The Sonos Sub is a premium wireless subwoofer designed to enhance the audio experience in a variety of room setups. It delivers deep, impactful bass while minimizing distortion through its force-canceling drivers. The Sub is compatible with various Sonos home theater speakers and can be easily added to an existing Sonos system via the Sonos app. With a unique sculptural design, the Sub can be positioned either upright or horizontally, allowing for flexible placement in different spaces. The subwoofer also features adjustable audio settings, including volume control and phase adjustment, to tailor the sound to the room's acoustics. Two Subs can be connected simultaneously for an improved audio experience in compatible setups. Notably, it employs Trueplay tuning technology to adapt the bass output according to the specific acoustics of a room, ensuring optimal sound quality without harshness or muddiness. The Sub (Gen 3) is particularly suited for medium to large rooms, weighing about 29 lbs (13.15 kg), while the Sub Mini is ideal for smaller spaces at around 14 lbs (6.35 kg).
