Sonos Sub (Gen 3) — Wireless Subwoofer (Gloss Black)

The Sonos Sub (Gen 3) is the wireless subwoofer that adds true low-end to any Sonos system — home theater with Arc or Beam, or music zones with Amp. Gen 3 shares the same acoustic design as the current Gen 4 (the update was internal memory and radio), making it the smart-value way into Sonos bass.

Verified specs (per Sonos):

• Two force-cancelling drivers face inward — powerful bass with zero cabinet buzz or rattle
• Two Class-D digital amplifiers, one per driver, tuned to the acoustic architecture
• Dual precisely tuned acoustic ports; frequency response down to 25 Hz
• Trueplay tuning adapts output to your room; adjustable EQ in the Sonos app
• Wi-Fi connectivity plus 10/100 Ethernet port; pairs wirelessly with your Sonos system
• Place upright or lay flat — slides under furniture without muffling (drivers fire into the center opening)
• High-gloss black sculptural cabinet; 389 × 402 × 158 mm; 16 kg
• Works with Arc, Arc Ultra, Beam, Amp and more; pair with Sonos architectural speakers for install jobs

Ideal for: adding cinema-grade bass to a Sonos soundbar setup or an Amp-driven zone — pair it with the Arc Ultra, Beam Gen 2, or Sonos Amp from our catalog.
