- The Sonos Sub 4 has dual drivers and a ported enclosure for deep, dynamic lows that add drama- You can pair it with compatible Sonos sound bars and speakers for deeper bass and more detail- There's no distortion here - the acoustic architecture creates a force-cancelling effect- Trueplay optimises the audio based on where you place the sub and other speakers in the room- It connects over WiFi, so you can place it anywhere in your room, like next to the sofa- The minimalist sculptural shape and matte finish means you won't want to hide it away
