The Sonos Sub (Gen 3) adds deep, powerful bass to any Sonos speaker or soundbar, completing a home theatre or hi-fi music system with two force-cancelling woofers that produce visceral low-frequency impact without vibrating furniture or floors. It wirelessly pairs with any Sonos speaker and self-tunes through the Sonos app's calibration routine to deliver tight, musical bass regardless of room size. Its sleek, slot-shaped design allows it to stand upright or lay flat under furniture, keeping your space tidy. For customers who want to feel as well as hear their music and movies, the Sub is transformative.
