofer connects seamlessly to your existing Sonos setup over WiFi and is controlled through the Sonos app for easy setup and audio management.

The Sub Gen 3 features two force-canceling woofers positioned face-to-face inside its distinctive pill-shaped enclosure, which eliminates vibration and rattling while producing powerful low-frequency sound down to 25 Hz. An upgraded quad-core processor, increased memory, and updated wireless radios provide improved performance and future-proofing compared to earlier generations. Its versatile design allows it to stand upright or lay flat to fit any room layout, and its sealed, slot-ported cabinet keeps the drivers hidden for a clean aesthetic.

The Costco bundle includes a 30% off Sonos Accessories coupon and an $80 Apple or SiriusXM credit, redeemable within 90 days of purchase. The Sub Gen 3 is compatible with both newer and older Sonos speakers, including the Play:1, Play:3, Play:5 (Gen 2), and IKEA Symfonisk models. Dimensions are 15.3 x 15.8 x 6.2 inches and it weighs 29 pounds.
